In disclosure scheme, the region that is blocked is carried out repair process it is to be understood that determine the color value of each pixel that the region that is blocked includes respectively.
After getting pending region, it is possible to first determine the central pixel point in pending region, and then utilize the color value of the pixel not being blocked, it is determined that go out the color value of central pixel point.
In a kind of possible embodiment, it is possible to the pixel being never blocked is chosen standby pixel; And the average of the color value by standby pixel, it is determined that centered by the color value of pixel. In conjunction with concrete application, it is possible to all pixels not being blocked are chosen for standby pixel; Or, it is also possible to randomly selecting the standby pixel of predetermined number from all pixels not being blocked, this can not be limited by disclosure embodiment.
The disclosure is when the color value utilizing standby pixel determines the color value of central pixel point, it is possible to calculate the average of the color value of all standby pixels, and using this average color value as central pixel point; Or, it is possible to the color value arranged in sequence to all standby pixels, and using the median color value as central pixel point; Or, it is possible to add up the color value of all standby pixels, will appear from the number of times maximum color value color value as central pixel point. The scheme of the disclosure embodiment color value to determining central pixel point can not limit.
In step 203, the color value of the pixel not being blocked described in utilization and the color value of described central pixel point, it is determined that the color value of the residual pixel point in described pending region.
Such as introduction made above, the region that is blocked is carried out repair process by disclosure scheme, namely to obtain the color value of each pixel that the region that is blocked includes.
After obtaining the color value of central pixel point in step 202., it is possible to use the color value of the pixel not being blocked and the color value of central pixel point, it is determined that go out the color value of residual pixel point in pending region. Disclosure scheme is repaired pending region, it is possible to be presented as the color value obtaining central pixel point, and obtain the color value of residual pixel point. Further, if pending region is the whole region that is blocked, so just achieve the purpose repairing the region that is blocked; If pending region is the whole part being blocked in region, then can refer to disclosure embodiment illustrated in fig. 1, continue other pending regions are carried out repair process, can realize repairing the purpose in the region that is blocked equally.
In the technical scheme that the disclosure provides, first with the pixel not being blocked being positioned at pending edges of regions, determine the color value of the central pixel point in pending region, and then in conjunction with the pixel not being blocked and central pixel point, determine the color value of the residual pixel point in pending region, repair pending region. Such process, whether the color value of central pixel point, or the color value of residual pixel point, based on the color value of the pixel not being blocked all originally existed in picture, make the repair process more objectivity of the disclosure, additionally aid and realize seamlessly transitting of pixel color value, improve repairing effect, it is to avoid barrage occurs.
Below the method determining residual pixel point color value in disclosure scheme is explained.
Fig. 3 is the flow chart of the method for the color value of determination the first pixel according to an exemplary embodiment. First pixel belongs to the residual pixel point in pending region, namely the first pixel can be any one the residual pixel point in pending region. This determines that the method for color value of the first pixel may comprise steps of:
In step 301, from the edge pixel point in described pending region, it is determined that go out the second pixel, described second pixel is the pixel that described central pixel point intersects to the extended line of described first pixel line and the edge in described pending region.
In disclosure scheme, it is possible to use the color value of central pixel point and the color value of the second pixel, it is determined that the color value of the first pixel. Second pixel belongs to the pixel not being blocked, and as a kind of example, the second pixel can be the pixel that central pixel point intersects to the extended line of the first pixel line and the edge in pending region. Fig. 4 is the schematic diagram in the pending region according to an exemplary embodiment, and wherein, central pixel point is point0, the first pixel is point1, and the second pixel determined by extended line is point2.
In step 302, it is determined that the weighted value w of described central pixel point1Weighted value w with described second pixel2。
In step 303, it is thus achieved that the color value P of described first pixel1=P0*w1+P2*w2, P0For the color value of described central pixel point, P2Color value for described second pixel.
