Image sending module S33, the odd-numbered line data of an extraction and the even number line data combination and the transmission of another extraction in the continuous two field picture of view data that is used for interlacing is extracted.
Corresponding image processing module S22 specifically can comprise:
Data chooser module S221, the line data of the view data that is used for said image receiver module is received carry out interlacing and extract;
Data output sub-module S222, the image data transmission of the particular row that is used for said data chooser module is extracted is to the image sending module.
Corresponding data Executive Module S33 specifically can comprise:
Storage subelement S331 is used to preserve the view data of the particular row that the interlacing from the data output sub-module extracts;
EBI subelement S332 is used for the data that are stored in the storage submodule are sent to system processor through bus.
Wherein, corresponding storage submodule comprises at least a among RAM, FRAM, DRAM, SRAM or the SDRAM.
In this embodiment, corresponding image frame rate transmission control unit is used to receive the view data of 320 (H) x240 (V) form.The tentation data memory cell can be stored 24 row view data, promptly when this format-pattern is got frame by interlacing, need interrupt accomplishing the extraction of all 120 line data for 5 times.
In conjunction with shown in Figure 1, said image frame rate transmission control unit comprises: image receiver module S11, image processing module S22, image sending module S33.
In the practical application, image receiver module S11 is that said image frame rate transmission control unit 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 sketch map of continuous input picture frame rate transmission control unit.
Image processing module S22 receives the view data of being sent into by said image receiver module S11; 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 the mode according to interlacing is extracted is selected data in the field, detailed process is 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 120 row odd-numbered line data, is stored in storage submodule S331 successively, and outwards transmits through EBI.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, and the even number behavior is blank.
The second two field picture F1 interrupts choosing label 2-48 totally 24 row even number of lines certificates for the first time;
