Method and system for adjusting module display parameters when MIPI (mobile industry processor interface) module displays images

Abstract

The invention discloses a method and a system for synchronously adjusting display parameters of an MIPI (mobile industry processor interface) module when the MIPI module displays images. According to the method and the system, adjustment instructions and response parameters are received and transmitted through a frame blanking area of RGB (red, green, blue) signals. The method specifically comprises steps as follows: (1) the frame blanking area of the RGB signals is detected, and an identifier of the frame blanking area is generated; (2), when the identifier of the frame blanking area is detected, conversion from the RGB signals to MIPI signals is stopped, module parameter display and adjustment instructions cached in advance are converted into LPDT (lower power data transmission) data one by one and sent to the MIPI module; (3), after all the display and adjustment instructions in the frame blanking area are all transmitted and the response parameters returned by the MIPI module are received, a state indication signal is generated; (4), when the state indication signal is detected, an MIPI conversion control signal is generated, conversion from the RGB signals to the MIPI signals is started, and RGB image data are converted into the MIPI signals. With the adoption of the method and the system, the images are displayed in the MIPI module, meanwhile, the display parameters of the MIPI module are synchronously adjusted, and the image display quality of the MIPI module is not influenced.

Description

technical field [0001] The invention belongs to the technical field of MIPI signal processing, and more specifically relates to a method and system for synchronously adjusting display parameters of a MIPI module when the MIPI module displays images. Background technique [0002] In the research and development, production, debugging and testing of mobile industry processor interface (Mobile Industry Processor Interface, MIPI) modules, the modules are detected by letting the MIPI modules display different images; , it is necessary to set the display parameters of the MIPI module synchronously when the MIPI module displays the image, such as brightness, contrast, gamma value, color temperature, and the size of the red, green and blue components. [0003] Existing MIPI module display parameter setting methods, one is to set the display parameters of the module when the MIPI module is powered on and initialized, and the MIPI module display parameters cannot be adjusted synchrono...

Problems solved by technology

[0003] Existing MIPI module display parameter setting methods, one is to set the display parameters of the module when the MIPI module is powered on and initialized, and the MIPI module display parameters cannot be adjusted synchronously when the MIPI module displays images; the other, It is to forcibly change the MIPI signal mode and insert the MIPI module display parameters while the MIPI module is displaying the image. In this method, when the MIPI module display parameters are adjusted, the MIPI module screen may appear black screen, blurred screen or splash screen. Affect the module test results
