Described is an electronic device and an electronic device control method. If voltage generated by the fuel cell, acquired from the voltage detection part, is greater than a specified voltage reference value (VRV), a display part displays the fuel cell as normal. However, if the generated voltage is smaller than the VRV, the residual fuel amount (RFA) detection part detects the RFA. If the RFA is smaller than a specified fuel reference value (FRV), the display part displays that the fuel is insufficient. However, if the RFA is greater than the FRV, the oxidizing agent concentration (OAC) detection part detects the OAC of the fuel cell. If the OAC is smaller than a specified OAC reference value, the display part displays that the oxidizing agent is insufficient. However, if the OAC is greater than the OAC reference value, the display part displays that the fuel cell is abnormal.

A camera capable of conducting a wireless communication includes a wireless communication circuit and a wireless communication antenna. The wireless communication antenna, which is disposed at a non-metal movable member that can advance and retreat relative to a camera body, moves relative to the camera body.

A visual line detection camera includes a detector to detect the visual line position of a photographer, an area determination device to determine the fixation area using an equation containing compensation terms unique to the photographer in conjunction with the results of detection accomplished by the detector, a display to display the area corresponding to the fixation area obtained by the area determination device, a fixation area selector enabling the fixation area to be altered by external operation, and a compensating factor adjustment device to alter the compensation terms in the equation when the area determined by the equation and the fixation area after alteration are different as a result of alteration by the fixation area selector. This structure enables the camera to adapt to different photographers in accordance with different photographer physical attributes, providing a visual line detection camera with a high degree of reliability.

Visual line detection camera and method

A camera includes a photo-taking lens, an automatic focus adjusting device for effecting the automatic focus adjustment of the photo-taking lens, an eye-gaze detecting device for detecting the photographer's eye-gaze position in a finder field corresponding to a photographing picture plane, and producing an eye-gaze detection signal corresponding to the eye-gaze position, a focus adjustment signal producing device for outputting a plurality of focus adjustment signals corresponding to a plurality of detection areas in the photographing picture plane, and a control signal producing device for producing a control signal for controlling the automatic focus adjusting means, on the basis of the eye-gaze detection signal and the focus adjustment signals. The control signal producing device produces the control signal on the basis of the plurality of focus adjustment signals corresponding to the plurality of detection areas when the eye-gaze position indicated by the eye-gaze detection signal is at a position between the plurality of detection areas.

A user-friendly camera with a visual line detection system simplifies the operation by making manual selection possible for establishing an auto focus region directly without going through time consuming procedures, even when the camera is selecting an auto focus region based on visual line information. An auto selection mode, a visual line selection mode, and a manual selection mode are available for establishing an auto focus region with mode selection being made by an auto focus region switching system. When selection of the auto focus region is being executed in the visual line selection mode, signals from the auto focus region manual selection system may be entered so that the manual selection input takes priority and the intention of the photographer becomes the priority. The change of mode is temporarily executed easily during the visual line selection mode operation.

A multi-function camera having a display unit in which the different operational modes are displayed in different colors. The operational modes are controlled by manipulation members on the exterior surface of the camera. The manipulation members are color coordinated with the respective operational modes. As a result, a photographer can quickly consult the display unit to find out the operational mode that the multi-function camera is operating in. Furthermore, the color coordination also makes it easier for a photographer to set the multi-function camera in the proper operational mode.

A camera with a visual line position detection device capable of highly accurate determinations even when diopter adjustment is accomplished after initial completion of correction of the visual line position determining system. The camera includes a screen to form a subject image, a pentagonal prism provided inside the finder, a visual line position detection device equipped with a light emitting unit and a light receiving unit to detect the visual line position, and a diopter adjustment lens placed on the photographer's side of the pentagonal prism. The diopter adjustment lens is displaced after the correction of the visual line position detection device, and a correction coefficient needed to compute the visual line position on the screen obtained during the correction of the visual line position detection device is changed according to the displacement amount of the diopter adjustment lens.
