ABSTRACT:
A CPU120acquires a zoom volume Z conveyed by a zoom lens position detector122, and calculates a light valve white area Sq according to that zoom volume Z. The CPU120revises the adjustment pattern image based on the calculated light valve white area Sq, rewrites the contents of the pattern image memory107, and gives instructions to project the image to an image processing unit108, and a liquid crystal light valve drive unit110, etc. On the liquid crystal light valve114is formed a pattern image for which the white part area is revised to Sq, and that revised pattern image is enlarged and projected for display on the screen. The CPU120gives instruction for sense to the imaging control unit105.By doing this, even when the zoom position of the zoom lens changes, it is possible to have the average value of the gradation value of the white part for the sensed image approximately maintain the desired gradation value.
