AI Technical Summary

Technical Problem

When recording the brightness of the picture at the moment of shooting, the image sensor in the prior art ignores the information of the light source in the environmental scene, resulting in a large difference between the image perceived by the human eye.

Method used

The filter unit and a pixel unit are provided in the sensor. The filter unit includes an RGB filter and a variety of narrowband filters. The photosensitive pixels in the pixel unit are arranged corresponding to the RGB filter or narrowband filter. Multi-spectral information is obtained through the multiple narrowband filters for color correction for subsequent image processing.

Benefits of technology

By obtaining real spectral information in the environment, the realism of the image picture is improved, the difference between the image and the human eye is improved, and the accuracy of image processing is improved.
