<embodiment>
One embodiment of the present of invention provides a kind of image processing method, as shown in Figure 1, comprising the following steps:
Firstly, being step S1100, the display parameters of image display are obtained, the display parameters include at least image
Show the display refresh mode of equipment.
The display parameters of image display are the system parameters of vision facilities, can be from what image display provided
Interface of uniting obtains.The display parameters of image display include at least the display refresh mode of vision facilities, i.e., image, which is shown, sets
The standby image data when performing image display refreshes the mode of display.For example, the display refresh mode of image display can
To be row data refresh mode or column data refresh mode, wherein corresponding row data refresh mode is that picture number is refreshed by row
According to being shown, corresponding column data refresh mode is shown by column refresh picture data.
The display parameters of image display can also include that other are relevant to the display function in image display
Parameter, for example, further including the resolution ratio and refresh rate of image display.
The form of image display be also possible to it is a variety of, as long as can make with the equipment of image display function
For image display, for example, image display is head-mounted display apparatus.
Step S1200 configures image source according to the display parameters, so that image source output meets the first of display parameters
Image.
Image display does not generate image usually, and the image of display both is from the image source of peripheral hardware (for example, passing through
The electronic equipment wirelessly or non-wirelessly connected), for example, image source is computer or mobile phone, by taking head-mounted display apparatus as an example, display
Image be usually the image that obtains after being connect with computer or mobile phone wireless.
And the image that image source provides may not meet the display refresh mode of image display, for example, image is shown
Equipment is column data refresh mode (or row data refresh mode), but the image that image source provides is only applicable to row Refresh Data mould
Formula (or column data refresh mode), in this case, it usually needs image rotation processing is done, for example, by applicable row Refresh Data
Image rotation be meet column data refreshing image, in the prior art, such rotation processing, it usually needs read it is whole
It is carried out after frame image, this means that the processing time at least needing a picture frame, it is however generally that, the duration of a picture frame
For a few tens of milliseconds (duration of specific picture frame is related with the format size of image), long processing delay is that human eye is distinguishable in this way
Other, when viewing image can be brought to continuously display Caton, causes undesirable usage experience.And in the present embodiment, pass through image
It shows that equipment configures image source according to the display parameters of itself, image output can be made to meet the first image of display parameters,
Thus without being handled again the image for not meeting display refresh mode, the processing delay that image is shown is reduced.Meanwhile this
In embodiment, image source can also be configured by display parameters and export the resolution ratio and refreshing that image meets image display
Rate avoids relevant resolution ratio and refresh rate matching treatment.
In one example, step S1200 is as shown in Fig. 2, include the following steps:
Step S1210 modifies the display identification data in described image source according to display parameters, so that described image source is aobvious
Show that mark data includes at least content corresponding with the display parameters.
The display identification data of image source is the internal indicator data relevant to display of image source, is generally comprised and image
Show relevant content of parameter, the image of image source output all needs to meet in the corresponding parameter for including in display identification data
Hold.In one example, the display identification data of image source is EDID.EDID is Extended Display
Identification Data (extending display identification data) is a kind of VESA standard data format, wherein containing almost institute
There is the universal description of display parameters.
The display identification data of image source is modified, such as the content that increase display parameters include in display identification data,
Or the corresponding parameter item content of modification display identification data makes content corresponding with display parameters consistent, can make figure
The display identification data of image source includes at least content corresponding with the display parameters of image display.
Described image source is written in the display identification data in described image source by step S1220, so that described image source exports
Meet the first image of the display parameters.
The display identification data of image source will not usually come into force after the modification as internal indicator data, need weight
New write-in image source makes the display identification data of modified image source come into force, and image source could be made to export the first image symbol
It closes the modified display presentation data and accordingly also complies with the display parameters of image display.
After step S1200, S1300 is entered step, the first image is received, is stored as the first corresponding figure
As data.
Step S1400, output to described image shows equipment after carrying out distortion processing to the first image data.
In general, image display can have different degrees of optical distortion when showing to image, this
Optical distortion is lost caused by the transillumination of optical lens inherent characteristic (convex lens convergence light, concavees lens divergent rays)
Very, usually the correction that distortion processing carries out optical distortion can be carried out using many algorithms in the prior art, so that defeated
Show that distortion of the image of equipment in display is removed to described image out.
It goes distortion processing process also different according to the process resource of the different consumption of algorithm and time, is provided in available processing
In the limited situation in source, step S1400 can be as shown in figure 3, include the following steps:
The first image data are divided into the first video data block of several specified sizes by step S1410.