As a kind of example, the disclosure can utilize the mode of weighted sum, based on the color value P of central pixel point0Color value P with the second pixel2, it is thus achieved that the color value P of the first pixel1. Corresponding to this, it is possible to first determine the weighted value w of central pixel point1, the second pixel weighted value w2, then based on formula P1=P0*w1+P2*w2Obtain the color value P of the first pixel1。
In a kind of possible embodiment, it is possible to the distance according to the first pixel to central pixel point, the second pixel, it is determined that w1And w2. For example, it is possible to the distance d first obtained between central pixel point and the first pixel1, the first pixel and the second pixel spacing d2; Further according to d1And d2, it is determined that go out w1And w2If: d1>d2, then arrange and make w1<w2, and w1+w2=1; If d1<d2, then arrange and make w1>w2, and w1+w2=1; If d1=d2, then arrange and make w1=w2, and w1+w2=1. Disclosure embodiment is for w1And w2Value can not limit, as a kind of example, it is possible to according to d1And d2Ratio, it is determined that w1And w2Value.
Generally, the color value between neighbor pixel in picture can seamlessly transit mostly, does not generally have color value sudden change, and therefore, disclosure scheme can according to point from more near, and the principle that weighted value is more big arranges w1And w2.It is to say, the first pixel is the closer in which pixel, then the weighted value of this pixel is just relatively big, and still for schematic diagram shown in Fig. 4, relative point0, point1 are closer to point2, therefore may be configured as w2>w1。
Furthermore it is possible to understand ground, make w1+w2=1, help to ensure that the flatness of the first pixel color value, it is to avoid occur that color value is suddenlyd change.
To sum up, just can be simple and convenient realize seamlessly transitting of pixel color value, contribute to optimizing repairing effect to the region that is blocked.
Such as introduction made above, the edge pixel point in pending region can be all the pixel not being blocked, it is also possible to part is the pixel not being blocked. If the edge in pending region includes the pixel being blocked, then can determine the color value of the first pixel according to scheme shown in Fig. 5.

In this programme, it is determined that after going out the second pixel, it is possible to first judge that the second pixel is whether for the pixel that is blocked, and then obtain the color value of the second pixel according to judged result. If it is judged that represent that the second pixel is the pixel not being blocked, then directly can extract the color value of the second pixel from picture, use during for the color value of subsequent calculations the first pixel; If it is judged that represent that the second pixel is the pixel being blocked, then can utilize the pixel not being blocked in the edge pixel point in pending region, it is determined that go out the color value of the second pixel, use during for the color value of subsequent calculations the first pixel.
As a kind of example, it is possible to from the edge pixel in pending region point, it is determined that go out the pixel that be not blocked adjacent with the second pixel, the color value of the pixel not being blocked that recycling is determined, it is thus achieved that the color value of the second pixel. For example, it is possible to the color value of the pixel not being blocked that will determine, it is determined that it is the color value of the second pixel; Or, it is possible to the average of the color value of the pixel not being blocked that will determine, it is determined that be the color value of the second pixel; Or, it is possible to by the color value of the pixel not being blocked determined, the color value that occurrence number is maximum, it is determined that be the color value of the second pixel, etc., this can not be limited by disclosure embodiment.
Corresponding to this, disclosure scheme is repaired pending region, it is possible to be presented as the color value obtaining central pixel point, obtain the color value of residual pixel point and obtain the color value of the pixel that is blocked of pending edges of regions.
In step 504, it is determined that the weighted value w of described central pixel point1Weighted value w with described second pixel2。
In step 505, it is thus achieved that the color value P of described first pixel1=P0*w1+P2*w2, P0For the color value of described central pixel point, P2Color value for described second pixel.
In disclosure scheme, it is possible to after determining the second pixel, namely judge whether the second pixel is the pixel being blocked; Or, it is also possible to determining w1And w2Afterwards, then judge whether the second pixel is the pixel being blocked. As long as it is to say, utilizing formula P1=P0*w1+P2*w2Before calculating the color value of the first pixel, completing to judge, this can not be limited by disclosure embodiment.
