    • In a picture reading apparatus, in the pre-scan, an approach is employed to control a CCD line sensor 5 and a film carrying roller 103 so that plural pictures recorded on an optical film 1 are read at a predetermined sampling rate in order from the latest frame to generate frame position data indicating position of left and right ends of frame, etc. Further, in the main scan, an approach is employed such that, in controlling the CCD line sensor 5 and a film carrier 100 so that plural pictures recorded on the optical film are read at a sampling rate higher than the predetermined sampling rate in order from the oldest frame, the reading start and end timings of the CCD line sensor 5 are controlled on the basis of frame position data obtained by the pre-scan. As a result, in this picture reading apparatus, it is possible to precisely obtain picture data of picture of frame in the state where no positional shift takes place. In addition, since the pre-scan is carried out at a low sampling rate, frame position data can be obtained in a short time.
    • 在图像读取装置中,在预扫描中,采用了一种方法来控制CCD线传感器5和胶片承载辊103,使得以预定的采样率从光学胶片1读取记录在光学胶片1上的多个图像 以产生指示帧的左右两端的位置的帧位置数据等。此外,在主扫描中,采用这样的方法,即在控制CCD行传感器5和胶片载体100时,记录多个图像 基于从最早的帧开始按照高于预定采样率的采样率来读取光学薄膜,基于通过预扫描获得的帧位置数据来控制CCD行传感器5的读取开始和结束定时 。 结果,在该图像读取装置中,可以在不发生位置偏移的状态下精确地获得帧图像的图像数据。 此外,由于以低采样率执行预扫描,因此可以在短时间内获得帧位置数据。

    • A digital film processing system and method which utilizes a single imaging station having a single sensor unit. During a first scanning, radiation is applied to the front surface of a frame of developing film and the radiation reflected from the front surface of the film is sensed using a single sensor unit. The film is then flipped or rotated either manually or automatically. During a second scanning, radiation is then applied to the back surface of the same frame of the developing film, and the radiation reflected from the back surface of the film is sensed using the single sensor unit. During another scanning, either before or after the film is flipped, radiation is transmitted through the same frame of the developing film and the transmitted radiation is sensed by the single sensor unit. Then, a single digital image file for the frame is created from the three scannings.

    • Apparatus and method of processing microfiche images. The apparatus includes an unattended low-resolution wide area pre scanning station and an unattended high-resolution line scanning station. The low-resolution station automatically identifies active image areas and borders on a plurality of light passing documents transported in seriatim along a prescan path. The unattended low resolution scanning station generates a plurality of active image area signals indicative of the active image areas and borders in a plurality of light passing documents. The unattended high-resolution line scanning station includes a high-resolution line scanner that responds to the individual ones of said plurality of active image area signals. The high resolution scanning station automatically focuses the high resolution line scanner on only the active image areas of said light passing documents and then converts each scanned document image into a corresponding enhanced digital information signal that is indicative of the image information carried on the scanned document.
