An array of electronic detectors of electromagnetic radiation, used at the focus of a telescope (or camera lens). A CCD acts like a photographic plate of very high sensitivity.

A light-sensitive device in digital cameras and scanners that captures the image. Also referred to as the image sensor.

The most common technology used today for imaging devices.

(CCD) A special type of memory that can store patterns of changes in a sequential manner. The light-detecting circuitry contained in many still and video cameras is CCD.

A type of sensor used in many FLATBED SCANNERS, particularly consumer-quality scanners, and in camcorders. A CCD converts light into electrical impulses. CCDs tend not to be sensitive to low areas of light; for this reason, CCD scanners usually produce scans which lack detail in the shadows.

An imaging sensor that reacts when light strikes its surface, recording digitally the magnitude of the sensed light. In traditional designs, a colored filter overlaid on a CCD or a CMOS lets the sensor record the magnitude of red, green, and blue light. The sensor uses this data to build a digital picture. Some higher-end video cameras use a three-CCD system, in which each chip is dedicated to an individual color, so filters aren't required.

a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel in the image is converted into an electrical charge whose intensity is related to a color in the visual spectrum

an integrated circuit chip consisting of an array of electronic light sensitive elements

an intra-oral silicon sensor, sensitive to X-rays, that is directly connected to a computer

a semiconductor device in which charge stored in a surface layer can be moved about the surface by applied fields or impacting radiation, and such devices are now in common use as electromagnetic radiation sensors

a solid state electronic device that converts light into an electric charge

The new age imaging device, replacing the old tubes. When first invented in the 1970's, it was initially intended to be used as a memory device. Most often used in cameras, but also in telecine, fax machines, scanners, etc.

A special type of chip that can convert light into electronic signals. A DV camera focuses light through a lens and onto a CCD where it is converted into electronic signals that can be stored on tape.

Most digital cameras use an array of electronic, CCD image sensors to capture scenes. The resolution of the CCD determines the resolution of the camera. CCD resolution is usually somewhat higher than the maximum image resolution.

A computer chip with light-sensitive rows and columns of pixels. Modern astronomical cameras use CCDs to collect and store light from celestial objects over the length of an exposure. This data is then translated into images.

CCTV cameras that are CCD will give sharper, better defined pictures. All professional level cameras will be CCD.

CCD Sensor used in scanners to read documents being scanned into memory.

An electronic device used to detect photons, composed of many tiny pixels, each of which records a buildup of charge to measure the amount of light striking it. [More Info

a charge-transfer device that collects photocharge in pixels and then uses clock pulses to shift the charge along a chain of pixels, bucket-brigade style, to a charge-sensitive amplifier. An "interline" CCD places a light-shielded CCD next to a corresponding line of photodiodes that collect the charge and then move it to the CCD ( Figure A). CCDs deliver pixel-by-pixel analog signals at their output. CCD imaging provides good dynamic range and dynamic response.

The type of image sensor used in scanners.

A CCD is an electronic device consisting of an array of photosensitive elements, used to record images.

or CCD- A semiconductor element that measures the intensity of light falling upon it. It outputs a voltage proportional to the intensity of that light. In a digital camera, CCD's are arrayed in a rectangular shape to capture an entire image at once. In a scanner, they are a linear array that is then scanned across the image, capturing one line at a time.

A light-sensitive imaging silicon chip used in cameras.

A semiconductor technology used to make, among other things, the solid-state image sensors used in camcorders.

A light-recording device that has revolutionized modern astronomy. A CCD is a silicon wafer, about the size of a thumbnail, that converts light into an electronic signal which may be manipulated and stored on a computer. CCD recording efficiency is very high, about 80 to 95 percent, compared to its predecessor, photographic plates, which have an efficiency of about one percent. Astronomers mount CCD chips into cameras on telescopes, allowing them to see 9 to 10 times farther out into space than they could with photographic plates.

For imaging devices, a self-scanning semiconductor array that utilizes MOS technology, surface storage, and information transfer by shift register techniques.

A type of solid-state sensor used in scanners that captures light reflected or transmitted by original.

A charge-coupled device (CCD) is a sensor for recording images, consisting of an integrated circuit containing an array of linked, or coupled, capacitors. CCD sensors and cameras tend to be more sensitive, less noisy, and more expensive than CMOS sensors and cameras.

A light-recording device that revolutionized astronomy. A CCD is a silicon wafer, about the size of a thumbnail, that converts light into an electronic signal which may be manipulated and stored on a computer. In addition, the CCD recording efficiency is high, at about 80 to 95 percent, compared with the low photographic efficiency of film (about one percent). Astronomers mount CCD chips into cameras on a telescope, allowing the astronomer to see 80 to 95 percent farther out into space and time.

An electronic device that consists of a regular array of light sensitive elements that emit electrons when exposed to light.

(CCD). An image sensor that reads the charges built up on the sensor's photosites a row at a time.

Technology which uses a shift register combined with photo-diodes to create an imaging device. The size of the CCD chip is normally 1/4", 1/3" or 1/2". As a rule of thumb, the larger the size, the higher the quality of the image produced. However some of the higher density 1/4" and 1/3" CCD chips can now produce as good an image as many of the 1/3" or 1/2" chips.

See CCD.

An electronic device consisting of a large array of light-sensitive elements used to record very faint images. Also used as "electronic film" in digital cameras and portable video recorders.

A charge-coupled device (CCD) is an , consisting of an integrated circuit containing an array of linked, or coupled, light-sensitive capacitors. This device is also known as a Color-Capture Device.
