Abstract: An electronic camera operates with a small, portable computer having a card interface of the type used for communicating with a removable memory card. The camera includes an image sensor for converting an image into an electrical signal, an A/D converter for converting the electrical signal into a digital signal, and a signal processor for interfacing the digital signal to the card interface, ordinarily a slot receptacle, on the computer. By defining the interface to include a mechanical extender that physically interconnects the camera to the card slot on the computer, the camera and computer are linked in a high speed interface as a convenient, hand-held unit.

Abstract: A photoelectric converting device is provided with a control electrode area consisting of a semiconductor of a first conductive type, first and second main electrode areas consisting of a semiconductor of a second conductive type different from the first conductive type, and a drive line capacitively coupled to the control electrode area for controlling the potential thereof, and adapted to read a signal from the first main electrode area, by the potential control of the control electrode area, based on a charge generated by an incident light energy and accumulated in the control electrode area. The potentials of the first main electrode areas and of the drive line are elevated during the light signal accumulating operation to elevate the potential of the control electrode area, thereby rendering the potential difference between the control electrode area and the second main electrode area smaller than at the end of charge resetting of the control electrode area.
