Bit depth concerns the number of bits used to convey tonality for each pixel, that is, black and white, gray-scale, or color. In general, the more bits per pixel, the larger the file size. For digital audio, bit-depth is the sample size, which determines the dynamic range of the file.
The number of colors a screen can display. 8 bit = 256 colors, 24 bit = millions of colors.
The term 'bit depth' refers to the number of bits used by a graphic input or output device to display the colour value of a pixel. Graphic cards in computers work with bit depths of up to 24 bit, for example. They thus have 8 bits available for coding each of the three colour components - red, green and blue - in the RGB mode and can thus display 224 or roughly 16.7 million colours. Modern scanners often have bit depths of 30 bits or more.
Refers to the color capacity of a pixel. For every bit, a pixel can carry one color.
Amount of information included in each pixel. The three most common bit depths are 8-bit, 16-bit, and 24-bit. Not all monitors support all bit depths.
The measure of the number of colors that a monitor is capable of displaying at one time.
The number of bits (binary digits) used to define a sample.
The bit rate and brightness resolution per pixel of a scanner; determines the contrast range of a digital image.
The resolution of a digital sample of sound. The higher the bit depth the higher the fidelity across the full range of sound frequencies.
A digital image is represented as a grid of dots called bits. The number of bits used to represent colors or tones. Generally the greater bit depth the better the detail.
The number of bits per palette index (in indexed-color PNGs) or per sample (in other color types). This is the same value that appears in IHDR.
Also referred to as colour depth is the number of bits used to describe the colour of each pixel. Greater bit depth allows a greater range of colours or shades of grey to be represented by a pixel, e.g.: - 1 bit is black or white (on or off) - 8-bit grayscale is 256 shades of grey - 8-bit colour is 256 colours - 16-bit colour is 65,536 colours - 24-bit colour resolution is 16.7 million colours - 30-bit or higher colour is billions of colours
Bit Depth Bit depth describes the file size of an image by orders of magnitude, based on how many color options of each single pixel. To calculate the maximum number of colors for an image of a particular bit depth, remember that the number of colors is equal to two to the power of what the bit depth is. For example, a GIF can support up to eight bits per pixel, and therefore can have as a many as 256 colors, since two to the power of eight equals 256. Such a GIF would have a bit depth of 8. A standard photographic image, such as a JPEG is considered a 24 bit image because of the millions of colors on its palette.
The number of bits that are used to store a pixel's color information for display. One byte is the basic unit of storage memory. One byte equals eight bits. One kilobyte (K, Kb) equals 1,024 bytes. One megabyte (M, MB) equals 1,024 kilobytes. One gigabyte (G, GB) equals 1,024 megabytes.
How many colors your monitor will show at one time, or how many different colors you can set an image to use. Common Bit Depths are as follows: 1 bit - Black and white 4 bit - 16 colors 8 bit - 256 colors 16 bit - Thousands of colors 24 bit - Millions of colors
is the string size in digital recording. Most digital devices record and play audio using bit depths of 16 or 24 bits. Audio CDs use 16 bits.
The number of bits used to represent each pixel in an image to determine its color or tone.
A digital image is represented as a bitmap (a grid of dots). The bit depth is the number of colour tones that can be associated with each dot. A one-bit colour can only contain two colours – black and white. But an eight-bit colour contains 256 shades (colour or grey), while a 24-bit colour contains 16.7 million shades.
The number of bits used to represent the colour of each pixel in a digital image, e.g. bit depth of 8 = 256 colours; bit depth of 16 = 65,536 colours; bit depth of 24 = 16 million colours. The more bits of information per pixel means more available colours and more accurate colour representation.
A CCD camera takes an analog signal which must be converted to a digital signal for the computer. This conversion is done by the A/D Converter. Each pixel has a value which is assigned a numerical value in the computer. The bit depth determines how finely each pixel value can be divided, meaning a greater bit depth can provide more information. A 12-bit A/D converter divides the signal into 4096 levels of information. A 16-bit converter provides 65,536 levels.
The number of bits per pixel assigned to store color information. More bits will yield a better reproduction even though a computer saves the data in a 24-bit format, because the computer will have a wider range of shades from which to choose when making the final conversion to 24 bits. Scanners with 36-bit color use up to 68.7 billion colors and are good for photo reproduction.
A measure of a computer monitor's ability to display different colors at the same time. While a monitor with a bit depth of 1 can only display monochrome information, a monitor with a bit depth of 4 can display 16 colors; an 8-bit monitor can display 256 colors and a 24-bit monitor can display 16.7 million colors. A 32-bit monitor has an additional 8-bits for transparency effects or masking as in the case of an Alpha channel.
