发明名称 Image sensor and an electronic information device
摘要 An image sensor is disclosed. The image sensor includes a plurality of pixels arranged in a matrix which detects a pixel signal of each pixel based on a voltage difference between a reset voltage which is a reference voltage of each pixel and a signal voltage generated by a photoelectric conversion at each pixel, and includes a plurality of read lines located for each pixel column, wherein the reset voltage and the signal voltage are read from the pixel of the corresponding pixel column; and a reset current supply section provided for each read line, wherein at the same time a first reset current is supplied from a pixel to the read line when reading the reset voltage from the pixel, the section supplies a second reset current to the read line such that a sum of the first reset current and the second reset current is constant.
