Document Type and Number:

WIPO Patent Application WO/2014/033867

Kind Code:

A1

Abstract:

In order to decrease the processing time of a blurring effect process, an image conversion apparatus (100) extracts, from rows of pixels parallel with an object row of pixels, a row of pixels of y = 7 as a first row of pixels that overlaps an aperture shape (101). The image conversion apparatus (100) further extracts a row of pixels of y = 4 as a second row of pixels of which the number of pixels successively overlapping the aperture shape (101) is not less than that of the first row of pixels. Thereafter, the image conversion apparatus (100) refers to a storage unit storing the value of a first pixel in a case where an original image (IN) is converted, and calculates the value of a second pixel in a case where the original image (IN) is converted. Specifically, the image conversion apparatus (100) determines an average of the value of the first pixel in the case where the original image (IN) is converted, the value of a diffusion source pixel (IN[5][2]), and the diffusion source pixel (IN[5][3]) as the value of the second pixel in the case where the original image (IN) is converted.
