<P>PROBLEM TO BE SOLVED: To detect movement of an object moving at a high speed at a highly precision rate, as for a motion detection imaging device for detecting object's movement by comparing a plurality of image information items read from a solid-state image pickup device. <P>SOLUTION: The motion detection imaging device comprises optical lenses L1 and L2 for condensing light from an object, a solid-state image pickup device 6 for photographing image information A and image information B formed respectively by the optical lenses L1 and L2, a reading means for reading the image information A and the image information B, and a microprocessor for comparing the image information A and the image information B to detect object's movement. The reading means is a rolling shutter apparatus 7 for reading a pixel of the solid-state image pickup device 6 along the direction of Y for each of read-out lines x1, x2, ... along the direction of X. The optical lens L1 and L2 are arranged so that the image information B may be shifted to the image information A along the direction of Y by only a predetermined amount d. The predetermined amount d is set at one third of a length D of the image information A in the direction of Y so that the image information A and the image information B may produce an overlap section in the direction of Y. <P>COPYRIGHT: (C)2009,JPO&INPIT |
