Problems solved by technology
Here, since the multi-frame synthesis algorithm needs to move the image sensor accurately by one pixel each time, and requires multiple exposures, and then aligns and synthesizes the multi-frame images, this has advantages in position control and image processing. High difficulty, it is difficult to guarantee the quality of the processed image
Therefore, for existing image sensors, it is not only difficult to improve image quality through these algorithms, but also has poor accuracy. Therefore, it is necessary to propose a new image sensor structure that is conducive to improving image quality

The present application discloses an image sensor, a camera module, and electronic equipment. The image sensor includes a plurality of pixel units, and the pixel units include: at least two photosensitive components, and different types of photosensitive components correspond to different sensing colors. The photosensitive component includes a photosensitive element, a first switch, and a filter corresponding to the sensed color. The photosensitive element and the first switch are connected in series between the signal terminal and the ground terminal, and the light-emitting surface of the optical filter faces the a photosensitive element; and an electric energy storage circuit, the electric energy storage circuit includes a capacitor, and the electric energy storage circuit is connected between the signal terminal and the ground terminal. The structure of the image sensor is beneficial to improve the quality of the collected images.
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] Image sensors are devices that convert light signals into electrical signals. An image sensor includes a plurality of pixel units. Each pixel unit of an existing image sensor has a photosensitive element and a color filter. These pixel units are arranged in a Bayer array, for example. Here, since the filter of each pixel unit only allows light of a single color to pass through and be received by the photosensitive element, a single pixel unit will only be able to obtain red (Red, R), green (Green, G) and An optical signal of one color in blue (Blue, B), and convert the optical signal into an electrical signal output, which makes the resolution of each color image lower, for example, according to the arrangement structure of the Bayer array, The resolution of the G imag...
