Description
Technical field
The invention belongs to multimedia technology field, relate in particular to a kind of LCD controller and image-scaling method.
Background technology
When on mobile device, carrying out the picture demonstration, use the amplification reduction capability of picture through regular meeting.Since at present the RGB selected for use of mobile device (Red Green Blue, RGB) the pattern screen is that a kind of real-time requires very high equipment, and LCD (Liquid Crystal Display, LCD) screen display needs lot of data to move.So in the system design of moving processor, transmission bandwidth is a very crucial problem.When particularly carrying out the image reduction operation, because the original image that needs to transmit will be bigger than the image data amount that needs show, so the transmission bandwidth that needs just requires strictness more.
In the design of mobile multi-media terminal hardware; Image zoom module in the LCD controller is crucial; Because performance that it is determining whole system and final display effect, it efficiently and fast be the whether successful key factor of decision whole system.
Most mobile hand-held device has adopted the YUV420 form to deposit video data, but all carries out data processing according to the YUV444 form usually in each image processing module inside.Fig. 1 shows the YUV420 form, and Fig. 2 shows the YUV444 form.Following brief account existing technical scheme is how to realize image zoom.
The convergent-divergent of image all is to adopt the bilinear interpolation algorithm usually, and the pixel that just new interpolation is come out is to be got by two adjacent original pixels point processings.Fig. 3 shows bilinear interpolation algorithm quick-reading flow sheets in the prior art.The concrete implementation method of bilinear interpolation algorithm is, at first row done horizontal bilinear interpolation, and original image is 4x2, totally two row just, 4 pixels of every row.Do horizontal bilinear interpolation to the data of two row respectively earlier, and then do vertical bilinear interpolation to this two row and handle, promptly corresponding pixel is done interpolation with same algorithm in two row, calculates pixel new on the column direction, obtains the line data of target 2x1 at last.
Fig. 4 is a convergent-divergent control system sketch map in the prior art.We can see from block diagram; The view data of the YUV420 form of external storage is downloaded to respectively in the corresponding buffering area of LCD module, is spliced into the data of YUV444 form then; Deliver to Zoom module to these view data again and carry out the convergent-divergent computing; All computings all are that unit carries out with the pixel, and one of them pixel comprises YUV each 8 bits, totally 24 Bit datas.At first carry out horizontal scaling; The data line of handling well all deposits in the row buffer, and then fetches in the data of second row to do horizontal scaling, and then need to judge whether the delegation with temporary before do vertical interpolation; Just insert the delegation that makes new advances if desired, do not need just to throw away.Loop computation gets target image to the end like this, and each module that sends the back level again to is carried out subsequent treatment.
In the prior art, simply generally be the data processing that the data splicing that the YUV420 form is imported in the outside is become the YUV444 form in order to control.Though this control method is simple, the convergent-divergent arithmetic element is that the unit carries out computing with the pixel, and external data is the YUV420 form; The U, the V signal that also just mean adjacent odd-numbered line and even number line are identical, and in existing technical scheme, horizontal scaling is good when first line data; After depositing in the row buffer; All data of second row still will be all (Direct Memory Access DMA) reads into, and it is done horizontal bilinear interpolation processing through the direct memory access module; Do vertical bilinear interpolation with first row again and handle, obtain the target line data.And in fact second row to have only the Y data be different with first row, but because arithmetic element all is based on pixel, therefore must also walk all flow processs to UV again one time with the be stitched together pixel of a completion of formation of Y.So not only waste bandwidth, and increased unnecessary power consumption.
Summary of the invention
Embodiment of the invention technical problem to be solved is to provide a kind of LCD controller and image-scaling method; So that in to bandwidth requirement hard real time property system, handling process through optimizing the image zoom module and control strategy reduce system bandwidth and take and improve the calculation process method of velocity.
For solving the problems of the technologies described above, the embodiment of the invention provides a kind of LCD controller, and it comprises direct memory access module and back level module, also comprises image zoom module and format converting module.Wherein the image zoom module comprises horizontal bilinear interpolation unit and vertical bilinear interpolation unit.Horizontal bilinear interpolation unit is made up of the horizontal bilinear interpolation of Y unit, U horizontal bilinear interpolation unit and the horizontal bilinear interpolation of V unit.Vertically the bilinear interpolation unit is made up of the vertical bilinear interpolation of Y unit, U vertical bilinear interpolation unit and the vertical bilinear interpolation of V unit.The image zoom module is accomplished image zoom and is obtained the target line data that form is YUV420, and said target line data are sent to format converting module through DMA reads image data from external memory storage.Format converting module will become the YUV444 form from the target line data splicing of image zoom module, and send to back level module.
Another purpose of the embodiment of the invention is to provide a kind of image-scaling method, may further comprise the steps:
