There is provided a projection type image display system comprising color image displaying means for displaying an image to be projected onto a screen, means for storing a correlation between an initial XYZ-tristimulus value of an image projected onto the screen at the time of initial adjustment and an initial luminance value of the image projected onto the screen at the time of initial adjustment, luminance measuring means for measuring a maximum luminance value of each of primary colors of an image projected onto the screen upon lapse of a predetermined time from the initial adjustment, means for estimating an XYZ-tristimulus value of the image on the screen upon lapse of the predetermined time based on the maximum luminance value and the correlation, and means for calculating a color correction coefficient based on the estimated XYZ-tristimulus value.
