Abstract
An electronic device and a high dynamic range (HDR) image generation method therefore are provided. The electronic device includes an image sensor and a processor, wherein the processor can be configured to adjust the exposure of the image sensor so as to acquire a first image having a first brightness and a plurality of second images having a second brightness, perform, on the first image, brightness conversion and noise attenuation of at least a first intensity so as to provide a third image having the second brightness, and generate a second HDR image on the basis of the first image and the third image, and generate a second HDR image on the basis of the first HDR image and the plurality of second images.
