Abstract
The invention provides a method for compensating distortion and blur based on a camera sensor. The method comprises obtaining an image comprising a pixel array, and performing distortion compensation or blur compensation on the pixel array. The method for compensating distortion and blur based on the camera sensor is capable of compensating the distortion or blur of the image and enhancing the definition of the image.
Description
Technical field
The present invention relates to camera sensor technology, particularly relate to a kind of based on the compensating distortion of camera sensor and the method for Compensation Fuzzy.
Background technology
Camera is fixed on a position, takes pictures to the object of movement, the image obtained there will be distortion, this be the image that obtains due to each scanning by exposure in the different time.When photographer holds camera shot object in the case of movement, the image obtained there will be fuzzy, and this is because within the time for exposure, this camera is moving.No matter, all can have an impact to the final effect of image if there is distortion or occurring fuzzy in image.
Summary of the invention
Provided by the invention based on the compensating distortion of camera sensor and the method for Compensation Fuzzy, to the distortion of image or fuzzyly can to compensate, strengthen the definition of image.
According to an aspect of the present invention, provide a kind of based on the compensating distortion of camera sensor and the method for Compensation Fuzzy, comprising: obtain image, described image comprises pel array; Distortion or Compensation Fuzzy are compensated to described pel array.
The embodiment of the present invention provide based on the compensating distortion of camera sensor and the method for Compensation Fuzzy, by compensating distortion or Compensation Fuzzy to the image comprising pel array, the definition of image can be strengthened.
Accompanying drawing explanation
Fig. 1 for the embodiment of the present invention provide based on the compensating distortion of camera sensor and the method flow diagram of Compensation Fuzzy.
Embodiment
What provide the embodiment of the present invention below in conjunction with accompanying drawing is described in detail based on the compensating distortion of camera sensor and the method for Compensation Fuzzy.
Fig. 1 for the embodiment of the present invention provide based on the compensating distortion of camera sensor and the method flow diagram of Compensation Fuzzy.
With reference to Fig. 1, in step S101, obtain image, described image comprises pel array.
In step S102, distortion or Compensation Fuzzy are compensated to described pel array.
Further, described image is the first image or the second image, and described acquisition image comprises at least one following process:
Taken pictures by the object of photographing device to movement and obtain the first image;
By mobile photographing device, object is taken pictures and obtains the second image.
Here, the first image obtained when adopting the method for compensating distortion normally to take pictures to the object of movement; Adopt the method for Compensation Fuzzy normally photographer hold the second image that object that photographing device takes in the case of movement obtains.
Further, described pel array comprises:
Multiple first sub-pixel, in the horizontal direction and multiple first rows of formation arranged in parallel, described first rows is the first length;
Multiple second sub-pixel, for vertically and multiple second sub-pixel column of formation arranged in parallel, described second sub-pixel column is the second length.
Particularly, the pixel of image can be, but be not limited to, be specially 1600*1200,1600 is the first length of multiple first rows, and 1200 is the second length of multiple second sub-pixel column, by adding as many again number of lines of pixels in multiple first rows, thus making the second length of multiple second sub-pixel column become 2400, overall pixel becomes 1600*2400.
Further, describedly distortion is compensated to described pel array or Compensation Fuzzy comprises:
The even number line interval first threshold time of described multiple first rows is carried out exposure successively and obtains the 3rd image;
The odd-numbered line of described multiple first rows is carried out exposure successively and is obtained the 4th image after the Second Threshold time;
Utilize the object relative displacement compensating distortion in described 3rd image and the 4th image.
Here, the first threshold time can be T
1, the Second Threshold time is T
2, the even number line of multiple first rows from the first row, at interval of T
1after time, then from next even number line, carry out exposure successively and obtain the 3rd image, the pixel of the 3rd image is 1600*1200.
Odd-numbered line is T in the even number line time for exposure
2after, then carry out exposure successively and obtain the 4th image, the pixel of the 4th image is 1600*1200.
Further, describedly distortion is compensated to described pel array or Compensation Fuzzy also comprises:
The even number line of described multiple first rows is carried out exposure successively by the first exposure parameter and obtains the 5th image;
The odd-numbered line of described multiple first rows is carried out exposure successively by the second exposure parameter and obtains the 6th image;
Described 6th image is utilized to compensate described 5th the fuzzy of image.
Here, because the time for exposure of the 6th image is short, fuzzy less, therefore can be used for the fuzzy of compensation the 5th image.
Further, described first exposure parameter is the 3rd threshold time and the first gain, describedly the even number line of described multiple first rows is carried out exposure successively by the first exposure parameter obtains the 5th image and comprises:
The even number line of described multiple first rows is carried out exposure successively by described 3rd threshold time and described first gain and obtains described 5th image.
Further, described second exposure parameter is the 4th threshold time and the second gain, describedly the odd-numbered line of described multiple first rows is carried out exposure successively by the second exposure parameter obtains the 6th image and comprises:
The odd-numbered line of described multiple first rows is carried out exposure successively by described 4th threshold time and described second gain and obtains described 6th image.
Here, can by increasing by the first gain to reduce the 3rd threshold time, thus be reduced the time for exposure of the 5th image.Meanwhile, also can by increasing by the second gain to reduce the 4th threshold time, thus be reduced the time for exposure of the 6th image.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of described claim.
