摘要:
An image processing apparatus receives an image of a print medium including additional information embedded therein and separates a block including the additional information from the received image. The image processing apparatus calculates a determination amount to be used in a determination of contents involved in the additional information, and detects a block position where the additional information is embedded according to the calculated determination amount.
摘要:
