... Hot pixels are pixels which produce greater than 25,000 electrons per second. The hot pixels are found by examining the flat field image (In this particular case not corrected for dark current as this would have the effect of removing most of the hot pixels). As the measurements were taken at room t ...

... Either brigtnesses are changing too slowly to be noticed, or the brightnesses are changing too quickly, causing visible transitions between regions of pixels that differ in value by one. The latter situation can occur at low intensities. Our eyes are more sensitive to changes at low intensities. We ...

CTIA and GTIA

Color Television Interface Adaptor (CTIA) and its successor Graphic Television Interface Adaptor (GTIA) are custom chips used in the Atari 8-bit family of computers and in the Atari 5200 console. In these systems, a CTIA or GTIA chip works together with ANTIC to produce video display. ANTIC generates the playfield graphics (text and bitmap) while CTIA/GTIA provides the color for the playfield and adds overlay objects known as player/missile graphics (sprites). Under the direction of Jay Miner, the CTIA/GTIA chips were designed by George McLeod with technical assistance of Steve Smith.Color Television Interface Adaptor and Graphic Television Interface Adaptor are names of the chips as stated in the Atari field service manual. Various publications named the chips differently, sometimes using the alternative spelling Adapter or Graphics, or claiming that the ""C"" in ""CTIA"" stands for Colleen/Candy and ""G"" in ""GTIA"" is for George.
