SOLID-STATE IMAGING DEVICE AND DRIVING METHOD THEREOF, AND ELECTRONIC APPARATUS USING THE SAME

摘要

Provided is a solid-state imaging device including: a pixel array section that pixels which detect a physical quantities are arranged in two dimensions of matrix; an AD converting section that performs AD (Analog-Digital) conversion for a plurality of channels of analog pixel signals which are read-out from the pixel array section; and a control section that sets quantized units AD-converted by the AD conversion section according to a gain setting of the unit pixel signal, wherein the control section determines the grayscale number of digital outputs AD-converted for at least one channel of the unit pixel signals according to the gain setting of the pixel signal.

1. An imaging device comprising:
a first plurality of pixels configured to output a first illuminance signal; a second plurality of pixels configured to output a second illuminance signal; a first Analog-Digital (A/D) converter configured to convert the first illuminance signal into a first digital signal, wherein the first A/D converter includes a first counter; a second A/D converter configured to convert the second illuminance signal into a second digital signal, wherein the second A/D converter includes a second counter; and a combining circuit configured to combine the first digital signal and the second digital signal, wherein a value of the first illuminance signal is higher than that of the second illuminance signal.
