A kind of TV picture processing method
Technical field
The present invention relates to TV tech, particularly a kind of digitalized processing method of television image.
Background technology
Along with the development of Display Technique, and people's growth in the living standard, various panel TV sets increase day by day as the purchase volume of LCD, PDP TV etc.People's taste has also turned to personalized, fashion-orientation by popular gradually, more pays attention to the performance oneself, shows individual character, and is especially also more and more fastidious to the requirement of domestic environment.Because it is in light weight that panel TV has, the characteristics of slim body, panel TV, particularly LCD, PDP television set have been not only traditional audio-video terminal, and have become to intersperse an ornament in room.
Will be with television set as an ornament, the common way of prior art is that TV is embedded among the good picture frame of finishing, realizes the decorative effect of television set.The shortcoming of this technology is to need to make picture frame television set is decorated, and has increased the use cost of television set; On the other hand, finish in case decorate, its picture frame style is difficult to change the decorative effect dullness.
Summary of the invention
Technical problem to be solved by this invention just provides and a kind of multiple picture frame is stored in television set inside, can call different picture frames as required, embeds the method that picture shows.
The present invention solves the problems of the technologies described above, and the technical scheme of employing is that a kind of TV picture processing method comprises the steps:
A. select the picture frame picture, the picture of selecting is carried out digitized processing;
B. in the digital signal embedding program of the picture frame picture that will obtain by above-mentioned steps, be stored in the television memory;
C. the picture frame that superposes on the television set picture displayed embeds in the picture frame picture, forms the picture of band picture frame;
Among the described step c, the television set picture displayed is the picture that is stored in the television memory;
Described television set is the Card Reader television set;
Among the described step c, the picture on the storage card that the television set picture displayed is with television set is connected;
Described television set is a panel TV set;
Described panel TV set is LCD television set, PDP television set, LED television set or OLD television set;
The invention has the beneficial effects as follows, utilize Digital Signal Processing, television set brand new concept and intension have been given, the all functions that not only have conventional television, and have a various personalized picture frame decoration functions, can represent various picture frame decorative effects in conjunction with different household styles, and with low cost.The more important thing is and realize this picture frame display effect, do not need the user to increase any cost, only need remote controller or button by television set, the picture frame picture that calls in the television memory can be realized.
Description of drawings
Fig. 1 is the program flow diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.
Technical scheme of the present invention, with various picture frame pictures, pass through digitized processing, be stored in the television memory, when the data in calling memory show, handle by internal processes, picture frame superposes on picture displayed, during the picture of these picture frames that superposeed of screen display, television set resembles the decoration painting of a width of cloth through mounting, plays the effect of decoration.
Embodiment
Fig. 1 shows picture processing method program flow diagram of the present invention.
Select one 1280 * 1024, the jpeg format picture frame picture less than 60k is converted in the hexadecimal data embedding program.When program code was burnt to memory, the picture frame picture also was written to wherein in the mode of code.After DPF powers on start, be stored in the picture frame pictorial information among the flash, be sent to the zone that the definition among the SDRAM is finished by DMA, simultaneously the relevant register of main program initialization.When the user opened the picture frame function, user's instruction was passed through I from main frame
2The C bus passes to and is sent to the DPF module; After receiving the instruction of main frame, the fixed area of picture frame pictorial information from SRAM passes to the display buffer zone (displaybuffer) among the SRAM, and shows; When the user cancels picture frame, receive instruction back DPF module the picture frame information in displaybuffer is removed, thus the cancellation picture frame.
Adopt method of the present invention, the picture frame picture of different artistic style can be stored in the television memory, simultaneously, the user uses for convenience, can also store some images in the memory and select for the user.The user can call the picture frame of different-style, thereby produce colourful decorative effect according to the picture of selecting.Can show the so-called Card Reader television set of card image such as CF card, SD, MS card for those, the user can also pass through program, calls the image in the storage card, it is embedded in the selected picture frame show.
Technical scheme of the present invention is specially adapted to panel TV sets such as LCD television set, PDP television set, LED television set, OLD television set.
