The embodiment of the invention provides a kind of method of brightness adjusting, and as shown in Figure 3, the method may further comprise the steps:
The user is when reading electronic book or browsing page, send the request message of local highlighted demonstration by menu option, behind the request message of the local highlighted demonstration that terminal reception user sends, enter the preference pattern of highlighted demonstration, and the e-book page of the current reading of auto-returned user or the Webpage of browsing.
Under described preference pattern, the user delineates out highlight bar according to the demand of oneself at screen, and terminal receives the track that described user delineates by touch screen; After detecting the described touch screen of release, determine the highlight bar profile according to described track.
Optionally, the user goes out to need the edge track in the zone of highlighted demonstration by unicursal on the screen of terminal, wherein, the shape that unicursal goes out can be a point, perhaps simple lines, the perhaps enclosed region such as ellipse or rectangle etc., the size in the length of track or zone can arbitrarily be delineated.
After the user delineated and finishes, terminal can detect the operation that the user discharges described screen, at this moment, the track that the user delineates may not show or when not having closure fully, terminal by match computing or other compute mode, estimates suitable highlight bar profile according to the track that receives.
For example, when the screen of user under preference pattern drawn a point, after then terminal receives a little track, around point, form the gradual change hot spot of a circle, at this moment the i.e. circular edge of hot spot for this reason of highlight bar profile.When the screen of user under preference pattern drawn simple lines, for example draw a horizontal line, after then terminal receives the track of this horizontal line, around horizontal line, form a light belt, this moment, the highlight bar profile was the edge of light belt.When the screen of user under preference pattern drawn an oval enclosed region, this moment, the highlight bar profile was the closed figures that closed user is delineated.
For example, after the screen of user as shown in Figure 4 under preference pattern drawn an oval enclosed region, terminal was determined the synoptic diagram of highlight bar profile according to the track that receives.
The zone that the highlight bar profile comprises is the regional area of the highlighted demonstration of user's needs, and the extra-regional zone that the highlight bar profile comprises is the zone of common display or the zone that shows than low-light level.
Step 304 according to described highlight bar profile, is set up the image gain template of the original image of described screen display;
Optionally, the situations such as the resolution of the system that uses according to terminal, pixel are determined the gain rank of described image gain template, and the rank that for example gains can be 8 grades, namely 1 grade the darkest, 8 is namely the brightest.
According to described gain rank, and the described highlight bar profile of determining, the display pixel of the original image of foundation and described screen display is the image gain template one to one; Wherein, in the described image gain template, the yield value height that the yield value in the described highlight bar profile is outer than described highlight bar profile.For example, highlight regions is inner uses 6 higher gain per stage ranks, and highlight regions is outside uses 2 lower gain per stage ranks, for example shown in Fig. 5 A and display pixel original image image gain template one to one.
Step 305 according to pixel value and the described image gain template of described original image, is upgraded the pixel value of described original image and is obtained target image;
In the gain order template that step 304 is determined, described gain rank height and the low adjacent area of described gain rank can form the strong visual contrast of light and shade, perhaps can form the sawtooth problem of rectangle region different grey-scale, transition is more stiff, and user's visual experience degree is relatively poor.Therefore, the present invention carries out the match computing to the rank height of gain described in the described image gain template and the low adjacent area of described gain rank, obtain new image gain template, so that gain rank the luminance transition high and adjacent area that the gain rank is low is more level and smooth, user's visual experience is better.
For example shown in Fig. 5 B, by the Fitting Calculation or other method of estimation, the gain rank at highlight regions edge is that 6 grades and gain rank are that the gain rank of 2 grades adjacent area is 3 grades or 4 grades, so that the gain rank seamlessly transits, thereby brightness also can seamlessly transit.
Optionally, the yield value according in the pixel value of described original image and the corresponding described new image gain template upgrades the pixel value of described original image and obtains target image; Described pixel value can comprise color and gray scale, and wherein, color is for to make up the shades of colour that accesses by three kinds of basic colors of RGB, the bright dark degree of gray scale presentation video, and gray scale is represented by gray-scale value.
For example, with the pixel value of original image and pixel value after yield value in the corresponding described new image gain template obtains to upgrade by product calculation, for example, the a certain pixel value of original image is 100, if the gain rank is up to 8 grades, during yield value 6 in the new gain template, the pixel value after then upgrading is 100* (6/8)=75, i.e. 75% of original brightness.For example be target image shown in Fig. 5 C, the highlight regions in the target image is adjacent the gradual change that the zone presents brightness, so that brightness seamlessly transits, user experience is higher.
Optionally, after the ratio of each yield value in the image gain template and gain rank mxm. calculated, be kept in the storer, use during in order to processor calculating.
