Abstract: <P>PROBLEM TO BE SOLVED: To provide an image processing apparatus, an electronic camera and an image protection method which are capable of securely protecting images not desired to be seen by other people, and making it difficult for another person to release the protection.  <P>SOLUTION: An image protection mode is provided on a camera, and protection processing is applied to an image photographed in the image protection mode.

To release the image protection, a key release scene is photographed and the photographing scene of the key release scene is determined using the light source kind determination of the white balance control. If the photographing scene of the key scene matches the photographing scene of the key release scene, the image protection is released. Since authentication keys of the protection and the protection release are such a vague thing as the photographing scenes, it is difficult for another person to decode the authentication key. Also, since the white balance control of a camera is used for authentication of the image protection and the image protection release, the calculation processing burden of the camera can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
