    • A film scanner is capable of reading an image formed on a film in accordance with a photographing mode recorded in each frame of the film. In this film scanner, an image formed in each frame of a film held by a film holder is projected onto a linear image sensor by a focusing optical system to read the image with the linear image sensor. A magnetic information detection unit detects magnetic information recorded in each frame of the film, and a system controller identifies a photographing mode of each frame of the film. In accordance with the identified photographing mode, an image read area of each frame is set and a subscanning motor is driven in accordance with this image read area. The subscanning motor is driven in the area outside of the image read area at a faster speed than in the image read area. Therefore, a read time can be shortened as compared to the case wherein all frames are read in the broadest image read area. Trimming works can be omitted.
    • 电影扫描器能够根据记录在胶片每帧中的拍摄模式来读取形成在胶片上的图像。 在这种胶片扫描器中,由胶片保持器保持的胶片的每帧中形成的图像通过聚焦光学系统投射到线性图像传感器上,以用线性图像传感器读取图像。 磁信息检测单元检测记录在胶卷每帧中的磁信息,系统控制器识别胶片每帧的拍摄模式。 根据识别的拍摄模式,设置每帧的图像读取区域,并根据该图像读取区域驱动副扫描电动机。 副扫描电动机以比图像读取区域更快的速度在图像读取区域外部的区域中被驱动。 因此,与在最宽的图像读取区域中读取所有帧的情况相比,可以缩短读取时间。 修剪作品可以省略。
