摘要： The auto focus system obtains focus information on a lens-interchangeable camera body of a TV camera and sends the focus information to a lens apparatus mounted on the camera body. The lens apparatus controls an auto focus based on the focus information. It is thereby possible to control the focus on adequate conditions according to optical specifications of the lens apparatus and so on.

摘要： The lens apparatus permits rapid focusing by the operator demanding an autofocus start-up direction to carry out AF in the direction in an AF mode. When a start of the AF mode is instructed, an AF standby state of waiting for the operator to demand the AF start-up direction by operating a focus operation member, thereby permitting the operator to properly demand the AF start-up direction, and permitting the demand to be appropriately detected. When automatically switching from the state where the operator operates the focus operation member to the AF, condition of the switching is that a focus evaluation value exceeds a predetermined threshold based on the operation of the focus operation member, or that an operation amount of the focus operation member is changed more then a predetermined amount, thereby permitting further rapid focusing and improvement of operability. Gradually switching a clutch, which switches the focus lens driving from manual to electrical operation, from a manual to electrical state in switching to the AF can eliminates uncomfortable operation feeling of the focus operation member. Further, for the processing after completion of focusing by the AF, a mode of returning to the AF standby state of waiting for the operator to demand the AF start-up direction, mode of returning to a manual mode, or mode of continuing the AF can be selected, which permits improvement of convenience of the AF mode.

摘要： Auto focus control is exerted based on a focus evaluation value indicating a degree of sharpness of an image obtained from a plurality of image pickup devices placed at positions of different light path lengths. There is provided a device which makes a correction on sensitivity of the focus evaluation value obtained from each image pickup devices. It is thereby possible to make an adequate correction on a sensitivity of the focus evaluation value so as to exert the auto focus control with high accuracy. It is also possible to automatically make a correction on the sensitivity of the focus evaluation value and eliminate troublesome labor. All or a part of signal processing for the auto focus control is performed by a single processing part by time-sharing. Thereby, a circuit scale can be miniaturized and power consumption can be reduced.

摘要： A drive unit is installed in, for example, a manually operated cinema photographing lens and connected to a system controller so that the system controller can electrically control the focus, zoom, and iris of the photographing lens. When a select switch of the system controller or a PC is used to specify the type of the photographing lens, the system controller executes a process adapted to the type of the photographing lens.

摘要： When it is detected that a tracking target disappears in an image range in the course of tracking the tracking target, which is a registration pattern selected as a target to be tracked from among registration patterns, an autofocus is disabled. Thereafter, the autofocus is kept being disabled even if it is detected that the tracking target having the selected registration pattern appears in the image range. Alternatively, when the tracking target disappears in the image range in the course of tracking the tracking target, the autofocus is disabled, and thereafter when the tracking target having the registration pattern appears in the image range, it is started to track the tracking target having the registration pattern.
