This measures the maximum amount of individual picture elements recognizable in a single scanning line.

A number that specifies the amount of fine detail a video display can show (or a video format can contain) in each horizontal scanning line. In analog formats such as VHS videotape and CRT-based television sets, horizontal resolution is expressed in TV Lines (TVL). In digital formats and fixed-pixel display devices, horizontal resolution is expressed in the number of pixels per horizontal line of video. For example, VHS has a horizontal resolution of 240 TVL, DVD has a horizontal resolution of 720 pixels, and HDTV's maximum horizontal resolution is 1920 pixels. Technically, horizontal resolution is specified as the number of pixels or TVL per picture height. This requirement prevents widescreen formats from having an apparently higher horizontal resolution than 4:3 formats.

Specification denoting an amount of discernible detail across a screen's width. Measured in pixels, the higher the number the better the picture quality.

Rating of the fine detail ( definition) of a TV picture, measured in scan lines. The more lines, the higher the resolution and the better the picture. A standard VHS format VCR produces 240 lines of horizontal resolution, while over 400 lines are possible with S-VHS and Hi-8 camcorders.

The number of vertical lines (or pixels) that can be resolved from one side of an image to the other. Horizontal resolution is a trickier concept, because while the vertical resolution of all analog (NTSC) video sources is the same (480 lines), the horizontal resolution varies according to the source. Some examples for typical sources: VHS VCRs (240 lines), analog TV broadcasts (330 lines), non-HDTV digital satellite TV (up to 380 lines), and DVD players (540 lines). DTV signals have horizontal resolution that ranges from 640 lines for SDTV, to 1280 lines (for 720p HDTV) or 1920 lines (for 1080i HDTV).

In facsimile, the number of picture elements per unit distance in the direction of scanning or recording.

The number of vertical lines which can be resolved in a picture, depending on the number of pixels in a chip

A number used to measure the ability of a camera or monitor to accurately reproduce a picture with many small picture elements. A resolution chart is used when testing a camera. The chart has several circles one large one in the center with lines in a fan shape converging in the center. The lines are marked with resolution numbers which increase as the lines become closer to each other and the center. The maximum resolution displayed on the chart is 800 lines. The more common CCTV cameras are capable of producing from 350 to 500 lines of resolution.

The number or horizontal lines that a device can reproduce and still have the lines viewable. The higher the number of horizontal lines, the sharper, clearer and better it looks.

A rough guide to picture quality that measures the number of distinct vertical lines that can be displayed across the width of a TV screen before they blur together. For instance, 540 lines of horizontal resolution (the maximum output for the MiniDV video format) means that a TV can display 540 alternating black and white lines. The larger the number of distinct lines, the better the picture detail and clarity.

The number of picture elements with a single scanning line.

In a television scanning system, the specification of resolution in the horizontal direction, meaning the ability of the system to reproduce closely spaced alternating black-and-white vertical lines of detail across the screen. The number of alternating black ducd-white lines is divided by the aspect ratio (usually 3/4) to make comparison between horizontal and vertical resolution easier. This number is usually expressed as TV lines per picture height.

Chrominance and luminance resolution (detail) expressed horizontally across a picture tube. This is usually expressed as a number of black to white transitions or lines that can be differentiated. Limited by the bandwidth of the video signal or equipment.

the number of vertical lines on a test chart clearly visible (resolved) by the horizontal scanning lines. The higher the number the clearer the picture. VHS ad 8mm systems resolve around 24O lines, while S-VHS and Hi8 resolve 4OO.

Horizontal Resolution: Smallest increment of a television picture that can be discerned in the horizontal plane. It is measured in TV lines per height.

See lines of horizontal resolution.

The number of vertical lines from one side of an image to the other. The horizontal resolution of both NTSE standard analog and ATSC stand digital video may vary according to the source.

Quality value of a displayed image relating the number of vertical lines of information (up and down lines) used to make up an image.

The maximum number of individual picture elements that can be distinguished in a single scanning line.

The number of vertical lines that can be perceived in a video device.

A rating of the fine detail of a TV picture, measured in lines. The more lines, the higher the resolution and better the picture. A standard VHS format can produce 240 lines of horizontal resolution, while over 400 lines are possible with Super-VHS, Hi-8, and laser disc players. Not to be confused with vertical resolution, which is the same for all formats.

The amount of discernable detail across a screen's width. Measured in lines, with higher numbers corresponding to increased picture quality. [See resolution.

The total number of vertical lines individually perceived across the horizontal rows of a monitor.

The number of vertical lines that a system is capable of producing (counted on a horizontal axis).

Specification denoting amount of discernable detail across a screen's width. Measured in lines, the higher the number the better the picture quality. (See resolution.)

The horizontal lines on a TV screen; the higher the number of lines, the better the resolution is.
