Be described in detail below in conjunction with the embodiment of accompanying drawing to image translation update displayed method of the present invention.
Referring to shown in Figure 1, Fig. 1 is the image translation update displayed method flow diagram of an embodiment, comprises the steps:
Step S10: when image translation upgrades, from the first internal memory, obtain the common image data, and it is copied in the second internal memory; Wherein, described the first internal memory is used for preserving complete view data, and described common image data are the view data of same area before and after image translation upgrades in the first internal memory.
In this step, mainly be the view data of obtaining the intersecting area on the image coordinate of translation before and after upgrading, it is copied in the second internal memory.
In one embodiment, can comprise the steps:
Step S101 is according to the image-region coordinate after the described span computed image of the image-region coordinate translation renewal before the image translation renewal.
Concrete, obtain the span that image translation upgrades the pixel translation, determine the image-region coordinate before image translation upgrades, add at this image-region coordinate the span of translation namely to obtain the image-region coordinate after image translation upgrades.
Step S102, the intersection graph of the image-region coordinate after the image-region before the image-region coordinate Calculation image translation renewal according to the image-region coordinate before the described renewal and after upgrading and image translation upgrade is as area coordinate.
Concrete, according to the image-region coordinate after the image-region coordinate before the translation renewal and the translation renewal, judge the image range of two area coordinates, get the common factor part of image range, obtain intersection graph as area coordinate.
Step S103 extracts corresponding common image data according to described intersection graph as area coordinate from the first internal memory.
Concrete, as area coordinate, from the first internal memory, read this intersection graph as the view data of area coordinate according to intersection graph, then it is copied in the second internal memory.
Because view data is direct copying from internal memory, speed is fast, has improved the efficient of translation update displayed.
Step S20: the modified-image data are drawn to the 3rd internal memory; Wherein, described modified-image data are the view data of region of variation before and after image translation upgrades in the first internal memory.
In this step, mainly be that the drawing image translation is upgraded in view data to the three internal memories that change, thereby reduce the processing procedure that the view data of front and back same area is upgraded in the drawing image translation.
In one embodiment, can comprise the steps:
Step S201, the modified-image area coordinate after the computed image translation is upgraded.
Concrete, the image-region coordinate according to after the translation renewal of aforementioned calculating deducts intersection graph as area coordinate, obtains the modified-image area coordinate after translation is upgraded.
Step S202 reads corresponding modified-image data according to described modified-image area coordinate from storage medium.
Concrete, according to the modified-image area coordinate, read view data in this modified-image area coordinate pixel coverage from storage mediums such as hard disk, disks.
Step S203 draws described modified-image data in described the 3rd internal memory.
Concrete, the view data in the modified-image area coordinate pixel coverage is plotted in the 3rd internal memory, owing to need not to draw the common image data, reduced the process of drawing, improve render speed and efficient.
Step S30: the view data in described the second internal memory and the 3rd internal memory is copied in described the first internal memory.
In this step, be the view data regrouping process, the view data that is about in the second internal memory and the 3rd internal memory concerns by its coordinate, is copied to successively in the first internal memory, obtains the view data after complete translation is upgraded.
Step S40: the view data in described the first internal memory is shown.
In this step, mainly be the process that realizes that the rear complete view data of translation renewal shows in display device.
In one embodiment, at first the view data of the first internal memory is copied on the dc of interface; Then the view data on the described interface dc is shown.
