Abstract

The embodiment of the invention relates to the technical field of image detection, and particularly relates to a defective pixel detection method and device and electronic equipment. According to themethod, an original image is split into a plurality of single-channel images and the single-channel images are marked, then the marked single-channel images are combined to obtain a target image, pixels marked as preset marks are detected from the target image to serve as defective pixels, and therefore the defective pixels in the original image can be accurately detected.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image detection, and in particular, to a dead pixel detection method, device, and electronic equipment. Background technique [0002] During the production process of the lens module, due to the impact of the front-end process, the plastic will remain in the photosensitive area of ​​the image sensor (Sensor) and thus cover some pixels. During the actual imaging of the lens module, the covered pixels (dead pixels) cannot be imaged, and it is difficult to accurately detect the dead pixels in the existing technology. Contents of the invention [0003] In view of this, the present invention provides a dead point detection method, device and electronic equipment. [0004] The embodiment of the present invention provides a method for detecting dead pixels, including: [0005] acquiring an original image, and splitting the original image into multiple single-channel images; [0006] Ca...
