Abstract

The invention discloses multi-core displaying control method and device. The device comprises at least one TMDS (Transition Minimized Differential Signaling) signal receiver, at least one DP signal receiver, at least one VGA (Video Graphics Array) signal receiving and converting device, at least one analog video signal receiving and converting device, a frame buffering and DDR (Double Data Rate) control device, a DDR module, an OSD engine module, a multi-port LVDS (Low Voltage Differential Signaling)/ V-by-One/eDP sending module, and at least four groups of scale processing modules, and gamma, color correction and video enhancing modules, wherein the at least four groups of scales addressing modules and gamma, color correction and video enhancing modules are sequentially connected. According to the multi-core displaying control method and device, the scale processing modules and the gamma, color correction and video enhancing modules are used for individually adjusting and controlling a display picture, so as to realize high-resolution display of the picture and random combination of a plurality of picture arranging modes, and the display quality of a contrast picture or a splicing picture is ensured; the method and device are particularly applied to popularization and application in the medical treatment, graphic design and advertisement industries.

Description

technical field [0001] The invention relates to a method and device for display control of a display, in particular to a display control method and a controller with multi-cores that are good in applicability, strong in professionalism, and display multiple images at the same time. Background technique [0002] In professional fields such as medical imaging and graphic design, image comparison is usually required to judge the difference between images. Among them, in disease diagnosis, good image contrast can improve the accuracy of judgment and ensure the treatment effect; while in graphic design, higher image resolution and image contrast quality can truly reflect the design effect and ensure that the design scheme is optimal. way to present. Therefore, good image contrast and display becomes the key to the needs of such special industries. [0003] In the prior art, in order to realize the above-mentioned process, the display control method of two-way signal input is ma...
