PURPOSE:To attain simple and high speed detection of a part or all of a shape of an object to be detected by digitizing an image signal of the object and processing digitally the picture data. CONSTITUTION:All data addresses of an optical random access memory 1a are outputted sequentially from an image sensor scanning circuit 2 and stored in a frame memory 3. When the data of one picture is stored in a memory A of the frame memory 3, the memory A becomes a data read only memory. Then a memory B being a data read only becomes a data write only memory. Thus, the device can correspond separately to the picture input from an image sensor head 1 and the picture read from a video signal generating means 4 at the same time. The picture data of the inputted one picture is displayed on a monitor television receiver 5 as a binary-coded image. The operator inputs the data requiring scanning from an input keyboard 6 to a picture processing circuit 7 while observing the picture displayed on the monitor television receiver 5. |
