Image processing apparatus, storage medium and image processing method

An image processing apparatus, comprising:

• one or more processors;
• and
• a memory configured to store compute readable instructions that, when executed by the one or more processor, cause the apparatus to
• generate two intermediate image data in each of which a number of pixels in a horizontal direction is larger than that of original image data, for each of first areas formed when dividing the original image data by every five (5) first pixels in the horizontal direction, by generating each of corresponding second areas each being six (6) second pixels in the horizontal direction;
• and
• generate single output image data by mixing colors of the second pixels in corresponding positions in the two intermediate image data, wherein
• when colors of the five first pixels are “a” color, “b” color, “c” color, “d” color and “e” color from left, in the six second pixels corresponding to the second areas of the generated output image data,
• colors of the second pixels at both end are in agreement with “a” color and “e” color of the first pixels at both end of the first area of the original image data, and
• a color of each of the second pixels between the both ends is generated by mixing the colors of each set (b, a), (c, b), (c, d) and (d, e) with predetermined ratios sequentially from the left.
