Abstract
A signal processing method for converting analog signals to digital signals of different bit numbers using a sloped ramp signal includes first A/D conversion for converting an analog signal to a digital signal of a first bit number using a first ramp signal with a first slope or converting the analog signal to the digital signal of the first bit number using a second ramp signal with a second slope, and second A/D conversion for converting an analog signal to a digital signal of a second bit number using a third ramp signal with a third slope or converting the analog signal to the digital signal of the second bit number using a fourth ramp signal with a fourth slope, wherein a ratio of the second slope to the first slope is lower than a ratio of the fourth slope to the third slope.
