  • Patent number: 8610745
    Abstract: In order to provide a technique allowing easy confirmation of image contents even if the number of images increases, a display console includes a display device having an image displaying function and a display control unit controlling the display by dividing a display screen of the display device into an image preview area and another area. The display control unit switches, in accordance with a user instruction, between a fit-to-screen screen image in which area ratio between the preview area and another area has a first value, and a finish preview screen image, an image edition mode screen image, or a document display mode screen image, in which the size of another area is made smaller and the size of preview area is made larger than in the fit-to-screen screen image.
