The area of image to be displayed is selected in accordance with the zoom ratio and the image of the selected area is displayed on a display screen in an enlarged form. A specially designed distortion lens may be used to take the picture of the front scene to form an image of the scene with its central area being optically enlarged.

Abstract: An illumination-component extractor (illumination component extraction section) extracts an illumination component Log from a picked-up image (original image picked up an image sensor having a photoelectric conversion characteristic which comprises a linear characteristic region and a logarithmic characteristic region. A reflectance component determiner (subtraction section) extracts a reflectance component Log (R1). A compressor (illumination component compression section) subjects at least the illumination component Log of the logarithmic characteristic region to DR compression. Image production mean (image production section) produces a new image (synthetic image) based on the DR-compress illumination component and the reflectance component.
