PURPOSE:To enable changes in the opening/closing speed of an opening/closing part at an arbitrary position by detecting the opening/closing part from the inputted image, detecting the position and the speed of the opening/closing part, and controlling the opening/closing operation of the opening/closing part on the basis of the detected values. CONSTITUTION:The vicinity of an opening/closing part 1 is photographed by an image input means 3, and the background image is written in a background image memory part 8 of a moving body detective means 4. And the present image is written in a present image memory part 7. Differential calculation of the memory parts 7, 8 is executed by a differential means 9, the image obtained by the differential means 9 is binarized in accordance with the specified value by a binarizing means 10, and the moving opening/closing part 1 is detected from the images photographed by the image input means 3. Successively, the position and speed detective means 5 detects the position and the speed of the opening/closing part 1 from the output image of the moving body detective means 4. Control of changing of the moving speed, stopping or the like of the opening/closing part 1 is realized through an opening/closing means 2 by a control means 6 in accordance with the positional and speed information from the position and speed detective means 5. |
