    摘要: A filter for compensation of spectral sensitivity is provided in front of a light receiving element through a light shielding tube. A light source emitting such light as having wave length characteristics which fall within a sensitive wave length zone of the light receiving element yet fall outside of transmitting wave length zone of the filter is provided between the filter and the light receiving element. Light from outside irradiates the light receiving element through the filter while light from the light source is so controlled as irradiating the light receiving element but not leaking through the filter to outside, so that the light from the light source can irradiate the light receiving element without any relationship with the irradiation of outside light on the light receiving element.

    摘要: An exposure control device for a camera, having a first light receiving element for sensing light beams reflected from a film surface and a second light receiving element for sensing light beams from an object before taking a photograph. In this arrangement an auxiliary diaphragm, which is opened as a shutter is closed and is closed as the shutter is opened, is provided in front of the second light receiving element. The first and second light receiving elements are connected in parallel between input terminals of an operational amplifier for the light measuring. Accordingly, an exposure control with a high degree of accuracy is effected based on an output of the light measuring operational amplifier.

    摘要: In the disclosed camera exposure control, data recording and film winding are performed sequentially and the system is protected from battery voltage drop arising from the effective increase in consumption of electrical energy necessary to make each exposure as compared with the ordinary camera, by detecting the battery level upon occurrence of a prescribed phase of the operating cycle. In one embodiment, the battery is also checked at a subsequent step of the cycle (for example, film winding operation is permitted only when the battery level is above the predetermined level). According to an embodiment of the invention, a sequence control circuit controls the photographic operation sequentially.

    摘要: The present invention relates to a photographic camera device in which current is supplied to the winding up motor device for automatically advancing the film and cocking the shutter and to a rechargeable electronic flash light device from a single common power source battery. The camera is provided with a voltage detecting device for detecting the voltage of the power source battery, and a control device for simultaneously supplying current to the winding up motor device and the flash light device when the power source voltage detected by the voltage detecting device is higher than a certain determined voltage, and for preventing current flow to the flash light device while the current is being supplied to the winding up motor device when the detected power source voltage is lower than the determined voltage. A further device prevents the operation of the trigger button when the power source voltage is not sufficient for operating the winding up motor device in the normal way, and also prevents the winding up motor device as well as the flash light device from being substantially operated.

    摘要: An automatic exposure control apparatus for controlling the diaphragm of the camera in accordance with the preselected shutter time and the exposure value, in which a digital-to-analog converter having a counter responsive to the number of pulses supplied from a clock pulse generator through a gate produces a time variable output capable of attaining a certain level dependent upon the preselected shutter time and a light value as photoelectrically sensed, that is, an exposure value and, which is detected by a first comparator. The output of the first comparator is applied to the gate, so that the converter is set to memorize the exposure value therein. As the diaphragm presetting ring is moved from the maximum to minimum aperture position with production of a time variable output from a signal generator associated therewith, a second comparator responsive to the attainment of the time variable output of the signal generator to a level dependent upon the final output of the set converter produces an output which is applied to arresting means for the diaphragm presetting ring. This results in automatic adjustment of the position of the presetting ring. At the time the presetting ring begins to move, the diaphragm driving means is actuated causing the diaphragm means to be brought into engagement with the ring. Thus, an effective exposure aperture is established in the diaphragm means.
