摘要：
An image processing apparatus includes an extraction unit, a counting unit and an information embedding unit. The extraction unit extracts a circumscribed figure of a pixel block in an image. The counting unit counts contact portions between the circumscribed figure extracted by the extraction unit and the pixel block. The information embedding unit embeds information to be embedded by adjusting a number of the contact portions between the pixel block and the circumscribed figure extracted by the extraction unit based on the number of contact portions counted by the counting unit and the information to be embedded.
