publication relates to a digital camera. The digital camera has
a mode of reproducing and displaying image data stored in a
memory card, and a mode of displaying a photographed
image through the digital camera. Image data and character

data such as a photographing condition, and the like.
The digital camera has a reproduction mode of displaying

video RAM 22b. The output controller outputs the extracted
icon data to the digital signal processing circuit 6 at timing of
