Abstract:
1. An image display device having a display for displaying images comprising: an image sensor for converting an image of a subject into an image signal; a driver for chronologically retrieving said image signal by driving said image sensor at a predetermined frame rate; a plurality of signal processing sections wherein each signal processing section concurrently simulates a different photographic effect of said image signal based on different shooting conditions including shutter speeds or different shooting modes by processing said image signal; a display controller for displaying images of a plurality of image frames produced in said plurality of signal processing sections side by side on said display; a designator for designating said shooting conditions or said shooting modes; a selector for selecting one of said plurality of image frames displayed on said display, wherein when releasing a shutter, an image is recorded under the shooting condition or said shooting mode corresponding to said selected image, wherein said plurality of signal processing sections comprises at least a first signal processing section and a second signal processing section, said first signal processing section simulating a first image frame based on a first shooting condition designated by said designator and said second signal processing section simulating a second image frame based on a second shooting condition designated by said designator, wherein said first shooting condition comprises a first shutter speed and said second shooting condition comprises a second shutter speed slower than said first shutter speed, said image signal obtained with said first shutter speed being input to said first signal processing section and said second signal processing section to produce said first image frame and said second image frame, wherein when a frame rate corresponding to said second shutter speed is slower than a frame rate of said display, said first signal processing section or said second signal processing section performs frame adding to said image signal from said image sensor such that said frame rate of said image sensor corresponds to said frame rate of said display.
