Bus Interface Unit S332: link to each other with described data storage cell, the view data that is used for being stored in data storage cell sends to the central processing unit of terminal by bus.
Elaborate below in conjunction with a pair of technical scheme of the present invention of embodiment:
In embodiment one, transmission and control device of high-frame-rate images of the present invention is used to receive the view data of 320 (H) x240 (V) form.If data storage cell can be stored 24 row view data, promptly getting frame per second when this format-pattern is interlacing when getting frame, the extraction that needs 5 times interruption just can be finished all 120 line data.
In conjunction with shown in Figure 1, described transmission and control device of high-frame-rate images comprises: image receiver module S11, image processing module S22, image sending module S33.
In the practical application, the image receiver module is that described transmission and control device of high-frame-rate images receives the view data of sending into this low and middle-end mobile device system.
As shown in Figure 2, be first two field picture and the second two field picture schematic diagram of importing transmission and control device of high-frame-rate images continuously.
Image processing module receives the view data of being sent into by described image receiver module, because the frame rate of viewdata signal surpasses the disposal ability that system supports view data, and surpass the frame rate that system can stablize smooth output image, so according to the configuration the frame per second of getting data in the field are selected, detailed process as shown in Figure 3:
The first two field picture F0 interrupts choosing label 1-47 totally 24 row odd-numbered line data for the first time;
The first two field picture F0 interrupts choosing label 49-95 totally 24 row odd-numbered line data for the second time;
The first two field picture F0 interrupts choosing label 97-143 totally 24 row odd-numbered line data for the third time;
The first two field picture F0 interrupts choosing label 145-181 totally 24 row odd-numbered line data at the 4th time;
The first two field picture F0 interrupts choosing label 183-239 totally 24 row odd-numbered line data at the 5th time;
First two field picture is extracted out 120 row odd-numbered line data, is stored in data storage cell successively, and outwards transmits by bus interface.The image that is presented on the display screen of low and middle-end mobile device system is identical with the view data that the image receiver module receives in odd-numbered line, even number behavior blank.
The second two field picture F1 interrupts choosing label 2-48 totally 24 row even number of lines certificates for the first time;
The second two field picture F1 interrupts choosing label 50-96 totally 24 row even number of lines certificates for the second time;
The second two field picture F1 interrupts choosing label 98-144 totally 24 row even number of lines certificates for the third time;
The second two field picture F1 interrupts choosing label 146-182 totally 24 row even number of lines certificates at the 4th time;
The second two field picture F1 interrupts choosing label 184-240 totally 24 row even number of lines certificates at the 5th time;
Second two field picture is extracted out 120 row even number of lines certificates, is stored in data storage cell successively, and outwards transmits by bus interface.The image that is presented on the display screen of low and middle-end mobile device system is identical with the view data that the image receiver module receives in even number line, odd number behavior blank.
Because of human eye has the image retention effect, F0 and F1 two two field pictures show by display screen at short notice fast, the image of the first two field picture F0 still is trapped in user's the eye, the blank of the first two field picture even number line has been filled up in the appearance of the second two field picture F1, and it seems that two continuous two field pictures just be combined into a complete image.
The frame per second of getting of dispensing unit configuration is to be provided with according to the disposal ability of system processor to view data, each system processor differs widely to the disposal ability of view data, when transmission and control device of high-frame-rate images of the present invention and method are applied on the low and middle-end equipment such as mobile phone or Portable, personal personal digital assistant device, get frame per second by change, view data is selected combination, effectively reduce the image transmission rate, make the data of input equipment reach the requirement that adapts to this device hardware, make the data of input terminal can reach the hardware requirement of this system of use, guarantee the viewing effect of user image.
View data is carried out the particular row data pick-up not only guarantee to adapt to the mobile terminal device hardware requirement, and fully consider the smooth degree of image from the human visual system aspect.Adopt the technical scheme of this reality invention can effectively improve the picture quality of demonstration and the smooth degree of broadcast.Bus interface is read selecteed data from data storage cell, and for it provides certain redundancy, it can not caused transmitting the leakage biography of data and losing because of unfavorable situation occurring.
Transmission and control device of high-frame-rate images of the present invention, listed utilization in specification and execution mode, it can be applied to various suitable the present invention's field fully, for those skilled in the art, can be easy to realize additional advantage and make amendment, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the present invention is not limited to specific details, representational device and the examples shown that illustrates here and describe.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
