Description
Technical field
The present invention relates to the picture processing technology field, be specifically related to a kind of photograph processing method and STB.
Background technology
The solution that present DTV is promoted the use of, normally the television set to existing reception analog signal is equipped with STB, but because in the set-top box environment, the font that browser is supported is limited, generally has only black matrix, has satisfied not demands of applications.Usually, each column title of the portal page of application all is to make on PC with artistic calligraphy earlier, forms a pictures, as the background picture of the application entrance page.
For example, be used for browser TV, that be installed on STB, generally do not have mouse and keyboard at present, most family has only a remote controller.So, generally be four buttons up and down to the operation on the page.Under the default situations, have four focuses in the page, but full page only has a firing line.Browser can respond user's button, and according to the relative position relation of focus in the page, moving focal point.
Consult Figure 1A, the effect that on PC, shows in the browser can be chosen the focus that needs through mouse or keyboard.But,, generally use the high bright demonstration current active focus of focus frame owing to there is not mouse at set-top box environment; And with first focus of the page as the acquiescence focus that gets into the page, so during the browser display page, effect is Figure 1B～1F; Get into from first focus, choose second focus to the right, choose the 4th focus downwards; Choose trifocal left, upwards choose first focus.
If above-mentioned focus example page need to adopt lishu, but set-top box environment does not have lishu.Need produce a background picture earlier, effect is following: consult Fig. 2 A.
Owing in the background picture needed Word message has been arranged, page body matter only needs the focus frame of a blank.Common way is that the Chinese words in the background picture of the application entrance page is replaced to a transparent picture; And the wide height of transparent picture is adjusted into corresponding area size in the background picture of the application entrance page; After the Chinese words of the background picture of the use transparent picture replacement application entrance page, the display effect of transparent picture and background picture is following: consult Fig. 2 B～2F.
The principle that the stack of transparent picture and background picture shows in the prior art is that transparent picture and background picture are decoded respectively; Generate data bitmap; The point that is about on transparent picture and the background picture is filled in the region of memory of display device; Transparent picture is filled into that the set of pairing pixel is exactly the data bitmap of transparent picture behind the region of memory of said display device, and background picture is filled into that the set of pairing pixel is exactly the data bitmap of background picture behind the region of memory of said display device.
Each pixel in the data bitmap has transparent, red, green and blue four kinds of color values.Because of the color value of all pixels on the data bitmap of transparent picture all is that full impregnated is bright, so the just content of background picture that shows on the display device.
Transparent picture of the prior art is identical with background picture when showing with the background picture stack; Also to decode; After decoding, to judge to the color value of each pixel in the data bitmap; If the result who judges is that the color value of this pixel is that full impregnated is bright, just do not show this transparent picture.If a transparent picture is used by many background pictures, this transparent picture will repeatedly be decoded, and this decoding is repeatedly judged repeatedly, has wasted great amount of time, has prolonged the display speed of background picture.
When Installed System Memory is not enough, can discharge the shared internal memory of data bitmap of picture.When Show Picture next time, again picture is decoded again, regenerate data bitmap.Releasing memory has guaranteed that system under the low-resource environment, still can Show Picture.But,, be the strategy that typically changes the space with the time so need pay time cost owing to need decoding again.
When the Installed System Memory wretched insufficiency, can further discharge the shared internal memory of picture initial data, said initial data is meant the data that system stored when Loading Image.When Show Picture next time, need reload picture, decoding with the longer time, is changed more space again.
