Title: Measuring system with improved method of reading image data of an object

Abstract: When a scanning start position set signal is input in an area image sensor,the content is transferred to a vertical scanning circuit, and the scanstart position is set. Image of a desired row is read by horizontalscanning. Then, one shift signal for vertical scanning is input, theposition of scanning is shifted by one row, and horizontal scanning isperformed. Thus image of the next row is read. By repeating thisoperation, a desired strip-shaped image is read. The shape of the objectis determined and when a portion is determined to have complicated shape,the image data is input by means of a lens having long focal length, andimage data of other portions are input by means of a lens having shortfocal length. By putting together a plurality of input image data, imagedata as a whole is generated.
