We have developed a digital image editing system that can be operated intuitively.In our system,the target image is projected onto a back projection screen,and the user retouches the image using an infrared lighting device.The quantity of infrared light hitting each part of the screen from the lighting device is captured by a CCD camera,and the image is edited according to the quantity of captured infrared light.This system makes it possible to process images directly and intuitively.Moreover,it allows two or more people to edit the image at the same time.
