Patent number: 7088395Abstract: The invention concerns an image-capturing apparatus and an imager. The image-capturing apparatus includes the imager in which a plurality of circuit cells are two-dimensionally aligned, and an electronic charge, photo-electronically converted from a received light and stored in each circuit cell, can be discharged from an arbitral circuit cell. The imager includes first group circuit cells to generate electronic charges corresponding to the pixels of the image including a subject, and second group circuit cells to generate electronic charges corresponding to an amount of light coming from the subject, the electronic charges further being converted to a detected value. In the imager, at least one of two operations of halting a generating-action of the electronic charges in the first group circuit cells and discharging the electronic charges from the first group circuit cells is performed, when the detected value exceeds a threshold value.Type: GrantFiled: January 17, 2002Date of Patent: August 8, 2006Assignee: Konica CorporationInventors: Jun Takayama, Tetsufumi Takaba, Kyosei Miyata, Takao Hosaka, Takenori Kitada, Koichi Sato, Hiroshi Kibayashi

Publication number: 20010022617Abstract: The present invention concerns a system for recycling an electronic-image recording apparatus such as an electronic camera, etc., which can be used again. The system includes a restricting device to restrict an image-capturing operation under a predetermined condition occurring after use of the electronic-image recording apparatus, a readout section to read a first image signal in the basis of an image signal stored in the electronic-image recording apparatus, a converting section to convert the first image signal, read by the readout section, into a second image signal, and a canceling section to cancel the image-capturing restriction set by the restricting device included in the electronic-image recording apparatus.Type: ApplicationFiled: March 13, 2001Publication date: September 20, 2001Inventors: Tetsufumi Takaba, Jun Takayama, Koichi Sato, Kozue Yogata, Masami Fujita, Masaaki Takasaki, Hiroshi Kibayashi
