Abstract

The invention discloses an image sensor, a camera module and electronic equipment, the image sensor comprises a plurality of pixel units, each pixel unit comprises a photosensitive component, the photosensitive component comprises a photosensitive element, a first switch and an optical filter corresponding to a sensed color, the photosensitive element and the first switch are connected in series between a signal end and a grounding end, the light emitting surface of the optical filter faces the photosensitive element; a reset circuit which is connected between a power supply end and the grounding end, the reset circuit comprises a control module and a reset switch, and the output end of the control module is connected with the reset switch; an electric energy storage circuit which is connected between the signal end and the grounding end; and a processing module which is connected with the input end of the control module, and the structure of the image sensor can control the exposure capability of the pixel units in one exposure process.

Description

technical field [0001] The application belongs to the field of optoelectronic technology, and in particular relates to an image sensor, a camera module and electronic equipment. Background technique [0002] High-Dynamic Range (HDR) is high-dynamic lighting rendering. Compared with ordinary images, HDR can provide more dynamic range and image details, which are closer to the images seen by the human eye. [0003] In related technologies, a final HDR image is synthesized based on low dynamic range images with different exposure times and an exposure fusion (exposurefusion) algorithm, so that the final synthesized HDR image better reflects the visual effect in the real environment. [0004] In the process of implementing this application, the inventor found the following problems in the prior art. During the process of taking pictures by mobile terminal users, the HDR mode has too much difference in exposure of captured frames, the exposure fusion algorithm is difficult, and m...
