The invention provides an image sensor, an image processing method and electronic devices so as to solve the problem that the effect of an image extracted from the electronic devices is poor. The image sensor includes at least two sub-pixels. Each sub-pixel includes a photosensitive unit and a light intensity change detection unit. On the basis of the structure, the electronic device reads a firstelectrical signal which records a light intensity change and is output by each light intensity change detection unit; a target sub-pixel is selected from a sub-pixel set of the image sensor accordingto the first electronic signal, wherein an intensity value of the first electronic signal corresponding to the target sub-pixel is greater than or equal to a preset threshold; and an image is generated by using a second electrical signal output by the photosensitive unit corresponding to the target sub-pixel. In this way, when the light intensity value obtained by the sub-pixel changes, the target sub-pixel with the changed light intensity value is controlled to output the electronical signal so as to obtain the image of a shot object. Since the image does not need to be segmented, the effectof the image is good.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to an image sensor, an image processing method and electronic equipment. Background technique [0002] With the development of image processing technology, people often need to process the captured image, for example, to replace the background image of the character image, which requires first extracting the character image from the original image, that is, matting. The existing image matting technology usually detects the edge of the image to be extracted, obtains the edge contour of the image to be extracted, and then extracts the image to be extracted. [0003] However, when the edge of the image to be extracted is complex, it is difficult to accurately identify the edge contour of the image to be extracted, resulting in poor effect of the extracted image. Contents of the invention [0004] Embodiments of the present invention provide an image sensor, an image processing...