The specified size for dividing image block, can be formulated according to available process resource, can also be according to other need
Ask specified, in one example, specifying size is the video data block of 30*30, and the image of a 1920*1080 can be divided into
2304 such sized images data blocks can make the process resource consumed in Distortion course be reduced to whole image of processing
The 0.4% of required resource.
Step S1420 reads each the first image data block, and goes to each the first image data block
Distortion processing obtains the second corresponding video data block respectively and stores；
In the situation that available process resource is limited, can partition image data into several video data blocks respectively into
Row goes distortion processing, can reduce the process resource for the treatment of process consumption in this way.For example, the first image of a 1920*1080
It can be divided into the first video data block of 2304 such 30*30 sizes, the processing consumed in Distortion course can be made
0.4% of resource needed for resource is reduced to whole image of processing.It, can also be with multiple to the when available process resource allows
One video data block carries out distortion processing parallel, reduces the time for going distortion processing process to consume.
Step S1430 reads several second video data blocks for meeting predetermined condition, and output is shown to described image to be set
It is standby.
To several first video data blocks that the first image data divides, distortion processing is carried out respectively, correspondingly, just
May not need after distortion processing is gone in whole the first image data completions just will treated corresponding the second picture number of whole
It exports according to block to image display, but during going distortion processing, several second images of predetermined condition will be met
Data block is exported to image display, further decreases the processing delay in image display process.
Wherein, the predetermined condition, can be determining according to the Special display demand that the first image is shown, can also basis
The display characteristic of image display determines, it is preferable that the predetermined condition is several second video data blocks composition
Image-region Pixel Dimensions, with described image show equipment on image show minimum pixel size it is identical.For example, figure
As showing the image display minimum pixel in equipment having a size of 1920*30, the size of the second video data block is 30*30, if through
The Pixel Dimensions and 1920*30 and image of the image-region of 64 the second video data blocks composition stored after past distortion processing
Show that minimum pixel size is identical, this can read this 64 second video data blocks and export to image display.
Also, the minimum pixel size that image is shown can be preset, but preferably, show equipment according to described image
Display refresh mode, the first image Pixel Dimensions and divide the first image specified size, determine described image
It shows minimum pixel size, determines that described image shows minimum pixel size.It is the first of 1920*1080 with a Pixel Dimensions
For image, it is assumed that the display refresh mode of image display is column data refreshing, and the first image data is divided into multiple 30*
30 the first video data block (accordingly, the Pixel Dimensions of the second video data block through past distortion processing are still 30*30),
Can then determine image show minimum pixel having a size of 30*1080, correspondingly, in this example, if image display
Display refresh mode be row Refresh Data, it is determined that image show minimum pixel having a size of 1920*30.
In addition, going the reading of distortion processing process and the second video data block output process can the first video data block
To carry out parallel, but practical the second video data block for reading output is to go distortion processing by corresponding first video data block completion
It obtains afterwards, in the output of these the second video data blocks, what is handled parallel is other first without going distortion processing
Image block can carry out additional control pipe in order to avoid carrying out the timing error occurred in the process parallel to the two processes
Reason, but accordingly additional process resource can be brought to consume.To avoid timing error and reducing process resource consumption, in an example
In, second figure can be calculated according to the initial memory address and preset offset address of second video data block
As address is read in the starting of data block.
Wherein, specific calculation may is that the starting of the second video data block is read when address is using cumulative mode
Taking address is that the initial memory address of the second video data block subtracts offset address；When address uses decreasing fashion, the second figure
The initial memory address that address is the second video data block, which is read, as the starting of data block adds offset address.Also, offset address
It can be preset according to the delay requirement of image, for example, reading speed is every millisecond of N1 unit address, the delay of image is needed
Asking is 5 milliseconds, then offset address is 5*N1.Offset address can also be according to the number for the second video data block that need to read output
And the processing delay of corresponding each first video data block of estimation is preset, for example, the processing delay estimated is 0.1
Millisecond, the number for the second video data block that need to be read are N2, and reading speed is every millisecond of N1 unit address, then offset address
For 0.1*N2*N1.
It calculates starting reading address according to aforesaid way to be read out the second video data block, it can be ensured that the second image
The starting of data reads the moment after the starting of the second video data block stores the moment, avoids the occurrence of timing error, and be not necessarily to
Additional control manages bring resource consumption.
