, can be using table tennis in order to not influence image to be stored in internal memory or DDR efficiency in a kind of optional scheme Buffer mode carries out data buffer storage, and pending view data after combination is stored in table tennis buffer, and is led to Cross table tennis buffer to export pending view data into follow-up processing module, so as to realize to pending picture number According to the purpose handled.

Fig. 4 is a kind of flow chart of the processing method of optional view data according to embodiments of the present invention, with reference to A kind of preferred embodiment of the invention is described in detail Fig. 4, as shown in figure 4, this method may include steps of：

Step S41, the video and picture signal of collection are placed into buffer and cached.

Alternatively, in order to not influence image to store the efficiency to internal memory or DDR, carried out by the way of table tennis buffer Data buffer storage.

Step S42, by the digital independent of buffer memory storages, and is written in internal memory or DDR.

Alternatively, when data are read from buffer, according to characteristics of image, choose a kind of preferable control algolithm and carry out logarithm According to being handled, the selection of the control algolithm depends on three factors, specific as follows：First factor is the tool in input picture source Body resolution ratio, different resolution ratio can select different control algolithms；Second factor is the elementary cell of control algolithm, control Unit processed can select a line for image, can also select 1/2,1/4,1/8 ... for image a line, different selection institutes Need the flag_ram of consumption resource different, the amount of bandwidth to reduction internal memory or DDR is also different, and flag_ram Resource occupation it is bigger, reduction internal memory or DDR bandwidth it is more obvious；3rd factor is the manner of comparison of elementary cell, can be with Individually selection elementary cell carries out lateral comparison with adjacent elementary cell, can also individually select elementary cell and adjacent base This unit carries out longitudinal comparison, can also select elementary cell with adjacent elementary cell while carrying out horizontal, longitudinal comparison, work as horizontal stroke To or only longitudinal comparison when, flag_ram bit wide selection be 1bit, when transverse direction+longitudinal comparison, flag_ram position Width selection is 2bit, and RAM resources, which increase, to be twice, but its bandwidth to reduction internal memory or DDR also has income by about one time.

For example, for 1080p image, the data for choosing 1920 YUV or RGB of a line are basic control unit.One The first row of two field picture is bound in write-in internal memory or DDR, and produces flag and be masked as 0, and mark is stored to flag_ram In.During the first row write operation, the second row data in table tennis buffer are read, are compared with the first row data, such as Really the second row data are identical with the first row data correspondence position comparing, then produce flag and be masked as 1, mark is stored Into flag_ram, and the data of the second row are controlled without write operation；If the second row data are corresponding with the first row data Position data comparison is incomplete same, then produces flag and be masked as 0, mark is stored into flag_ram, and control second Capable data proceed write operation, and the second row data are write in internal memory or DDR；The like push away at the data of other rows Reason, is completed until a complete frame is operated.

Step S43, data are read from internal memory or DDR.

Alternatively, when reading data from internal memory or DDR, the corresponding row of correspondence frame is read first from flag_ram Flag indicates.The first row flag marks one per frame are set to 0, it is necessary to read the data of the first row from DDR；Starting the second row Read operation before, read the flag marks of the second row of correspondence frame in flag_ram, if this is masked as 0, continue to start the The read operation of two rows；If this is masked as 1, the data of the second row are not read, it is directly that the data duplication portion of the first row is defeated Go out；The like other rows data processing, completed until a complete frame is operated.

Step S44, the data of reading are output to other processing modules by buffer controls.

By above-mentioned steps, recessive information can be extracted, and control by recessive information by analyzing feature of image DDR storage and reading, to reduce DDR bandwidth, and due to extracting the recessive character of image, it is only necessary to increase less place Logic is managed, compared with currently existing scheme, area and cost is reduced, and the delay for storing and handling without image.
