Wherein, P2_high (h, w) indicates the position in the corresponding second processing image of enlarged drawing of the original image first direction In the pixel value for the pixel that h rows, w are arranged, P1_out (h, w) is indicated in the enlarged drawing of the original image first direction The pixel value of the pixel (h, w) arranged positioned at h rows, w, P1_out (h, w-1) indicate putting for the original image first direction The pixel value of the leftmost pixel point of the pixel, P1_out (h, w+1) indicate putting for the original image first direction in big image The pixel value of the right pixels point of the pixel in big image, h and w are the integer more than or equal to 0；

Each pixel in the enlarged drawing of original image first direction described in the controller searching loop, obtains corresponding The corresponding pixel value of each pixel in second processing image is corresponded to the enlarged drawing of the determination original image first direction Second processing image.

5. mobile terminal according to claim 1 or 2, which is characterized in that the controller in a second direction, to described Original image enlarged drawing in a first direction and corresponding second processing image obtain the original image most into row interpolation Whole enlarged drawing refers to：

When the first direction is the line direction of pixel, the controller determine be located at the 2nd in final enlarged drawing × H-1 rows, w row pixel pixel value be equal to third pixel value and the 4th pixel value and value, and determination is finally being amplified Pixel value in image positioned at 2 × h rows, the w pixel arranged is equal to the difference of third pixel value and the 4th pixel value, In, the third pixel value is the picture for being located at h rows, the pixel that w is arranged in the enlarged drawing of original image first direction Element value, the 4th pixel value are to be located at h in the corresponding second processing image of enlarged drawing of original image first direction The pixel value for the pixel that row, w are arranged, wherein h, w are the integer more than or equal to 0；

Alternatively,

When the first direction is the column direction of pixel, the controller determine be located in final enlarged drawing h rows, The pixel value of the pixel of 2 × w-1 row is equal to third pixel value and the 4th pixel value and value, and determine in final enlarged drawing It is located at h rows as in, the pixel value for the pixel that 2 × w is arranged is equal to the difference of third pixel value and the 4th pixel value, wherein The third pixel value is the pixel for being located at h rows, the pixel that w is arranged in the enlarged drawing of original image first direction Value, the 4th pixel value be in the corresponding second processing image of enlarged drawing of original image first direction be located at h rows, The pixel value of the pixel of w row, wherein h, w are the integer more than or equal to 0；

6. a kind of image processing method, which is characterized in that including：

Input unit inputs pending original image；

Controller determines the corresponding first processing image of the original image；In a first direction, to the original image and right The the first processing image answered obtains the enlarged drawing of the original image in a first direction into row interpolation；

Controller determines the corresponding second processing image of the enlarged drawing of the original image in a first direction；In second direction On, to original image enlarged drawing in a first direction and corresponding second processing image into row interpolation, obtain the original The final enlarged drawing of beginning image；

Wherein, the first direction is perpendicular to the second direction；

The controller determines the corresponding first processing image of the original image, including：

P1_high (h, w)=(2 × P1 (h, w)-P1 (h, w-1)-P1 (h, w+1))/4,

7. according to the method described in claim 6, it is characterized in that, the first direction is the line direction of pixel, described the Two directions are the column direction of pixel；Alternatively, the first direction is the column direction of pixel, the second direction is pixel Line direction.

8. the method described according to claim 6 or 7, which is characterized in that the controller in a first direction, to described original Image and corresponding first processing image obtain the enlarged drawing of the original image in a first direction into row interpolation, including：

Alternatively,
