Abstract:
1. An inspection system comprising an imaging device having multiple imaging elements arranged in two-dimensions along an X-axis and a Y-axis which are two virtual orthogonal axes, an imaging control section that receives a light intensity signal from all or a part of the imaging elements at a predetermined imaging timing and stores each detected light intensity value indicated by the light intensity signal as two-dimensional image data in an image storage area (D 1 ) set in a memory, and an image processing section that produces data for inspection by processing the two-dimensional image data, wherein an object (W) for inspection is imaged by the imaging device while the object is moved relative to the imaging device in an X-axis direction that is substantially parallel to the X-axis of the imaging elements, and characterized in that the imaging control section adjusts the imaging timing so as to synchronize in time a projected image unit moving time with an imaging time interval, wherein the projected image unit moving time is a time for the projected image of the object to move by “m” pixels as the object is moved in the X-axis direction relative to the imaging device, wherein “m” is an integer number greater than or equal to 1, in the X-axis direction on the imaging elements, and wherein the imaging time interval is a time interval to receive the light intensity signal from the imaging elements and to store it as a single unit of two-dimensional image data in accordance with the object (W) in the image storage area (D the image processing section comprises
