Abstract
An image conversion apparatus extracts from among pixel rows parallel to an object pixel row, a first pixel row overlapping an aperture shape; and further extracts a second pixel row having the number of pixels successively overlapping the aperture shape equal to or greater than that of the first pixel row. The image conversion apparatus calculates a value of a second pixel in the case of converting an original image, by referring to a storage unit that stores a value of a first pixel in the case of converting the original image. For example, the image conversion apparatus defines an average of the value of the first pixel in the case of converting the original image, a value of a diffusion source pixel (IN[5][2]), and a diffusion source pixel (IN[5][3]) as the value of the second pixel in the case of converting the original image.
