The image-sensing area of the TC254P is configured in 243 lines with 336 elements in each line. Twelve elements are provided in each line for dark reference. The blooming-protection feature of the sensor is based on recombining excess charge with charge of opposite polarity in the substrate. This antiblooming is activated by supplying clocking pulses to the antiblooming gate, which is an integral part of each image-sensing element. The sensor can be operated in a non-interlace mode as a 324(H) by 243(V) square color pixel mode by alternately averaging two red pixels for re...
