    摘要: An automatic focusing divice for a camera is disclosed. The automatic focusing device has sensing means for sensing light intensity distributions within narrow and wide areas of a field of view of an objective lens, respectively and can be operated in either operation mode of one-shot AF mode and continuous AF mode. When the one-shot AF mode is designated, said narrow area which is narrower than said wide area is automatically selected for focus condition detection and, when the continuous AF mode is designated, said wide area is automatically selected.

    摘要: A focus condition detecting device which generated first and second light intensity distribution signals representing light intensity distributions on first and second arrays arranged to receive lights having passed through different areas of the exit pupil of an objective lens is arranged so as to divide the first light intensity distribution signal into a plurality of blocks. Each of the portions of the first light intensity distribution signal belonging to the respective blocks is shifted relative to the second light intensity distribution signal by sequentially changing an amount of shift, so that correlations therebetween are calculated for finding the amount of shift providing the highest correlation. In accordance with the amount of shift found to provide the highest correlation through the correlation calculation with use of the portion of the first light intensity distribution signal belonging to one of the blocks, the shift range for the succeeding correlation calculation with use of the portion of the first light intensity distribution signal belonging to another one of the blocks is restricted to shorten the period of time required for the succeeding correlation calculation.

    摘要: A camera with an automatic focusing device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a brightness distribution is obtained so as to detect a rough focusing condition in each zone, thereby producing a plurality of rough focusing condition data. Based on the result of the rough focusing condition data, one zone is selected. Furthermore, a precise focusing condition is detected in the selected zone based on the light contained in the selected zone, so as produce a precise focusing condition data. Based on the precise focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition.

    摘要: An image sensor system for sensing an image of an object includes a plurality of image sensor arrays. Each array comprises photoelectric converting elements arranged to receive the object image and accumulation cells coupled to each photoelectric converting element for accumulating charges produced from the photoelectric converting element. A buffer memory cells are coupled respectively to the accumulation cells for temporarily storing the accumulated charges shifted from the accumulation cells in response to the completion of the charge accumulation in each array. A shift register is provided to receive accumulated charges from the buffer memory cells in every one of the arrays after all the arrays complete the charge accumulation. The accumulated charges stored in the shift register are then sequentially outputted.

    摘要: A camera with a multi-zone focus detecting device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a focusing condition is detected based on the image formed by the objective lens so as to produce a plurality of focusing condition data. Based on the result of the focusing conditions, one zone is selected. Furthermore, a light which has passed through the objective lens is measured separately in each zone so as to produce a plurality of measured light data. Based on a focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition. When the objective lens is driven to the infocus condition, a measured light data obtained from the selected zone is used for calculating exposure data with which the exposure is controlled.
