APPARATUS FOR ADJUSTMENT OF PIXEL SHIFT CAMERA AND MEASURING METHOD

摘要

PPROBLEM TO BE SOLVED: To improve accuracy in adjustment of a fine moving amount and remarkably reduce the time required therefor in a pixel shift camera. PSOLUTION: A pixel shift chart capable of differently handling the moving amounts of X and Y is employed to reduce the adjustment time of moving amount of the pixel shift camera, thereby searching for one-dimensional extreme values in two ways. Further, to reduce the time required for one trial and to avoid a problem of hysteresis, the present moving amount is measured not by repeatedly moving a CCD actually, but by repeating an arithmetic. Still further, to surely avoid the hysteresis, a series of fine moving sequences is performed in exactly the same way as that of normal photographing to pick up and store a series of moving images, and the respective moving amounts are measured.
