Image enhancement method, chip and image acquisition device

Abstract

Embodiments of the present application provide an image enhancement method, a chip, and an image acquisition device. The method comprises: storing, by a main processor, a preset number of Raw image frames to be processed currently acquired from a sensor in a first off-chip memory, into the on-chip memory; performing, by a first neural network processor, image fusion on a preset number of Raw image frames to be fused currently obtained based on the preset number of Raw image frames to be processed currently in the on-chip memory based on a preset image fusion network, to obtain a fused Raw image frame, and storing it into the on-chip memory; sending, by the main processor to an ISP chip, a target Raw image frame to be sent currently obtained based on the fused Raw image frame in the on-chip memory. Based on the above processing, image fusion can be performed on the Raw image frames sent by the sensor, during which noise in the Raw image frames can be removed, thereby improving the image quality of the sRGB image frames obtained by the ISP chip.
