Claim One:
1. A still image display device comprising: a recording medium for recording an in-focus image and an out-of-focus image obtained by imaging an identical object; a reader for reading out said in-focus image and said out-of-focus image from said recording medium; a blur evaluation value calculator for calculating a blur evaluation value based on a high frequency component contained in said in-focus image and said out-of-focus image; a blur evaluator for evaluating the degree of blurriness of said out-of-focus image relative to said in-focus image by comparing said blur evaluation value with a predetermined reference value; a mixture ratio determiner for choosing a first mixture ratio set in a case where said blur evaluation value is evaluated to be equal to or more than said reference value, and choosing a second mixture ratio set in a case where said blue valuation value is evaluated to be less than said reference value, provided that said first mixture ratio set refers to one set having a gradually varying mixture ratio for mixing said in-focus image and said out-of-focus image, and said second mixture ratio set refers to one set having a higher mixture ratio of said in-focus image and a lower mixture ratio of said out-of-focus image than said first mixture ratio set; a mixed image generator for generating a plurality of mixed images from said in-focus image and said out-of-focus image read out of said recording medium in accordance with a chosen one of said first and second mixture ratio sets; a display unit for displaying said mixed images; and a display controller for sequentially displaying said plurality of mixed images on said display unit.