Bit depth is the measurement of the amount of color information in an image for display or print. A higher bit depth translates to more color and a more accurate color indication in the digital image.
(Color Depth) Number of data bits used to define the color palette for each pixel in an image. Black and white uses one bit per pixel. Current color standards are 8-bit (One Byte, 256 colors), 16-bit (Two Bytes, "Thousands" of colors) and 24-bit (Three Bytes, "Millions" of colors) New technologies also allow 30-bit and 36-bit color.
The number of bits used to represent each pixel in an image, determining its colour or tonal range.
The number of bits used to represent colours or tones.
The number of colors or levels of gray scale a scanner or monitor supports. An 8-bit scanner can differentiate between 256 (28) levels of gray. A 12-bit scanner supports 212 = 4,096 levels of gray.
This refers to the color or gray scale of an individual pixel. A pixel with 8 bits per color gives a 24 bit image. (8 Bits X 3 colors is 24 bits.) CCD are colored in a pixel by pixel method. 30/32 bit color is billions of colors. (Only supported with high-end CPU´s.) 24 bit color resolution is 16.7 million colors. 16 bit color is 32,000 colors. (this is the Macintosh Standard) 8 bit color is 256 color. (this is the Windows Standard) 8 bit gray scale is 256 shades of gray 4 bit 64 colors or gray 2 bit black or white.
24-bit color, 8-bit color, 8-bit grayscale, 1-bit bitonal The number of bits used to define each image pixel. The greater the bit depth, the greater the number of tones (grayscale or color) that can be represented. Digital images may be produced in black and white (bitonal, lineart), grayscale, or color. Some new color display systems offer a 32-bit color mode. The extra byte, called the alpha channel, is used for control and special effects information.
Refers to the gray scale range of an individual pixel. A pixel with 8 bits per color gives a 24 bit image (8 bits X 3 colors is 24 bits). CCD are colored in a pixel by pixel method, see CCD. 30/36 bit is billions of colors; 24 bit is 16.7 million colors; 16 bit is 65,535 colors; 8 bit is 256 levels of gray or color; 4 bit is 16 levels of gray or color; 2 bit is black or white.
The number of bits dedicated to descibing a color. Each additional bit doubles the number of available colors.
The color depth of an image can be 1-, 2-, 4-, 8-, 16-, 24- or 32-bit color.
Number of bits used to store pixel information - higher the bit depth the more specific colour information that can be stored and the larger the file size. An 8-bit image is 2 to the power of 8 which is 256 colours. 24-bit will yield 16.7 million colours.
Channel bit depth is the number of computer bits per color channel used to store color and tonal information. Pixel bit depth is channel bit depth times the number of individual color channels. For more information, click here.
In colour images, the number of colours used to represent the image. Typical values are 8-, 16-, and 24-bit colour, allowing 256, 65,536 and 16,777,216 colours to be represented. The latter is known as true colour, because 16.8 million different colours is about as many as the human eye can distinguish. Also referred to as colour depth.
display: A characteristic/setting of a display card or Mac that determines how many colors you can show at once on a screen. 8-bit color allows 256 colors at once.
The number of bits used to represent each pixel in an image, determining it's color or tonal range.
A measure of the tonal resolution of a scanner or output device. For a scan, bit depth refers to the number of grays or color that are represented within each pixel. A one-bit scan can represent two levels: black and white. An eight-bit monochrome scan can represent 256 levels: black, white, and 254 levels of gray. A 24-bit color scan can represent over 16 million levels. For an output device, bit depth refers to the ability to vary either the size or the intensity of the smallest mark that they make.
How many bits it takes to represent the color in one pixel. The larger the bit depth, the more colors you can display and the more power it takes to display.
When an image is described as “x bit” with x being some number or other, what’s being talked about is the number of colors. In bitplane or raster graphics, each pixel has its color described by a string of bits, and the more bits there are per pixel the more possible colors there are. The number of colors equals two to the power of the bit depth, so one bit (or “one bitplane”) files can have only two colors, two bit can have four colors, three bit has eight colors and so on. The most common depths are 8 bit (256 colors) and 24 bit (16.8 million colors). Bit depths higher than 24 provide a wider color “gamut”, so image manipulation software can pull otherwise invisible detail out of the image.
The number of bits used to represent colors or tones. Bitmap - An image represented as pixels in a row and column format. (Note that Adobe refers to a bitmap as a two-color image.
The color depth or pixel values for a digital image. The number of possible colors or shades of gray that can be included in an image.
The number of bits per pixel. Bit depth determines the number of shades of gray or variations of color that can be displayed by a computer monitor. For example, a monitor with a bit depth of 1 can display only black and white; a monitor with a bit depth of 16 can display 65,536 different colors; a monitor with a bit depth of 24 can display 16,777,216 colors.
