Title:
固体撮像素子、撮像装置、および、固体撮像素子の制御方法
Document Type and Number:
Japanese Patent JP7449663
Kind Code:
B2
Abstract:
In a solid-state image sensor that compares an amount of change in light amount and a threshold, time required to adjust the threshold is shortened.The solid-state image sensor includes a voltage comparison unit and a count unit. In the solid-state image sensor, the voltage comparison unit compares an analog signal according to an amount of change in incident light with a predetermined voltage indicating a boundary of a predetermined voltage range, and outputs a comparison result as a voltage comparison result. Furthermore, in the solid-state image sensor, the count unit counts a count value every time the voltage comparison result indicating that the analog signal falls outside the voltage range is output.
