PURPOSE:To make the constitution of a range detecting device provided with a blur detecting function simple and small in size by storing three groups of photoelectric converting outputs of two images by different optical paths, and detecting a range and a blur based on the respective storage contents of other image, which have been stored simultaneously. CONSTITUTION:Three groups of photoelectric outputs of two images passing through different optical paths by line sensors 1a, 1b are stored successively in storing circuits 4-6 through an A/D converter 2, a distributor 1, etc. The contents of these circuits 4-6 are selected by selecting circuits 7, 8 which are brought to sequence control, the storage contents of other image from one of the circuits 4-6, or the storage contents of the same image before or after the circuits 4-6 are processed by a correlation processing circuit 9, and a range or a blur quantity is detected. In this way, the constitution of a range detecting device provided with a blur detecting function becomes simple and small in size by this electrical blur detection which requires no mechanical mechanism. |
