The target zone is a region comprising multiple pixels at this time.For another example tested TV switching menu option speed is being tested
Under test scene, test lead moves to right distant when tested TV is in menu box pop-up picture to tested TV transmission menu option
Control code, tested TV move to right remote control mode for after cursor right according to the menu option, and cursor is to right avertence in the image that screen is shown
It moves, the preset target zone of test lead can be at where former cursor, be also possible to after cursor moves at place.
Test lead obtains the RGB of each pixel in the target zone after determining the target zone of the screen picture
Value, it is to be understood that when target zone is a pixel, since radix is very few, may cause test lead and judge screen map
Therefore the whether changed result inaccuracy of the characteristics of image of picture when target zone is a region, can pass through calculating
Average value in target zone between the rgb value of all pixels point out, raising judge whether the characteristics of image of screen picture occurs
The accuracy of variation.
Whether step f judges the average RGB value in default RGB threshold range.
Step g, if the average RGB value is in the default RGB threshold range, it is determined that the screen picture meets pre-
If condition.
After test lead calculates the average RGB value of pixel in target zone, judge the average RGB value whether default
