US 2020/0404148 A1 · IMAGE OUTPUTTING METHOD AND ELECTRONIC DEVICE

Abstract

An image outputting method and an electronic device are provided. The method includes: shooting a scene by using a plurality of different exposure durations to obtain a plurality of images respectively; performing a summation operation according to the images to obtain a first image; adjusting a first brightness of the first image to an output brightness to generate a second image; respectively converting pixel values of a plurality of first pixels in the second image into other corresponding pixel values in another value domain to generate an output image; and outputting the output image.
