Patent ID: 8169543

Claim:
An image conversion device comprising: a pixel value estimate unit configured to obtain a plurality of first estimate pixel values in a third line, which is between a first line and a second line, from a plurality of pixel values in the first line, and to obtain a plurality of second estimate pixel values in the third line from a plurality of pixel values in the second line; a combination search unit configured to search for a combination of the first and second estimate pixel values minimizing a first calculation value calculated on a basis of a first difference value between the second estimate pixel value and a predetermined pixel value in the first line and a second difference value between the first estimate pixel value and a predetermined pixel value in the second line; and a pixel interpolation unit configured to calculate a pixel value of the pixel to be interpolated from the pixel values of the first and second lines corresponding to the combination of the first and second estimate values minimizing the first calculation value.
