摘要： A focus detection system includes a line sensor array having areas including pixels, wherein the line sensor array photoelectrically converts object light received by each pixel into electric charges, and outputs accumulated electric charges as an image signal; monitor sensor arrays, adjacent to the areas of the line sensor array, for monitoring amounts of light received thereby to output monitor signals, respectively; a controller which terminates an integral operation of the line sensor array immediately after the monitor signals reach an integration termination value; and a saturation detecting device for detecting whether the image signal reaches a predetermined level of saturation. If the saturation detecting device detects that the image signal reaches the predetermined level of saturation, the controller changes the integration termination value so that the monitor signals reach the integration termination value quicker, and makes the line sensor array perform the integral operation again.

摘要： A substrate in which a minute ruggedness structure including columnar projections is formed in a track shape is prepared. The pitch of the columnar projections of the ruggedness structure is set such that a plurality of the columnar projections is within a beam spot. A flat portion is disposed between adjacent tracks. A reflecting layer is formed on the substrate. The flat portion becomes a mirror surface because of the formation of the reflecting layer. The reflectance of the ruggedness structure becomes significantly lower than the reflectance of the flat portion. When the ruggedness structure is irradiated with high-power laser light, a portion of the ruggedness structure is raised to a reflecting layer side and flattened. At this time, reflectance of the raised portion becomes higher than reflectance of a non-raised portion. When a track including the ruggedness structure is irradiated with high-power pulse laser light, signal recording based on a change in reflectance is possible.

摘要： A focus detection device includes line sensors which photoelectrically convert and integrate light from an object and output an image signal; monitor sensors, provided adjacent to the line sensors, which monitor an integrated value of the adjacent line sensors; a control device which amplifies an output of each monitor sensor and outputs a monitor signal, and terminates integration of the line sensor corresponding to the monitor sensor when the monitor signal reaches a predetermined termination value; and a gain adjustment device which adjusts a gain level of the control device in accordance with each integration time during integration of the line sensor. The gain adjustment device adjusts the gain level of the control device so that an appropriate integrated value of the line sensor becomes an approximately predetermined value when the monitor signal reaches the predetermined termination value regardless of the integration time.

摘要： An automatic focusing apparatus in which the quantity of auxiliary light can be precisely controlled regardless of conditions of an object to be taken is disclosed. The apparatus includes a passive AF sensor unit, a flash device and a main CPU which controls the flash device as an auxiliary light source for the focus detection, so that the flash device intermittently emits flashes of light. The main CPU increases emission time and emission time interval stepwise from the minimum value when the flash device intermittently emits flashes of light as the auxiliary light source upon detection of the focused state.

摘要： The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor. The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.
