Patent number: 5159386Abstract: A system for printing photographs form developed film includes a light receiving element for detecting an image condition, such as the image density or color balance, which is used to control a printing light source. The light from the printing light source projects the photographic image on photographic paper through the developed film. A code reader reads codes printed in the vicinity of the film frame through a line sensor. The codes includes data concerning the photographic mode selected, such as pseudo focal length or a normal photographic mode. The light receiving element detects the image condition only of the area to be printed in accordance with the selected photographic mode and which passes through the developed film and a printing zoom lens.Type: GrantFiled: March 11, 1992Date of Patent: October 27, 1992Assignee: Minolta Camera Kabushiki KaishaInventors: Nobuyuki Taniguchi, Yoshiaki Hata, Yoshinobu Kudo, Manabu Inoue, Takeo Hoda, Hiroshi Ueda
