Patent number: 5732294Abstract: A still camera (electronic still camera, silver halide still camera, etc.) is provided that performs microphotography without blurring caused by inherent camera vibrations. The still camera includes a front curtain drive assembly that starts a front curtain of the mechanical shutter assembly substantially simultaneously with the driving of a quick-return mirror. A time-monitoring device monitors the passage of time until vibrations caused by the quick-return mirror moving to a position outside of the optical axis position are eliminated. The time-monitoring device can further monitor the time until vibrations caused by driving the front curtain are eliminated. When the time-monitoring device determines that the time required to eliminate the vibrations has elapsed, an exposure time control device starts the electronic shutter assembly.Type: GrantFiled: February 3, 1997Date of Patent: March 24, 1998Assignee: Nikon CorporationInventors: Koichiro Kawamura, Ryo Uehara

Patent number: 4532558Abstract: A picture recording apparatus is capable of easily confirming the quality or recorded condition of a still picture signal stored in a memory device. The memory device includes a plurality of memory units and whether the still picture signal corresponding to one frame and stored in the memory device is "good" or "bad" is discriminated by a discriminator before the next photographing. Where the apparatus includes an erase head, if the discrimination results in "bad", the content of the corresponding memory unit is erased and the content resulting from the next photographing is stored automatically in the corresponding memory unit. If the discrimination results in "good" in the apparatus or if the apparatus has no erase head, after the discrimination the content resulting from the next photographing is automatically stored in the next memory unit.Type: GrantFiled: April 21, 1983Date of Patent: July 30, 1985Assignee: Nippon Kogaku K.K.Inventors: Tadashi Oota, Koichiro Kawamura
