摘要： A focus detection device which repeatedly calculates correlations between first and second image signals representing light intensity distributions on first and second image sensor arrays by shifting one of the image signals relative to the other to find an amount of shift affording the highest correlation includes shift range restriction means for restricting the shift range for the present correlation calculation in accordance with the amount of shift found through the last correlation calculation to afford the highest correlation. The shift range restriction is inhibited when the result of the last correlation calculation was not reliable indicating an infeasible condition of the focus detection.

摘要： A focus condition detecting device for a camera is disclosed. The device provides first and second image sensors for calculating correlations between images each having passed through an objective lens of the camera. A plurality of image detecting blocks are defined on the first image sensor in order to execute correlation calculations with respect to each block for detecting focus conditions. A focus condition which indicates the focus condition among those obtained from the correlation calculations with use of each block is employed as the most probable focus condition. In the present invention, correlation calculations unnecessary for finding the rearmost focus condition are omitted.

摘要： An automatic focusing device 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 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 object lens is driven to an infocus condition.

摘要： A solid state image sensor drive apparatus in accordance with the present invention enables a solid state image sensor to start integration of photoelectric current in response to an integration clear signal so that electric charges are accumulated to a prescribed level and transferred to a shift register. The accumulated electric charges transferred to the shift register are read out successively based on a transfer signal so that it is supplied to a microcomputer performing various operations. At this time, if a request for interruption is inputted from a load to the microcomputer, the transfer signal supplied to the shift register is stopped and the content of the shift register is not supplied to the microcomputer. When the interruption processing in the microcomputer is completed, the transfer signal is supplied again to the shift register so that transfer of data from the shift register to the microcomputer is restarted.

摘要： A camera with an AF and AE control structure including a one-shot AF mode and a continuous AF mode, in which the operability and exposure control are improved. The camera includes a unit for detecting a focusing condition of an objective lens, defined by the relationship between a position of an object to be photographed against the lens and a focus point of the lens; a unit for focusing the lens in accordance with the detected focusing condition so that the lens is moved to the in-focus position, a first light measurement unit for measuring light at a spot area corresponding to a region of the object to be detected at the detecting unit, a second light measurement means for measuring averaged light at another area broader than the first area, and a unit for controlling exposure amount. The exposure control unit determines the exposure amount on the basis of the spot metering data in a one-shot AF mode, or the averaged light measuring data which is defined as a data at a time, at least, when the lens is adjacent to the in-focus position, in a continuous AF mode.
