Description of drawings
Fig. 1 is the theory diagram of display device of the present invention.
Fig. 2 is the flow chart that new start-up picture is set of the present invention.
Embodiment is described in further details the present invention below in conjunction with the drawings and specific embodiments.
The making of the start-up picture of current various display devices all is that picture or text conversion are become data, with code, deposit memory (normally FLASH memory) in, when start-up picture will be shown, again data are called in the video memory of OSD module, then display frame.
DDR and high performance ROM provide the possibility that realizes in the storage of catching that is applied as the video pictures signal of TV and field of display.Use very widely DDR in fields such as displays, be commonly used to store the image of input signal, video memory as the OSD module, some TV, display etc. also are loaded into the code among the ROM (such as the FLASH memory) among the DDR, CPU is directly from the DDR fetching, to improve the execution efficient of whole system.It also is increasingly extensive that high performance ROM (such as the FLASH memory) uses, and particularly the FLASH memory has improved memory space and maximum erasing times for ROM, and the byte number that has also reduced simultaneously minimum erase block has reduced cost.
The theory diagram of display of the present invention as shown in Figure 1, comprise central processor CPU, memory DDR, display screen, image processing ics and FLASH memory, CPU control storage DDR, display screen, image processing ics and the co-ordination of FLASH memory, and with DDR, FLASH memory and image processing ics swap data.CPU also accepts the control signal from the display device user.
The present invention realizes easily, theoretically, the image processing ics MSTAR289 of the MSTAR research and development in Taiwan, can realize this function on the image processing ics LX68 of the safe ancient cooking vessel research and development of the U.S., LX68 particularly, its image processing part can be chosen as 8bit or 10bit, the OSD module section also is 8bit, do not need to carry out the conversion of figure place, in addition, after LX68 catches the video image source, can come control store at DDR the inside data format (YUV or RGB), like this by the ICSC color matrix, do not need color data is changed yet, therefore, only need to increase the size of ROM (for example FLASH memory), the image that assurance is caught can be stored and get final product.
The flow chart that new start-up picture is set of the present invention as shown in Figure 2, when the user need to change start-up picture:
1: the user selects whether to enter start-up picture crawl by remote controller or button in custom menu, selects no, then end, selection is to enter step 2.
2: at first enter video crawl function.CPU sends data to image processing ics, allows its video or picture signal (normally take frame as unit) of stopping to catch write DDR, prevents that new pictorial data from refreshing the image data information that the user likes.
More than 1,2 step be exactly the function that TV and display etc. often have: static or quiet frame.
3: after executing for 2 steps, prompting user, whether crawl is finished, need to preserve, if user selection needs to preserve, software then enters preservation mode.If the user selection cancellation then sends data to image processing ics, allow it continue lock-on signal, recover normal operation.
4: after entering preservation mode, according to the functional characteristic of image processing ics, judge whether the pictorial data of crawl is consistent with the OSD module of image processing ics, if consistent, then directly enter into step 6, inconsistent, then enter step 5, carry out data transaction.
5: definite address realm and the data structure of frame in DDR that will catch for example is yuv format or rgb format, is 4:4:4 form or 4:2:2 form, is 10bit or 8bit etc.
Carry out the data format that data transaction becomes the OSD module to support these data transaction.At present, most of image processing ics crawls and the pictorial data that is stored among the DDR are Y, U, V format, be convenient to like this processing of brightness and colourity, the data great majority are 8bit, also have some only a fews high-end image processing ics be 10bit, 12bit etc., and the OSD module is 4bit in the image processing ics of some low sides, if 4bit, the start-up picture of then preserving can show at most 16 rank colors, poor effect, do not have much practical significances, the image processing ics of some middle and high ends is 8bit basically, if the pictorial data of crawl also is 8bit, just do not needed data bit transition, if 10bit, 12bit then can take certain methods to carry out data bit transition, such as 10bit, can take down low 2, allow it become 8bit, 12bit, take down low 4, allow it become 8bit.The data format that the OSD module engine of most image processing icses is supported is R, G, the B form, some is Y, U, V format, also can support for some two kinds, if the pixel format that OSD module engine is supported is R, G, the words of B form, then to carry out pixel format conversion, the execution speed of CPU has just been had certain requirement, present, what most of TVs used is 8,16 CPU, performance may not satisfy the requirement of data transaction, and what have also that some high-end TVs use is that 32 CPU is (such as the CT of Konka, DT series), its performance can realize above-mentioned data transaction fully.It seems from the 5th step, for the designer, the realization display device is arbitrarily changed the start-up picture function and is selected suitable image processing ics, very crucial, if image data format and the OSD module engine of crawl do not mate, then can bring the increase of hardware cost, software performance is unstable, spended time is long, the shortcomings such as display effect distortion.
6: the data communication device after will changing is crossed the mode of writing ROM, join the ROM fixed allocation to the address area of start-up picture, because different signal, effectively picture element is different in DDR, when the data of image are caught in storage, must store simultaneously the effective pixel of catching image and count, these data can be stored among the EEROM of display screen or directly are stored in the FLASH memory with some menu setting parameters.
7: the renewal of prompting user start-up picture finishes, and restarts TV.
8: restart TV, CPU can be according to the effective pixel point of new start-up picture after the initialization system setting, by the OSD module, the position of start-up picture is set, and will be stored in the data of the start-up picture among the ROM, import in the video memory of OSD module, show start-up picture.
