Embodiment Construction

[0058] A first embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0059] image 3 is a block diagram showing the configuration of an image processing apparatus according to the first embodiment of the present invention.

[0060] exist image 3 Among them, the security encoding unit 1000 is used to encode the security information that allows or prohibits the generation of all or part of the moving image. A video encoding unit 1001 encodes moving image data.

[0061] In this embodiment, a description will be given of encoding of moving picture data using the MPEG-1 encoding system. The MPEG-1 encoding system itself will not be described here, because the work related to MPEG-1 has been given in full detail in ISO / IEC11172-2. In addition, for simplicity of description, it is assumed here that moving image data of each frame is encoded, and that a one-frame mode for intra-frame encoding and a P-frame mode for usin...

Abstract

Disclosed are an image processing apparatus and a method therefor, which are characterized by the input of image data, the generation of security data to protect said image data, the control of an encoding mode in accordance with said security data, and the encoding of said image data using said encoding mode that is controlled. Said image processing is performed to protect a copyright for an image.

Description

technical field [0001] The present invention relates to image processing for copyright protection of images and the like. Background technique [0002] Recently, the standardization of moving image coding techniques has rapidly advanced. Coding standards such as MPEG-1, MPEG-2, H.261, and H.263 (these coding systems are recognized as international standards of ISO (International Organization for Standardization) and ITU (International Telecommunication Union)) are currently established . In addition, work has progressed in MPEG-4, a new international standard expected to be a next-generation general multimedia coding standard that can be used in many fields such as computers, broadcasting, and communications. The use of coding technology can digitize the image, so that the storage and transmission of moving image data can be significantly improved. [0003] For example, with MPEG-4, a moving picture scene at a specific instant is the sum of the objects of these scene part...
