When a continuous-zoom-photographing mode is selected, a through image of a subject and first and second continuous-zoom-photographing frames are produced on an image-display section. When a user operates a cross key, recorded information about a trimming position of each of the first and second continuous-zoom-photographing frames is updated according to the cross-key operation, and the first and second continuous-zoom-photographing frames are produced at the updated trimming position recorded after the update. When a shutter button is operated, still-image photographing is started and obtained image data is stored in a buffer memory. On the basis of the obtained image data, image data is generated for each of the first and second continuous-zoom-photographing frames through trimming processing and stored in the buffer memory. The obtained image data and the generated image data are stored in a flash memory.
