PROBLEM TO BE SOLVED: To reduce the capacity of an image data storage means as a local memory without the need for using an external memory. SOLUTION: An imaging device 3 generates image data by one image pattern by converting optical information from an object into electric charge information, the image data are outputted to an image processing LSI 2, a processing data amount reduction means 30 selects only image data of a plurality of areas, a data transfer means 20 transfers the selected image data to a RAM 12 in a single chip 1, and a CPU 11 conducts white line recognition processing on the basis of the image data stored in the RAM 12. |