Refers to the color or grayscale of an individual pixel. A pixel with 8 bits per color produces a 24-bit image; 8 bits multiplied by three colors--red, green, and blue--equals 24 bits. CCDs are colored in a pixel-by-pixel method, using the following guidelines: 32-bit color (true color) contains billions of colors; suitable only for high-end use. 24-bit color (true color) contains 16.7 million colors. 16-bit color (high color) has 32,000 colors; the accepted standard for Macintosh. 8-bit color has 256 colors; this is the basic setting for Windows. 8-bit grayscale has 256 shades of gray. 4-bit is 64 colors or grays. 2-bit is black and white.
The number of bits that are used to store a pixel's colour information for display. One byte is the basic unit of storage memory. 8 bits = 1 byte; 1024 bytes = 1 kilobyte (kB); 1024 kilobytes = 1 megabyte (MB); 1024 megabytes = 1 terabyte (TB).
Refers to the colour or greyscale of an individual pixel. A pixel with 8 bits per colour gives a 24 bit image. (8 Bits x 3 colours is 24 bits.) CCD are coloured in a pixel-by-pixel method. 30/32 bit colour is billions of colours. (Only supported with high-end CPUs.) 24 bit colour resolution is 16.7 million colours. 16 bit colour is 32,000 colours (this is the Macintosh Standard), 8 bit colour is 256 colours (this is the Windows Standard), 8 bit greyscale is 256 shades of grey, 4 bit 64 colours or grey 2 bit black or white.
A digital image is represented as a bit-map (a grid of dots). Bit Depth is the number of color tones that can be associated with each dot. A 1-bit color, for example, can only contain 2 colors: black and white. But an 8-bit color contains 256 shades (color or gray), while a 24-bit color contains 16.7 million shades.
The number of binary bits that define the shade or color of each pixel in a bitmapped image. For example, a pixel in a black-and-white image has a depth of 1 bit, because it can only be black or white. The number of color values that a given bit depth can produce is equal to 2 to the power of the bit depth
The resolution available to assign a value to the recorded samples. To maximize the bit depth and achieve a better sounding recording, signal input levels should be kept close to digital maximum. Low resolution results in a "grainy" sound, that also contains quantization noise.
This refers to the grey scale range of an individual pixel. A pixel with 8 bits per colour gives a 24 bit image (8 bits X 3 colours is 24 bits). CCD sensors are coloured in a pixel by pixel method. 30/32 bit colour is billions of colours. 24 bit colour resolution is 16.7 million colours. 16 bit colour is 65,536 colours. 8 bit colour is 256 colours. 8 bit grey scale is 256 shades of grey. 1 bit is black or white.
The amount of data used to describe each pixel on the computer screen. i.e. Black & white linework is 1 bit deep. Greyscale is 8 bits deep. RGB is 24 bits deep. Images to be printed as CMYK separations should be 32 bits deep.

(1-bit, 8-bit, 24-bit) The amount of information (black and white or color) a computer can discern for each bit of an image. 1-bit is black and white (off or on), 8-bit is 256 "shades", "values" or "levels" of gray or 256 colors, 24-bit is millions of colors.
The number of bits contained in each sample of digital audio. The higher the bit depth, the more information recorded about a sample of audio, and therefore more closely resembling the original sound as heard by the human ear. Larger file size results from higher bit depth.
The amount of information (in bits) used to represent a pixel. A bit depth of 8 supports up to 256 colors; a bit depth of 24 supports up to 16,777,216 colors.
The maximum number of bits that are used to define a pixel. A measure of the defined brightness range.
The number of levels that a pixel might have, such as 256 with an 8-bit depth or 1,024 with a 10-bit depth.
The number of bits of color information per pixel. Graphics are often described by the number of bits used to represent each pixel. A 1-bit image is monochrome, an 8-bit image is 256 colors, and a 24-bit image displays in true color. Also often used to refer to the number of bits per sample in a sound file. See bit, pixel.
The number of bits (smallest unit of information in a notation using the binary system) that are digitized by a system's A/D converter.
From Portable Network Graphics (PNG) Specification (Second Edition) ( 2003-11-10) for indexed-colour images, the number of bits per palette index. For other images, the number of bits per sample in the image. This is the value that appears in the IHDR chunk .
The number of binary data bits used to record the brightness of each pixel per color channel. To achieve the illusion of continuous tone requires 256 levels of brightness from black (0) to white (255). This requires 8 bits binary. Since it takes three channels (Red Green & Blue) to represent color we need 24 bit (3x8) color to achieve full color RGB output and 32 bit color for CMYK.
