Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] In the embodiment of the present invention, an image frame parameter update enabling signal is introduced to trigger image frame parameter switching update control, so that the present invention can successfully update image frame parameters in a timely, accurate and reliable manner.

[0017] In the embodiment of the present invention, a new group of image frame parameters is completely written into a designated register for latching, and when it is detected that a new group of image frame parameters is completely written into a designated register (i.e., the image frame After all the action...

Abstract

The invention is suitable for the digital picture processing technology area, supplies a method of renewing picture frame parameter, the picture frame parameter renewal method includes the following steps: After the picture frame parameter renewal prepares completely, picture frame parameter renewal to enable the signal set as effective; When receives the picture frame parameter promotion order, renewal picture frame parameter. In this invention implementation example, through the introduction picture frame parameter renewal to trigger carries on the picture frame parameter cut renewal control, thus enables this invention to be prompt, accurately, reliable achieves the successful renewal picture frame parameter; At the same time, avoided the picture frame parameter renewal preparation process not completing, but caused the picture frame parameter to renew the incomplete situation.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, in particular to a method for updating image frame parameters. Background technique [0002] With the continuous maturity and development of mobile multimedia technology, an LCD (Liquid Crystal Display, liquid crystal display) as a main display component has also been more widely used. At present, there are two mainstream LCD interfaces, MPU (Micro Processer Unit, microprocessor) interface and RGB (RedGreen Blue, red, green, blue) interface. Fig. 1 shows the connection structure of the LCD controller and the LCD driver chip in the prior art, wherein, the LCD controller is used to issue commands in the form of data, and the LCD driver chip is used to receive the command data of the LCD controller and execute the command, Control the action of the LCD display panel. The LCD driver chip with MPU interface has a buffer that can store one frame of image data inside, so after refresh...
