Abstract
An image processing apparatus includes circuitry. The circuitry irreversibly compresses an input image to generate an irreversibly compressed image. The circuitry decompresses the irreversibly compressed image to generate a decompressed image. The circuitry corrects a surround of a target area in the decompressed image to generate a corrected image. The target area corresponds to a line drawing image included in the input image. The circuitry generates first to third image layers from the corrected image. The first image layer is a binary image including a line drawing alone. The second image layer includes a line drawing area. The third image layer includes a background area. The circuitry reversibly compresses the first image layer and irreversibly compress the second and third image layers. The circuitry generates an output file based on the first to third image layers compressed.
