Patent number: 4547663Abstract: A focus detecting apparatus is disclosed which includes a focusing optical system for forming an object image on a predetermined focal plane and photoelectric devices disposed before and behind the focal plane at substantially equal distances from the plane. The photoelectric devices detect the focus states of the object images formed thereon respectively. The focus state of the object image on the focal plane is detected depending on whether or not the focus states on the photoelectric devices are equal to each other. According to the invention such a focus detecting apparatus further includes a mask for gradually decreasing the quantity of light incident upon the photoelectric devices in the direction away from the center of the incident beam. Under the action of such a mask, the focus states of object images before and behind the predetermined focal plane at substantially equal distances from the focal plane are made approximately equal to each other.Type: GrantFiled: April 5, 1984Date of Patent: October 15, 1985Assignee: Canon Kabushiki KaishaInventors: Nozomu Kitagishi, Shin Yamaguchi, Shinji Sakai, Takao Kinoshita, Takashi Kawabata, Nobuhiko Shinoda, Kazuya Hosoe

Patent number: 4522480Abstract: A battery checking device for cameras of the type having a booster circuit the output of which is fed as electrical power to a load is disclosed. In the case of the camera of the type described, when the battery voltage is checked at the output of the booster circuit, an accurate checking operation cannot be carried out. The present invention, therefore allows the voltage at the input of the booster circuit to be checked. Since another problem is that the booster circuit, after having been actuated, takes a predetermined time before its operation is stabilized, and the value of voltage as sensed during this time does not provide an accurate representation, the present invention provides that checking of that input voltage begins after the elapse of a predetermined time from the actuation of the booster circuit when the operation of the booster circuit becomes stable. Accordingly, it is made possible to achieve always an accurate and reliable battery checking operation.Type: GrantFiled: April 12, 1984Date of Patent: June 11, 1985Assignee: Canon Kabushiki KaishaInventors: Takashi Kawabata, Nobuhiko Shinoda, Shinji Sakai
