Description
Technical field
The present invention is relevant to a kind of image processor, refers to a kind of image processor that is used for field emission displays especially.
Background technology
Display in the past all is to adopt laterally to place, and promptly is wider width and the less mode of length is placed.But, at present increasing display adopts directly to placement, with display is to present long image to the benefit of placing directly, and can not cause image to be cut because of insufficient height, for example utilize directly can be complete to the display of placing the image that presents the human body whole body, and the display of in the past laterally placing can only present the upper part of the body image of human body, so directly adopted by increasing society to the display of placing.
See also Fig. 1 and Fig. 2, Figure 1 shows that the display of horizontal placement carries out the schematic diagram of image scan.Figure 2 shows that the schematic diagram that directly carries out image scan to the display of placing.If display is changed into directly when placing by horizontal placement, upright image as shown in Figure 1 revolves the image that turn 90 degrees by directly becoming to be illustrated in figure 2 as to the image of placing that display presented, image data must be carried out Coordinate Conversion under this kind situation handles, could will revolve the image adjustment that turn 90 degrees as shown in Figure 2 and return upright image, and be play.
When general image playing system is wanted playing video; usually image processor can be seen through and Synchronous Dynamic Random Access Memory (Synchronous DynamicRandom Memory Access will be stored in; SDRAM) after image frame is handled in regular turn, again the image frame of handling is stored back Synchronous Dynamic Random Access Memory.Image processor carries out the mode of image processing just as shown in Figure 1, first columns by image frame is handled towards the mode one row one leu preface of arrow according to beginning, until the data of last row are all processed finish after, deposit the data of handling in memory again, carry out the output of rear end and handle, last transmission display device is play.
Yet if image playing system adopts directly when the display placed, image processor carries out image frame can suffer from certain difficulty.Because the characteristic of general Synchronous Dynamic Random Access Memory is very fast to the data processing of same delegation (Row), and slower to the data processing speed of different rows.Therefore when display during directly to placement, image processor carries out the image frame processing and can become memory consecutive access (direction of arrow as shown in Figure 2) longitudinally, promptly be that above-mentioned data to different rows are handled, remove to handle image frame so must spend the long time, and cause image to play slack problem, this kind phenomenon has necessity of its improvement for stressing high-quality consumption demand at present.
Therefore, be necessary to propose a kind of image processor and image playing system really, can effectively reduce the time of image processing, to promote image processing efficiency.
