Abstract:
1. An imaging apparatus comprising: a first pixel configured to generate a signal by photoelectric conversion; a second pixel, arranged in a row same as that in which the first pixel is arranged, configured to generate a signal by photoelectric conversion, wherein color filters respectively having a same color are provided on the first pixel and the second pixel; a first comparator configured to compare the signal based on the first pixel with a first reference signal of which a level is changed according to passage of time; a second comparator configured to compare the signal based on the second pixel with a second reference signal of which a rate of change for passage of time is different from that of the first reference signal; a first counter configured to perform counting until the first comparator outputs a signal indicating that a magnitude relation of the signal based on the first pixel and the first reference signal is inverted; a second counter configured to perform counting until the second comparator outputs a signal indicating that a magnitude relation of the signal based on the second pixel and the second reference signal is inverted; and a processing unit configured to generate one pixel signal based on a count value of the first counter and a count value of the second counter.
