1. A method for generating a High Dynamic Range (HDR) image with low bit width, comprising:
determining a to-be-processed HDR image with high bit width;
splitting the to-be-processed HDR image with high bit width to obtain N frames of split images which comprise a first frame to an Nth frame;
performing bit width reduction processing on the N frames of split images respectively, to obtain N frames of low-bit-width images; and
synthesizing the N frames of low-bit-width images to obtain the HDR image with low bit width.
