Title:
An imaging device provided with a solid imaging device and it
Document Type and Number:
Japanese Patent JP6112306
Kind Code:
B2
Abstract:
A solid-state imaging device includes the following. Pixels arranged in matrix converts received light into signal voltage. A column AD conversion unit, which includes a comparison unit and an up-down counting unit, converts signal voltage to digital signal. The comparison unit compares a value of signal voltage to a gradually changing value of reference signal voltage. The up-down counting unit counts, by one of down-counting and up-counting, a time period until the comparison result is reversed if the signal voltage is of a base signal component of each pixel at reset level, and counts, by an other of down-counting and up-counting, the time period if the signal voltage is of a superimposed signal component in which the base signal component is superimposed on a pixel signal component corresponding to an amount of light received by the pixel. The comparison unit has switchable kinds of frequency band characteristics.
