SOLID STATE IMAGING DEVICE, METHOD OF OUTPUTTING IMAGING SIGNAL AND ELECTRONIC DEVICE

摘要

There is provided a solid state imaging device including a first analog-to-digital converting unit that compares a level of an analog reference signal with a first inclination with a level of an analog pixel signal output from a pixel array unit, and converts the analog pixel signal into a first digital pixel signal, a second analog-to-digital converting unit that compares a level of an analog reference signal with a second inclination that is different in inclination from the analog reference signal with the first inclination with a level of the analog pixel signal, and converts the analog pixel signal into a second digital pixel signal, and a digital compositing unit that composites the first digital pixel signal with the second digital pixel signal, and outputs a composite result.

1. An imaging system comprising:
a pixel array including a plurality of pixels; a first analog-to-digital converter coupled to at least one of the plurality of pixels and configured to convert an analog signal into a first digital signal based on a first reference signal; and a second analog-to-digital converter coupled to the at least one of the plurality of pixels and configured to convert the analog signal into a second digital signal based on a second reference signal which is different from the first reference signal, wherein the first digital signal and the second digital signal are composited to generate a composited signal.
