Abstract

The invention relates to a gradient mirror processing method for a digital image, which is used for adjusting the brightness difference in the digital image through a digital camera. The gradient mirror processing method comprises the following steps: an image boundary of the digital image is determined according to the image difference conditions in one digital image; and a gradient image layer is used in the digital image along the vertical direction of the image boundary to adjust the brightness difference in the digital image. The corresponding image boundary is generated according to the image difference conditions in the digital image, and the gradient mirror processing is performed to the digital image according to the image boundary so as to adjust the brightness among the different areas for the digital image. Therefore, the digital image is more realistic for the shooting scenes.

Description

The method for processing gradual layered mirror of digitized video
Technical field
The present invention relates to a kind of processing method, particularly relate to a kind of automatic method for processing gradual layered mirror digitized video to digitized video.
Background technology
Along with the fast development of digital camera, make more and more people also drop into the ranks of photography.But digital camera can be because the photometry mechanism of digital camera has influence on the display result of digitized video when taking.When if the brightness in the digitized video is excessive, though the captured digitized video that comes out is easy to cause the shooting body brightness normal, background but is that a slice is white.So many users can be sent to captured photo in the personal computer, utilize relevant software to carry out follow-up processing again.
Just the handling procedure of some back systems is adjusted the user for just having crossed the threshold such as (contrast) or color curve adjustment (color curve modify) as contrast, and its operating process is to have certain operation easier to exist.In image processing software, in order to simplify problem, so in many softwares, all can utilize the mode of figure layer (layer) to handle the demonstration problem of the zones of different in the digitized video 100 to the difficult adjustment of digitized video 100.Please refer to shown in Figure 1ly, it is a digitized video schematic diagram of applying mechanically gradually layer figure layer.For example, shown in Figure 1 will choose a part block as pending figure layer in the digitized video 100, and the outward appearance of figure layer is to determine according to the scope that user institute desire is handled.For instance, the figure layer can be rectangle, square, circle or irregular zone.If will carry out gradually layer processing to the color in the figure layer, then from the figure layer, select first color and second color.And the designated color direction that changes of layer gradually, gradually layer figure layer 110 can produce accordingly gradually layer figure layer 110 according to first color, second color and a layer direction gradually.At last, the gradually layer figure layer 110 that is produced is applied mechanically to the zone that digitized video 100 is selected, and makes digitized video 100 can more meet the original appearance of photographed scene.
But this can only handle in the postposition of the enterprising line number word of personal computer image 100, can't be real-time just handle instantly taking.When the user goes back to handle this digital image 100 by the time, often because the time of a specified duration excessively, so forget scene when taking pictures at that time.

Embodiment
The present invention is applied to the brightness adjustment between zones of different in the digitized video, makes the picture of digitized video present and can more meet the situation of photographed scene at that time.Please refer to shown in Figure 2ly, it is an operation workflow schematic diagram of the present invention.At the method for processing gradual layered mirror of digitized video of the present invention, comprise the following steps: step S210, according to the image difference condition in the digitized video, make video capturing device in order to determine the image boundary of digitized video.The image difference condition is to determine according to the color distortion in the digitized video, brightness or contrast.
Step S220, along with the vertical direction of image boundary gradually layer figure layer (mask) apply mechanically to digitized video, adjust the brightness of the figure layer appointed area in the digitized video, and show by a layer mode gradually, to reduce the vestige that the back system is handled, make image can present amended result naturally.Gradually layer figure layer is in the present invention handled in order to the gradually layer mirror that different zones is carried out brightness.Please be in addition with reference to shown in figure 3a and Fig. 3 b, it is respectively image boundary and layer direction schematic diagram gradually and applies mechanically the gradually digitized video schematic diagram of layer figure layer.Dotted line in Fig. 3 a is the image boundary 310 that step S210 is determined.
What the depth in Fig. 3 b changed representative is the gradually layer direction of gradually 320 pairs of brightness of layer figure layer.Gradually layer figure layer 320 can be rectangle, square, circle or irregular zone.Decision gradually layer figure layer 320 behind the position on the digitized video 300, and digitized video 300 is carried out the gradually processing of layer according to the resulting gradually layer of step S220 direction.
According to the gradually processing method of layer of the present invention, can be applied among several embodiment of the following stated.
A. a preferred embodiment of the present invention:
In this preferred embodiment according to the area ratio of the first image block and the second image block 430 and image information separately, in order to decision gradually gradually the layer range size and the ratio of layer figure layer 320.And please refer to shown in Fig. 4 a and Fig. 4 b, its gradually layer figure layer that is respectively another preferred embodiment is implemented schematic diagram.
At first, according to the resulting image boundary 310 of step S210, digitized video 300 is divided into the first image block 420 and the second image block 430.Then, in first imagery zone, select first image information; In addition, select second image information from second imagery zone.First image information and second image information can be color, brightness or contrast.Make that according to different treatment situations gradually layer direction can be by the first image block 420 toward the second image block 430 or the second image block, the 430 past first image blocks 420.Also can determine its gradually size of stratum proportion according to different treatment situations.
If the area of the first image block 420 will be greater than the second image block 430 for the gradually layer scope in the first image block 420 during greater than the second image block 430.So, can be so that digitized video 300 can visually have more level and smooth demonstration after gradually layer mirror handled.
The present invention produces corresponding image boundary 310 according to the image difference condition in the digitized video 300.And handle according to the gradually layer mirror that image boundary 310 carries out digitized video 300, so as to adjusting the brightness adjustment between digitized video 300 zoness of different.Make digitized video 300 can more meet the actual state of photographed scene.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of claim of the present invention.
