ABSTRACT:
A white balance adjusting device mounted in an electro-developing type camera in which an electro-developing recording medium, which electronically develops an image formed thereon, is used. A mask member, in which first and second color filters are provided, is disposed in front of an electro-developing recording medium. The electro-developing recording medium has a recording area, in which a color image is recorded, and a data area, in which optical information used for a white balance adjustment is recorded. The first color filter faces the recording area, and the second color filter faces the data area. In the camera body, a diffuser and a light leading member are provided at a position corresponding to the second color filter.
