Patent ID: 8228430

Claim:
An image processing device, comprising: a memory, in which an image field is temporarily stored; a data bus and a line buffer, coupled to the memory to convey and buffer data of ten pixels of the image field, wherein the ten pixels are located on a first column, a second column, a third column, a fourth column and a fifth column of a first row and a second row of the image field; and a deinterlacing module, coupled to the line buffer, estimating data of an interpolated pixel according to the data of the ten pixels, wherein the interpolated pixel is inserted between the first and second rows of the image field on the third column to form a deinterlaced image frame, wherein the deinterlacing module further calculates: a first first data difference between the pixels of the first row, first column and the second row, third column of the image field, a first second data difference between the pixels of the first row, second column and the second row, fourth column of the image field, a first third data difference between the pixels of the first row, third column and the second row, fifth column of the image field, a second first data difference between the pixels of the first row, second column and the second row, second column of the image field, a second second data difference between the pixels of the first row, third column and the second row, third column of the image field, a second third data difference between the pixels of the first row, fourth column and the second row, fourth column of the image field, a third first data difference between the pixels of the first row, third column and the second row, first column of the image field, a third second data difference between the pixels of the first row, fourth column and the second row, second column of the image field, and a third third data difference between the pixels of the first row, fifth column and the second row, third column of the image field.
