Digital still camera, imaging method, and exposure decision method |
May 2, 2006 |
| A digital still camera has a function to perform first and second exposures in a single imaging sequence. In the first exposure, imaging conditions are determined to obtain proper exposure amount of the background with available light. Then, the second exposure is carried out with th |

Image pickup apparatus provided with a flash device |
July 22, 2003 |
| When a stop aperture formed by a shutter blade has reached a diameter corresponding to a predetermined f-number, a flash light is emitted and an exposure is performed with the flash light. Successively, the diameter of the stop aperture is gradually increased. When the stop aperture has |

Camera for taking a picture in a good focus condition |
July 22, 2003 |
| A camera uses a program shutter as a shutter device. When an exposure value becomes larger than EV9, a stop of the camera is closed down so as to increase an f-number. In a case that the camera is loaded with a photographic film having film sensitivity of ISO 1000 or more, an upper l |

Optical instrument and image photographic method |
October 9, 2001 |
| A lens-fitted photo film unit for photographing an object includes a flash charger button as mode selector, which designates a selected one of a flashless mode and a flashing mode. An exposure aperture forms a color image by object light from the object. The image, if the flashless mode |

Lens-fitted photo film unit, and method of making photo-print |
April 24, 2001 |
| A lens-fitted photo film unit can take indoor- and night-photographs at adequate tone- and color-reproductions, by satisfying the condition:wherein T, A and S represents the shutter speed, the aperture size, and the ISO film speed. The film speed is determined to be not less than ISO640, |
