Abstract

The invention relates to an image display circuit, an image display method and image display equipment, and the image display circuit comprises an image capturing module which is used for capturing afirst image and outputting the first image to the image display module through a preset transmission mode; the image processing module is used for processing the data input by the memory through the memory transmission mode to generate a second image, and outputting the second image to the image display module through the preset transmission mode or the memory transmission mode; and the image display module is used for outputting the first image and the second image to a display screen after aliasing the first image and the second image, and the memory space and the memory bandwidth required for data transmission in the preset transmission mode are both smaller than the memory space and the memory bandwidth required for data transmission in the memory transmission mode. Through multiple circuit connection modes, the memory bandwidth is reduced, the memory capacity is reduced, and the performance of a chip system is improved.

Description

technical field [0001] The invention relates to the technical field of image processing and display, in particular to an image display circuit, an image display method and an image display device. Background technique [0002] With the development of technology, video images have been widely used in all aspects of life, and mobile phones, TVs or other electronic devices can capture, process and display images. In the existing image display circuit, the image capture module, image processing module and image display module are all connected to the memory. Due to the high real-time requirements for image capture, processing and display, the image capture module, image processing module and image processing module are required. The display module accesses the memory at the same time. At this time, there is a great demand for the bandwidth of the memory, and it also occupies a large amount of memory space, which seriously affects the performance of the chip. [0003] How to eff...
