Abstract: Provided are a method for manufacturing a low cost imaging device, the low cost imaging device manufactured by such method and a portable terminal using the imaging device. A silicon wafer 11 is cut into imaging elements 12, and a plurality of the imaging elements 12 are placed on a substrate 21. Thus only non-defective imaging elements 12 are sent to a subsequent process. By discriminating a defective imaging element 12 prior to cutting, an imaging optical unit OU is saved from being combined with the defective product whereby the imaging device can be manufactured at a low cost.

Abstract: In an apparatus for reproducing a photographed image on each frame of a developed photographic roll film, wherein each frame includes an image region on which the photographed image is provided and a memory region in which information with regard to the photographed image is stored, an information reader for reading the information stored in the memory region; a processing circuit for processing image signals photoelectrically obtained by an image reader on the bases of the information; and the processed image signals are displayed on the screen.

Abstract: A still video camera provided with a mode selector to select an operation mode, a trigger generator to generate a trigger signal and a video recorder to record a visual image of the subject and to reproduce the recorded image. When the record-play mode is selected by the mode selector, the video recorder responds to the trigger signal from the trigger generator to record a frame of the visual image of the subject. The recorded frame of the visual image of the subject is then played back. This sequence can be repeated at the direction of the operator, at predetermined time intervals, or in response to a sound amplitude greater than a predetermined level. The still video camera is also capable of recording and playing back sound to accompany the still picture.

Abstract: A driving apparatus for solid state image sensors used for an electronic still camera for taking a still picture with a solid state image sensor, and adapted to generate timing pulses for carrying out an exposure operation of the solid state image sensor and reading electric charges occurring in a light receiving portion of the solid state image sensor due to the exposure of the film. A device generates timing pulses for carrying out the exposure and reading operations of the solid state image sensor. A sweeping action controller in the timing pulse generating device makes when a predetermined voltage is applied from the outside thereto a timing pulse for sweeping the electric charges, which are accumulated in the light receiving element in the solid state image sensor, to the outside. The predetermined voltage is applied to the sweeping action controller before the starting of the exposure operation to carry out an operation of sweeping out the electric charges in the solid state image sensor.

Abstract: A still video camera includes a solid-state image pickup device including a photosensor section, a vertical transfer section for vertically transferring charge from the photosensor section, and a horizontal transfer section for outputting the charge from the vertical transfer section to the outside. The solid-state image pickup device is arranged to change an exposure time. Exposure is started at an end of transfer of the charge from the photosensor section to the vertical transfer section. Emission of an electronic flash is started on the basis of a predetermined shutter speed when a predetermined period of time has elapsed. The charge of the photosensor section in the solid-state image pickup device is transferred to the vertical transfer section when an amount of light reflected by an object to be photographed reaches a predetermined value, thereby completing the exposure.

Abstract: A weighted event counting circuit comprises a cascade connection circuit composed of a plurality of frequency dividing circuit means and a plurality of coincidence detecting circuit means inserted between the frequency dividing circuit means, and input circuit means to supply digital data representing the occurrence of plural events to the coincidence detecting circuit means. The number of occurrence times of the plural events is counted and totalized with weighting.

Abstract: A range finder wherein the quantization of analog outputs from light receptor elements for converting an optical image into an electrical signal is accomplished by comparing the outputs from at least two of the light receptor elements in each group, by dividing the outputs into the following three cases: one output is greater than the other; both are equal; and one is smaller than the other.

Abstract: The invention relates to an active type camera rangefinder for automatic focus. A beam of infrared light is emitted towards an object and the light reflected back from the object is received by a plurality of photo transistors. An automatic gain control adjusts the sensitivity of the phototransistors. An RC circuitry delays operation of the automatic gain control to eliminate low-frequency ripples caused by fluorescent lamps.

Abstract: A film feeding method wherein film is fed by a film feed motor according to pulses generated per unit moving amount of film, characterized in that the overrun amount of the film feed motor is estimated from the supply voltage obtained at starting of the film feed motor or another electrically-operated drive machine fed with power from the same power source as the film feed motor operated prior to feeding of film. The drive of the film feed motor is controlled in expectation of the estimated overrun amount, or the calculated overrun amount of the film feed motor.

Abstract: An automatic film winding mechanism and method generates a series of pulses for each unit movement amount of the film, computes the speed of the film advancing movement, compares the speed to a stored look-up table for determining the precise point at which power to the film drive motor should be shut off, in order to have the advancement of the film come to a complete stop at a predetermined film transport distance. The invention thereby allows the film to be advanced to the exact transport distance regardless of the output and voltage fluctuation of the film drive power source, or of the film variation or load variation of the motor caused by a change in ambient temperature or other conditions.
