Abstract: An electronic device and an automatic exposure convergence method are provided. The electronic device includes an image sensor and a processor. The image sensor is configured to obtain a first frame. The first frame includes a plurality of sub-frame regions, and each of the sub-frame regions includes a plurality of pixel data. The plurality of pixel data are obtained based on different exposure times. The processor is coupled to the image sensor. The processor is configured to analyze the first frame to combine the pixel data having the same exposure times in the sub-frame regions into a plurality of second frames. The processor analyzes the plurality of second frame to obtain a plurality of exposure values. The processor performs an exposure convergence operation based on the plurality of exposure values.
