OBJECT RECOGNIZING DEVICE

摘要

PURPOSE:To judge the existence of an object in response to the change level of the nearby brightness by providing an illuminance correcting means correcting the illuminance of an image inputted by an image input means. CONSTITUTION:An image input means (CCD camera) 1 photographs an image near to an opening/closing means (shutter) 2, and the image is fed to an illuminance correcting means 5. The correcting means 5 corrects the illuminance to the optimum illuminance for an object recognizing means 6 to recognize the inputted image and outputs it to the recognizing means 6. The inputted image is stored in a present image memory means 14 as the present image. An image comparing means 15 compares the present image stored in the memory means 14 with the initial image stored in an initial image memory means 13 at the time of initial setting. When a difference is recognized between them, an object is judged to exist near to the opening/closing means 2. When no difference is recognized, it is judged that no object exists, and the result is outputted to a drive section control means 7. The control means 7 transfers a stop signal to the drive section of the opening/closing means 2 when the object exists near to the opening/closing means 2.
