Abstract
Provided is an image frame multiplication processing method based on a high-speed memory dynamic burst length. Two frames of effective image buffer areas are arranged in a high-speed memory, the high-speed memory is externally provided with a write-in port and a read-out port, and the write-in port and the read-out port further correspond to the two frames of effective image buffer areas respectively. The image information before frame multiplication is connected with the write-in port of the high-speed memory through an external buffer, and the image information after frame multiplication is connected with the read-out port of the high-speed memory through the external buffer. Frame multiplication of any integer multiple is carried out by the way of controlling the image data burst length of the write-in and read-out high-speed memory. By means of the image frame multiplication processing method based on the high-speed memory dynamic burst length, the frame rate improvement of any integer multiple can be effectively conducted, moreover, an image frame multiplication chase prevention algorithm is included, the problem that a picture includes two frames of images front and back is solved, image processing programming engineering using the algorithm can perfectly supply the needed frame rate to users.
Description
Technical field
The present invention relates to the technical field of video monitoring, is a kind of times frame processing method of image based on high-speed memory dynamic burst length specifically.
Background technology
Frame per second is the picture number that per second shows, frame per second directly affects the picture fluency, and to the picture fluency, be directly proportional: frame per second is larger, and picture is more smooth; Frame per second is less, and picture more has the sense of beating.
Along with the development of image processing techniques, various video formats all need to use the frame per second lift technique to the conversion of standard SMPTE video format and to the docking of display device.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of times frame processing method of image based on high-speed memory dynamic burst length.
The technical scheme that the present invention takes for the technical problem existed in the solution known technology is:
Image based on high-speed memory dynamic burst length times frame processing method of the present invention, two frame effective image buffering areas are set in high-speed memory, high-speed memory writes and reads two kinds of interfaces to being outside equipped with, and write and read interface respectively separately corresponding to above-mentioned two frame effective image buffer areas, image information before times frame is connected with the inbound port of writing of high-speed memory by the external cache device, image information after times frame is connected with the port of reading of high-speed memory by the external cache device, by control, write times frame that carries out the arbitrary integer multiple with the view data burst length of reading high-speed memory.
The present invention can also adopt following technical measures:
The corresponding connection of above-mentioned each effective image buffering area writes and reads interface.
In described two frame effective image buffer area A, B, the end address of the A field picture data of storing in the A buffering area is identical with the initial address of the B field picture data of B buffer area storage.
Advantage and good effect that the present invention has are:
Image based on high-speed memory dynamic burst length times frame processing method of the present invention, can effectively carry out arbitrary integer frame per second doubly and promote, and contain that image times frame is anti-catches up with algorithm, the problem of two two field pictures before and after can not occurring in a width picture to comprise.The image processing program project engineering of using this algorithm to carry out, can perfectly provide the user required frame per second.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of times frame processing method of the image based on high-speed memory dynamic burst length of the present invention.
