  • Patent number: 7570883
    Abstract: An image pickup apparatus includes an automatic exposure controller automatically controls ISO sensitivity in response to the output signal of an exposure metering circuit, and controls the exposure so that exposure setting is determined based on the brightness values of both the central photometry area and the remaining photometry area of an imaging frame. The automatic exposure controller controls the exposure setting so that when the ISO sensitivity is set to its higher value, the weighting factor of the central photometry area is higher than that of the remaining photometry area. The automatic exposure controller further determines whether or not a light source is behind an object, and, if it is the case, reduces the adjusted exposure setting so as to increase the amount of light incident on the image pickup apparatus.

    Abstract: A radiation-sensitive coating material, in addition to a base polymer, has a solvent and a radiation-active substance which forms an acid on irradiation by light (including energetic electrons or ions), a fluorescent substance which alters its fluorescence property subject to a change in the acid content of its surroundings. In a process for exposing a substrate coated with the coating material at least one sensor in the exposure chamber of the exposure apparatus measures the intensity of the change in fluorescence spectrum as a function of time during the exposure operation. From the course of intensity at the time of an individual line of the fluorescence spectrum or the intensity integrated over a wavelength interval it is possible to determine the endpoint of the exposure operation by way of electronic algorithms. Deviations from experimentally determined ideal curves of the intensity course provide information on erroneous functions in the course of coating material application and exposure.

    Abstract: A camera has a bar code reader for reading a bar code from a roll film loaded therein. Bar code data read from the bar code is checked out whether it has a proper format or not. If the bar code data read from the bar code of the loaded roll film is proper, the bar code data is written in a nonvolatile memory, and the camera is set up in accordance with the bar code data. The bar code data of the nonvolatile memory is renewed each time proper bar code data is obtained. If the bar code data read from the bar code of the loaded roll film is improper, a display device displays film data represented by bar code data having been stored in the nonvolatile memory, along with an error indicia. If the displayed film data is invalid for the loaded roll film, the photographer enters film data of the loaded roll film through manual operation switches. Then, the camera is set up with the manually entered film data. If no film data is manually entered, the camera is set up in accordance with the displayed film data.

    Abstract: An apparatus having a judging device judges whether a film frame is exposed or not by detecting that a magnetically recorded signal exists or not on a magnetic recording section arranged correspondingly on each frame of a film. The device judges, when it is judged that one frame is an unexposed frame by detecting no recorded signal on the magnetic recording section, whether a following frame is exposed or not. And, if it is judged that the following frame is also an unexposed frame, it is judged that the previous frame is not exposed. Thus, an accurate judgment of an unexposed frame and film feeding of a head frame of unexposed frames to a photographing position can be achieved.

  • Patent number: 5655162
    Abstract: A film feeding device of a camera includes a film feeding mechanism which has an initial winding mode to feed film mounted in the camera and wind a first frame to a shooting position, a first frame winding mode to wind the film by one frame subsequent to shooting, a manual rewinding mode to rewind the film into a film cartridge when a rewinding operation member is operated, and an automatic rewinding mode to rewind the film into the cartridge when the film is rewound through the final edge during rewinding of the film by one frame. A frame number counting mechanism counts a number of shootable frames remaining each time one frame is wound, and counts a number of frames remaining to be rewound each time one frame is rewound.

  • Patent number: 5603067
    Abstract: A camera is of a type using the 120 size of roll film or the 220 size of roll film, which is so arranged that the height of a pressure plate on a back lid is changed over depending upon a type of a used film. A reflection-type photosensor is provided in the camera body, whereby a state of a lock mechanism of the back lid is detected. A second reflective plate is mounted on the pressure plate, and the second reflective plate reflects light from the photosensor when the back lid is in a lock state. A reflecting position where the light from the photosensor impinges is changed between reflective portions depending upon the height of the pressure plate. Since reflectivities of these reflective portions are different from each other, the height of the pressure plate, that is, the type of the used film can be determined by analyzing an output from the photosensor receiving the reflected light from the second reflective plate.
