Oblique line mobile module 4, which still produces, works as linea oblique anterior moving image, i.e., original image pixels circulation read operation original position not
Become, so then maintain when linea oblique anterior moving image show, every time when a frame image data of oblique line mobile image generation module 7
All after output, the image oblique line movement control image of control module 9 memory interface 1 reads the row of beginning two of original image again
View data is simultaneously cached in raw image data cache module 2, and controls image oblique line mobile module 4 to carry out same movement
Operation, from image memory interface 1 to oblique line mobile data cache module 5 during be all then constantly to be cached when a line operates
Next line, work as linea oblique anterior moving image in oblique line mobile image generation module 7 when image oblique line movement control module 9 detects
When output frame number reaches configuration frame number (now the data of present frame have all passed), then image oblique line movement control module 9 is same
Sample control image memory interface 1 inputs original image row data, and controls image oblique line mobile module 4 to carry out next moving image
Operation, i.e., start the cycle over reading from next mobile pixel, the interval of now next mobile pixel (such as from pixel 1,
Every 2 pixels, circulate and read since pixel 3) control module 9 is moved by image oblique line to control image oblique line mobile module
4 produce new moving image data.So as to realize the display of new moving image frame.
In above-mentioned technical proposal, when image oblique line movement control module 9 detects that oblique line mobile image generation module 7 is inner each
When the mobile totalframes of individual moving image output or movement reach totalframes or the total time that upper strata is configured total time, wait last
After the completion of one frame mobile image has exported, " whether can show that the image of last transportable frame still returns further according to set by upper strata
Echo show static original image " command operation, when to show last transportable frame, then image oblique line movement control module 9
Such as keep moving picture data constant, when to return to display original image, then stop the module of related moving operation, and control
Oblique line mobile image generation module 7 directly reads original image number by image memory interface 1 under RGB clock signal synchronizations
According to so as to export original static stationary data.
In above-mentioned technical proposal, no matter original static stationary image or each mobile image are output to the output of oblique line mobile image
