A test pattern of specifically colored vertical bars used as a reference to test the performance of a color television
A standard color test signal displayed as columns, often accompanied by a reference audio tone. Color bars are used to adjust a video signal to maintain proper color from tape to computer, and through to output.
A standard color test signal, displayed as a video pattern of eight equal width columns (that is, “bars”) of colors. SMPTE color bars are a common standard. You adjust video levels against the color bars on your source videotape before digitizing.
Are a standard test pattern with white, yellow, cyan, green, magenta, red and blue bars that are used to make the color calibration on a display device.
Glassblowers using moderate amounts of color in their glass buy bars of concentrated colored glass about 1" in diameter and a foot long. This is cut in smaller chunks and melted, crushed or pulled. Sold by the kilo for a full bar, cost is effectively $1-3 per inch ($17-48 per kilo.) Those using more color tend to melt their own to reduce cost.
A video test signal usually put at the head of a tape to calibrate playback machines.
Standard test signal containing samples of primary and secondary colors, used as reference in aligning color video equipment. Generated electronically by a "color bar generator," often viewed on broadcast television in off-air hours. [See test pattern] color corrector : Electronic device that dissects the colors of a video signal, allowing them to be adjusted individually.
A video test signal widely used for system and monitor setup. Contains bands of color with fixed amplitudes and saturations.
Standard color test signal, displayed as rows or bars of color, used in the alignment of color video equipment.
A standard color valuation for alignment of videotape recording.
A video test image of eight vertical bars, each in a different color, used to test the color correctness of a TV or monitor.
A pattern generated by a video test generator, consisting of eight equal width color bars. Colors are white (75%), black (7.5% setup level), 75% saturated pure colors red, green and blue, and 75% saturated hues of yellow, cyan and magenta (mixtures of two colors in 1:1 ratio without third color).
Standard video test pattern which includes samples of primary and secondary colors.
A test signal used when synching and phasing video equipment. It contains vertical strips or bars of various primary and secondary colors. To see a picture of color bars click here.
An electronically generated video pattern consisting of eight equal width colors, used to establish a proper color reference before recording and playback* and for adjustment purposes.
A standard video waveform used to test the calibration of a video system. It consists of a sequence of the six primary and secondary colors plus white with a standard amplitude and timing. The color-bar sequence is white, yellow, cyan, green, magenta, red, and blue. There are several amplitude standards, the most common being 75% amplitude (brightness) with 100% saturation (intensity of the color).
