摘要： PURPOSE:To control a driving system for automatic focus detection and to eliminate malfunction by passing an output consisting of an external light component as outputs of photodetector areas and a pulse light component of a projecting element through an LPF and extracting only a DC component as the external light component. CONSTITUTION:Outputs of the areas 35A and 35B which photodetect the external light component are amplified by DC amplifiers 61a and 61b; the amplification includes down to a sufficiently low frequency and high frequency components are cut. Consequently, reflected light components of the outputs are suppressed and the amplified signals are passed through LPFs 62a and 62b to obtain complete DC signals. For the purpose, the external light components (DC component) are inputted to a differential amplifier 63 to calculate the difference, and it is discriminated whether the difference signal is larger than a constant level VC or not. When the difference is larger than V C, an object having large contrast difference which generates large difference between external light components incident on the areas 35A and 35B is judged and its output is inputted to a control circuit 51 to stop a driving motor 36 and turns on a warning lamp for display, thereby eliminating malfunction.

摘要： PURPOSE:To prevent malfunction due to an environmental change and to perform tracking operation with high precision regardless of the environmental change by providing a means which extends an update period as a stage in which a subject to be tacked is possibly at a substantial stop continues. CONSTITUTION:A movement decision circuit 114 compares values stored in a reference color memory 113 with a value extracted newly from each picture element. The period in which the storage contents of a storage means stored with tracked subject features are updated when a decision means 114 which decides on the movement of the subject according to the decision result is made longer and longer as the state in which the tracked subject is possibly at a substantial stop continues longer and longer. A reference value to replace is a value which is already calculated as the mean value of signals exetracted from respecetive picture elements in the last N-time extraction, so an extremely representative reference value is updated with little time loss without resetting the reference value by interrupting tracking operation for, for example, N/60 seconds.
