Kind Code:
A1
Abstract:
Disclosed is an image sensor. The image sensor comprises a plurality of pixel units, a plurality of exposure control modules, and an image processing module; the plurality of pixel units comprise three different sizes of photodiode (PD) columns used for absorbing RGB monochromatic light, each pixel unit in the plurality of pixel units comprises at least two rows of PD columns, and the plurality of pixel units are arranged according to a preset mode to form a plurality of rows of PD columns; in the plurality of exposure control modules, each exposure control module is correspondingly connected to one row of PD columns in the plurality of rows of PD columns; the plurality of exposure control modules are used for controlling the plurality of rows of PD columns to perform exposure according to a cross exposure mode of long exposure of one row of PD columns and short exposure of one row of PD columns so as to obtain a long exposure electric signal and a short exposure electric signal; and the image processing module is connected to the plurality of rows of PD columns and is used for generating a high dynamic range image by using the long exposure electric signal and the short exposure electric signal.
