SOLID STATE IMAGING APPARATUS |
摘要 |
A solid-state imaging apparatus including: a pixel section having a first pixel shielded from light and a second pixel provided in a region over which an object image is formed; a delay circuit having delay devices connected into a multiple of stages for giving to a running pulse a delay amount corresponding to a difference between an analog output value of each pixel from the pixel section and an analog reference value; an encoder to be reset by the unit of pixel with sampling and encoding a running position of the pulse at every predetermined timing; a first storage section for retaining an encoded value corresponding to the first pixel; a second storage section for retaining an encoded value corresponding to the second pixel; and a differential circuit for computing and outputting as a digital pixel signal a difference between an output from the first storage section and an output from the second storage section.
