Abstract

The invention provides an image brushing method and an image brushing system. The image brushing method comprises that: an image input device linearly and continuously inputs image data by using a frame as a unit; an image cache caches the image data; an image brushing controller sends the image data to an FIFO according to a reading request; and an image display reads the image data from the FIFO according to a predetermined time sequence. The image brushing method also comprises the following steps of: detecting the FIFO; and if the FIFO is empty, generating a corresponding amount of supplementary data according to the predetermined time sequence, and sending the supplementary data to the image display. The method can solve the problem of screen crash caused by insufficient bandwidth of the image brushing system of a fixed time sequence.

Description

technical field [0001] The invention relates to image display technology, in particular to a method and system for brushing pictures. Background technique [0002] Many electronic devices, such as mobile phones, digital cameras, etc. will use the display panel (panel), which needs to read data to refresh the display panel, figure 1 It is a structural diagram of the image brushing system in the prior art. As shown in the figure, a FIFO (first-in-first-out memory) 101 obtains data from a image brushing controller 102 and provides the data to an image display 103 . [0003] When the image display is a panel such as DPI (DPI: DisplayPixelInterface, which is a display mode) or CCIR656 (CCIR: ConsultatiVeCommitteeofInternationalRadio, International Radio Consultative Committee) with a fixed timing, the image display 103 reads data from the FIFO at a fixed timing. When the system bandwidth was tight, the data input into the FIFO had been read by the image display 103, and now the ...
