Abstract: A signal processing apparatus includes an analog-to-digital conversion unit, a determination unit including a comparator, and a data calculation unit that performs calculation. The data calculation unit generates a first calculation result by performing calculation including processing for averaging a first digital signal and a second digital signal or processing for adding the first and second digital signals. The data calculation unit generates a second calculation result based on a difference between the first digital signal and first noise digital data. The data calculation unit switches whether to output the first calculation result or output the second calculation result, based on a comparison result of the comparator.

Abstract: In a photoelectric conversion apparatus, an amplification unit outputs a first amplified signal generated by amplifying a first signal using a first gain, a second amplified signal generated by amplifying the first signal using a second gain, a third amplified signal generated by amplifying a second signal using a third gain, and a fourth amplified signal generated by amplifying the second signal using a fourth gain to an analog to digital (AD) conversion unit in this order. The AD conversion unit generates first to fourth digital signals corresponding to the first to fourth amplified signals, respectively, and outputs the second digital signal and the third digital signal to an output unit prior to the first digital signal and the fourth digital signal.
