PROBLEM TO BE SOLVED: To directly compose image without performing any complicated arithmetic processing by providing an image composing means for an image reading means to read a composite image overlapping a display image and a recorded image in the state of overlapping a read original on the displayed image. SOLUTION: Light emitted from a back light 21 of an image display member 20 is transmitted through a panel 22 on which the display image is displayed and a read original F recording the recorded image and detected through an image forming lens 31 by a CCD 32. Namely, the optical image of the composite image overlapping the display image and the recorded image is formed on the photodetecting plane of the CCD 32, and this image is converted to an electric composite image signal by the CCD 32. The composite image signal is amplified by an amplifier 41 and converted from an analog signal to a digital signal by an A/D converter 42 later. The digital composite image signal is subjected to the processing such as shading correction or interpolating processing in a signal processing circuit 45. |
