For example, user as shown in Figure 4 draws after an oval enclosed region on the screen under preference pattern,Terminal is determined the schematic diagram of highlight bar profile according to the track receiving.
The region that highlight bar profile comprises is the regional area of the highlighted demonstration of user's needs, highlight bar profile bagThe region that the extra-regional region containing is the region of common display or shows compared with low-light level.
Step 304, according to described highlight bar profile, sets up the image gain mould of the original image of described screen displayPlate;
Optionally, the situation such as resolution ratio, pixel of the system using according to terminal, determines described image gainThe gain rank of template, the rank that for example gains can be 8 grades, 1 grade the darkest, 8 is the brightest.
According to described gain rank, and the described highlight bar profile of determining, foundation and described screen displayThe display pixel of original image is image gain template one to one; Wherein, in described image gain template, instituteState yield value in highlight bar profile higher than the yield value outside described highlight bar profile. For example,, in highlight regionsPortion is used 6 higher stage gain ranks, outside 2 lower stage gain ranks, for example figure of using of highlight regionsShown in 5A and display pixel original image image gain template one to one.
Step 305, according to the pixel value of described original image and described image gain template, upgrades described original imagePixel value and obtain target image;
In the definite gain order template of step 304, what described gain rank was high and described gain rank is low is adjacentRegion can form the visual contrast that light and shade is strong, or can form the sawtooth problem of rectangle region different grey-scale,Transition is more stiff, and user's visual experience degree is poor. Therefore, the present invention is to institute in described image gain templateState gain rank height and the low adjacent area of described gain rank and carry out matching computing, obtain new image gainTemplate, the rank that makes to gain the luminance transition high and adjacent area that gain rank is low is more level and smooth, user's visionExperience better.
