Point light source image detection method and electronic device

Abstract

This application relates to the field of image processing, and provides a point light source image detection method and an electronic device. The method includes: obtaining to-be-tested images, and determining pixel brightnesses of the to-be-tested images; determining low-brightness pixels and high-brightness pixels in the images based on the pixel brightnesses; filtering, based on the low-brightness pixels, out an image that does not meet a preset dark environment requirement, and filtering, based on the high-brightness pixels, out an image that does not meet a preset point light source size; and determining, based on a result of the filtering, whether a to-be-tested image is a point light source image. Pixels in images are classified into low-brightness pixels and high-brightness pixels. For the low-brightness pixels, the images are screened based on a preset dark environment requirement, so that the selected point light source images meet the preset dark environment requirement.
