摘要:
An electronic still camera includes a camera body which has recording device for recording electrical picture signals from an image pickup device and electrical so-and signals received by a sound receiver onto a recording medium, and an adaptor detachably mounted to the camera body. The adaptor has a sound memory for temporarily memorizing the sounds for a predetermined period of time to output the same to the camera body, and a remote controller for outputting a remote control signal for remotely controlling the operation of the camera body. The camera body has a control unit for controlling the operation of the camera in accordance with the remote control signal from the remote controller.

A combination of photographic film and electronic single-lens reflex camera. An electronic imaging and recording unit is detachably mounted on the single-lens reflex camera in place of the view finder and converts the image light into an electronic signal to be recorded on a magnetic disk. The exposure control for the electronic imaging is partially performed in the main camera body.

A liquid crystal display device is provided for receiving a video signal and displaying a visual image. The display device employs an active matrix liquid crystal display member having a plurality of display elements, and a plurality of switching elements, respectively. An image signal included in the video signal is applied to the display elements in accordance with a horizontal synchronous signal. The signal corresponding to the synchronous signal included in the video signal to be applied to the switching elements is inhibited for a predetermined period of time so that the image is kept displayed by the display elements for a certain period of time without the need to supply another video signal.

A camera including an electronic focus detecting device and an optical display device for indicating whether the photographing lens of the camera is at a rear focus position, a front focus position or a correct focus position and for indicating whether the lens is being moved in the correct direction towards the position of correct focus. First and second photoelectric conversion element arrays are disposed in front of and behind a position which is optically equivalent to the position of the film surface in the camera. Signals are produced from the respective outputs of the arrays which are in proportion to the degree of focus than existing. A different signal is produced as well and the three signals are then processed to determine the indicated positions in a disclosed circuit arrangement.
摘要:
A self-scanning type photoelectric conversion element drive device, particularly, such a drive device applied to a focus detecting device of a camera, in which the effective dynamic range of the device is made very broad without a complex circuit arrangement. First and second photoelectric element arrays are scanned serially in the case that a sensed light intensity is below a predetermined value and scanned in parallel when the light intensity exceeds the predetermined value. For serial scanning, the outputs of the photoelectric elements are applied directly to an output terminal. In the case of parallel scanning, the output of one of the arrays is stored in a memory and then applied to the output terminal.
摘要:
An automatic focus indicating device especially adapted for use with a single lens reflex camera in which a contrast signal is produced by scanning the image of an object being viewed through the photographing lens of the camera. This signal is converted into an indication signal which may be either an audio or a visual signal. As the lens is moved to positions near the focus point, the indicating device is activated to a first mode. As the lens is set precisely upon the point of focus, the indicating device operates in a second mode. In this manner, the camera is well adapted for both hand-held and fixed position usage.
摘要:
A focusing system for a camera using an array of photoelectric elements to sense the level of light at points in the image plane of an objective lens. The output of the elements are scanned in sequence to form a train of pulses whose amplitudes correspond to the level of light at the respective elements as they are scanned. The pulse train is split into two pulse trains of alternate pulses. The two pulse trains are separately converted to two analog signals and applied to a differential amplifier. The difference output is clamped to a reference potential and applied to a peak detector. When the objective is in focus, the output of the peak detector is at a maximum.
摘要:
An automatic focus detecting device for a camera including a self-scanning type photoelectric conversion element array. The array is operated in two modes, a brightness detecting mode and a focus detecting mode. In the brightness detecting mode, the individual light detecting elements are connected in parallel with one another and to a brightness detection module. Once the brightness detection has been made, the scanning frequency of the array is set in accordance with the brightness value detected. The photodiode elements are then coupled in serial fashion to a focus detecting module. The position of the lens is varied until the focus detecting module indicates that the proper focalization position has been reached.
