PROBLEM TO BE SOLVED: To obtain a visual field experiencing device of spectacles capable of executing image processing at a high speed by adopting the constitution to execute the processing to determine the averaging range at the time of averaging processing of pixel data according to a spreading quantity of luminous fluxes with all the pixels, processing to obtain visual field images by subjecting intermediate images to the averaging processing, etc. ;SOLUTION: The original image data (color and luminance data of the object surface viewed through spectacles) of the selected images is read into a memory section 14 of a personal computer 10. Next, the direction (distortion) of the object when viewed through lenses is determined and the spread of the luminous fluxes appearing blur is determined for a small number of the pixels. The original images are then processed from the determined direction of the object and the intermediate images added with the distortion when the object is viewed through the spectacle lenses are formed. Further, the averaging range where the pixel data is subjected to the averaging processing according to the spreading quantity of the luminous fluxes is calculated. As a result, the formation of the visual field images added with the blur changing the sharpness depending upon places in addition to the distortion is made possible and the user is able to experience the visual field images in the nearly actual state.;COPYRIGHT: (C)2000,JPO
