[embodiment]
Below in conjunction with accompanying drawing the utility model embodiment is described further.
As shown in Figure 1, adjust automatically among the embodiment of device of input picture resolution at the utility model, its self-adjusting method comprises the steps:
S11 obtains input image data and resolution thereof: in this step, data are read in place by image data storage or generation, at this moment, what read in is the data of a two field picture, be in order to obtain the parameter of image comprehensively on the one hand, the parameters such as sum that comprise resolution, pixel also can temporarily leave this frame image data in the storer on the other hand, and convenient follow-up handling procedure calls.Above-mentioned image comprises by the memory device stores in the external world image in this device.
S12 obtains terminal display resolution: in this device, comprised a display screen that is used for display image, this display screen has a resolution, and this monitor resolution is the demonstration bottleneck of whole device.Usually, be exactly the display resolution that this monitor resolution has determined whole device.For this device, as long as it is just passable that the resolution of view data of input is not less than aforementioned display device resolution, too high-resolution image can not demonstrate its details equally on above-mentioned display screen, on the contrary, its a large amount of details has increased its file content, take the storage space of this device, make this device in identical storage space, can only store less picture, make that the utilization rate of its storage space is lower.Therefore, as long as the image resolution ratio of input is not less than aforementioned display device resolution, aforementioned display device resolution can be used as the standard of the resolution of above-mentioned terminal input picture.In this step, be exactly to obtain aforementioned display device resolution by central controller.
The resolution of the more above-mentioned input image data of S13 and the resolution of terminal display, needing to obtain the number of pixels of compression: pass through above-mentioned steps, obtain the resolution and the terminal display resolution of input image data, in this step, more above-mentioned two resolution, the concrete number of pixels that draws total number of pixels of needing compression and need compress specific to every row in every frame and every row, for example, the resolution of the image of input is 3000 * 1000, and monitor resolution is 800 * 600, just can draw altogether what pixels needs compress according to these two data, wherein, comprise needing how many row of compression and how many row altogether.
S14 calls in buffer memory simultaneously with the pixel of same position in several capable pixels in the input picture: in this step, the data of same number of columns in the several line data in the view data of above-mentioned input are called in memory buffer, prepare to begin to handle (compression) these data.Owing to needing altogether in above-mentioned steps, to have obtained the pixel, row and the columns that compress, and a part that is actually in the two field picture of calling in this step (is actually image is divided into limited piece, access one handles at every turn soon, there is a proportionate relationship between piece and the integral image), therefore, can obtain the concrete quantity of input image data need compress in this step pixel, row and columns by the parameter correspondence that entire image need be compressed.In the present embodiment, when calling in above-mentioned view data, obtain above-mentioned pixel, row and columns.
S15 scans these pixels, finds out wherein pure color or the highest pixel of tone purity: for the data of calling in, scan wherein each pixel, in these pixels, analyze and find the wherein pixel or the purest point of its colourity of pure color.Because the diversity of image, thus may be in the pixel of the view data of input, may there be pure color, at this moment, the target of searching is exactly the purest pixel of colourity.
S16 decision is current to need the deletion amount of pixels and with the horizontal or vertical adjacent pixels point symmetry deletion of described demarcation pixel: with the above-mentioned pixel that finds be the center, according to above-mentioned line number and the columns that needing to obtain compression, delete the row or column adjacent symmetrically with this pure color pixel, if so-called symmetry has been deleted a row pixel on the left side of this pure color pixel horizontal level in fact exactly, then also require at its right deletion one row; If deleted a row pixel, then also require at its following deletion one row in the top of this pure color pixel upright position.
Does S17 handle a two field picture? judge whether to finish the processing of a two field picture, as finishing, execution in step S18, as not finishing the processing of a two field picture, jump to step S14, call in the another part (piece) in the input picture, the adjacent part (piece) of normally above-mentioned processing section (piece) begins it is carried out the processing of step S14 to S17.
View data after S18 will handle is kept in the storer, and on display, show: in this step, an above-mentioned two field picture is finished dealing with according to exploration on display resolution ratio, obtain meeting the image file of aforementioned display device resolution, this file both can make full use of display, and its data volume is also less, and helping preserving in the finite storage space of this digital terminal all may many picture file.In this step, above-mentioned file is kept in the storer, simultaneously, on the display screen of this device, shows this document.
