Image processing system, method and device

Abstract

The present invention discloses an image processing system, a method thereof and a device to solve the problem of poor size compatibility of a processed image in an ISP architecture in the prior art. The system comprises an image sensor for obtaining an image, a sampling module for sampling a received video image according to the image resolution configured by an image sensor and the maximum line resolution processed by an ISP module, the ISP module used for receiving a video image transmitted by the sampling module, carrying out image processing on the video image, reading the static state image currently stored in a memory according to the maximum line resolution processed by an ISP module, carrying out image processing on the static state image, and sending the processed image to the memory, and the memory for storing the image. In addition, the configuration of processing the size of the image by the ISP module is not needed, the need of line buffer in the image processing process is reduced, and the problem of the poor size compatibility of the image processed by the ISP module is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing system, method and device. Background technique [0002] In various multimedia devices (such as digital cameras, mobile phones, tablet computers, etc.) capable of video shooting and photographing in the prior art, there are image sensors for acquiring images and multimedia processing chips for image processing. Wherein, the image sensor includes a Complementary Metal-Oxide-Semiconductor (CMOS) image sensor, a Charge Coupled Device (Charge Coupled Device, CCD) image sensor, and the like. [0003] Most of the multimedia processing chips have an image signal processor (Image Signal Processor, ISP) module, which is used to process the image acquired by the image sensor. These ISP modules are generally designed for a specific specification, such as , an ISP module is designed for an image size of 500W pixels, and the multimedia processing chip containing th...
