<p>It is an object to prevent mistakenly detecting a fine slant in a field image, so that noise generated on a frame image converted from the field image is reduced. An image converting device (1) is provided with a means (2) that calculates an estimate pixel value for comparing an upper line pixel value with a lower line pixel value by using the upper line pixel value corresponding to a plurality of continuous interpolation subject pixels in a line between neighboring upper and lower lines in a field image and also calculates an estimate pixel value for comparing the lower line pixel value with the upper line pixel value by using the lower line pixel value, a means (3) that searches a combination of an estimate pixel value to minimize the sum of an absolute value of a difference between the estimate pixel value for the upper line and an actual upper line pixel value and that of a difference between the estimate pixel value for the lower line and an actual lower line pixel value, and a means (4) that interpolates a pixel value in response to the minimizing combination.</p> |
