Abstract: An appropriate adjustment can be made on the basis of a gradation amplitude obtained from a photographing image even when the zoom position of a zoom lens is changed. According to exemplary embodiments a CPU obtains a zoom amount transmitted from a zoom lens position detecting section, and derives the width of a stripe element in a pattern image to be formed on a liquid crystal light valve on the basis of the obtained zoom amount by referring to a stripe element width table stored to a stripe element width table storing section.

Abstract: A CPU 120 analyses an imaged image, derives an average gradient value L of a white portion in an imaged image, and makes a comparison to a desired gradient value Lt. If the result of the comparison is that the average gradient value L of the white portion is lower than the desired gradient value Lt, than the CPU 120 alters an adjustment pattern image so a light valve white area Sq decreases in order to increase the average gradient value L of the white portion. If it is the case where the average gradient value of the white portion is higher than the desired gradient value Lt, the CPU 120 alters the adjustment pattern image such that the light valve white area Sq increases in order to lower the average gradient value L of the white portion. When the average gradient value L of the white portion becomes equivalent to the desired tone value Lt, the CPU 120 instructs the image controller 105 to image.

Abstract: A CPU 120 moves a zoom lens 116 to the wide-angle side (step 102). When the end on the wide-angle side is reached, the CPU 120 stops the driving of the zoom lens 116 and starts image projection and imaging (S106). The CPU 120 gradually moves the zoom lens 116 to the telescopic side (S108), and pays attention to the positional relationship between a projection area 204i and a frame 202i of a dedicated screen with frame shown on a imaged image 150 to determine whether a side of the frame 202i of the dedicated screen with frame and a side of the projection area 204i overlap or if a corner of the projection area 204i and a side of the frame 202i of the dedicated screen with frame overlap (S110 and S112). If there is an overlap, the CPU 120 stops driving the zoom lens 116 (S114). It is thereby possible to automatically adjust the size of a projection area projected on a dedicated screen with frame or the like to a desired size without, for example, making a keystone correction.
