    • A picture reader in which frame position data showing the positions of left and right ends of frames are generated by controlling a CCD line sensor (5) and film carrying roller (103) so that a plurality of pictures recorded on an optical film (1) can be successively read at a prescribed sampling rate from the latest frame at pre-scanning time. In the course of main scanning, the picture reader controls the read starting timing and read ending timing of the sensor (5), which are controlled based on the frame position data obtained at the pre-scanning time, at the time of controlling the sensor (5) and a film carrier (100) so that the plurality of pictures recorded on the optical film can be successively read at a sampling rate higher than the above-mentioned prescribed sampling rate from the oldest frame. As a result, the picture reader can accurately obtain the picture data of the pictures in the frames without causing any positional deviation. Since the prescanning is made at a lower sampling rate, the frame position data can be obtained in a short time.
    • 通过控制CCD线传感器(5)和胶片承载辊(103),使得记录在光学胶片(1)上的多张图像,产生表示帧的左右端位置的帧位置数据的图像读取器, 可以在预扫描时间从最新帧以规定的采样速率依次读取。 在主扫描的过程中,图像读取器控制在控制传感器(5)时基于在预扫描时间获得的帧位置数据而被控制的传感器(5)的读取开始时间和读取结束定时 (5)和胶片载体(100),使得可以从最早的帧以高于上述规定采样率的采样率连续读取记录在光学膜上的多个图像。 结果,图像读取器可以准确地获得帧中的图像的图像数据而不引起任何位置偏差。 由于以较低采样率进行预扫描,所以可以在短时间内获得帧位置数据。
