Abstract: In electronic film development, a film (101) is scanned, using light, multiple times during development. The light is reflected from an emulsion containing milky undeveloped silver halide embedded with developing grains. The undeveloped halide layer has a finite depth over which photons from a light source scatter backward. This depth is within the range of the coherency length of infrared sources commonly used in electronic film development, causing coherency speckle noise in the scanned image. A prescan made after the emulsion swells, but before the silver grains develop, normalizes subsequent scans, pixel by pixel, to cancel coherency speckle and other defects.

Abstract translation: 在电子胶片显影中，在显影过程中，多次使用光来扫描胶片（101）。 光从含有乳白色未显影的卤化银的乳液中反射，该卤化银嵌入显影晶粒。 未显影的卤化物层具有有限的深度，来自光源的光子向后散射。 该深度在电子薄膜显影中通常使用的红外源的相干长度的范围内，引起扫描图像中的一致性斑点噪声。 在乳液膨胀之后，但在银颗粒发展之前制成的预胶化剂逐渐对随后的扫描进行逐一归一化，以消除相干性斑点和其它缺陷。

Abstract: A plurality of color photographic images that have been captured on a continuous color photographic film strip are pre-scanned at low resolution and then rescanned at high resolution by an opto-electronic scanning device and processed for storage as a plurality of digitized images in a digital imagery data base. The film strip contains notches to spatially locate pre-scan frame data during rescan. During pre-scan the film strip is translated past an opto-electronic scanner in a first direction to obtain a plurality of first digitally encoded images. During high resolution rescan, the film strip is translated in the reverse direction. The high resolution imagery data is mapped into image storage memory on the basis of the contents of respective first digitally encoded images. During the rescan the mapping process is calibrated on the basis of information contained on the film strip other than the notches, such as detected interframe gaps and a correlation of low resolution and high resolution frame 'fingerprints'.

Abstract: Bi-directional multi-resolution scanner (10) having software/firmware for 1- to 2-pass high resolution scanning, enabling the scanner to capture and render image data both the standard direction, top (28) to bottom (34) pass, as well as the return direction, that is, bi-directional scanning, in contrast to prior art scanners which return to the start position after each pass without reading (scanning). Typical current B & W scanning of an 8 1/2 x 11'' image at 600 dpi takes a total time from start to reload to the next image of on the order of 42-67 seconds. In contrast, the inventive system scans and displays the high resolution image in about 37 seconds, some 7 - 30 seconds faster than a conventional scanner. In multiple image scanning, since the time for the two return passes (36) and the preview pass is eliminated, the productivity is increased from 20 to 300 % or more. Since multiple non-scan return passes are eliminated, the inventive system is also a substantial improvement for limited power bus devices.

Abstract: The invention relates to a method for digitally detecting a photographic film (12) comprising a number of frames. The inventive method comprises the following steps: during a pre-scanning, at least one film pre-scanning section is projected onto a scanning element (18) used for carrying out the pre-scanning, whereby data of the film scanning section is detected by the scanning element (18). To this end, at least one characteristic quantity which is relevant to a subsequent principal scanning is ascertained from the detected data. During a principal scanning, at least one film principal scanning section is projected onto the scanning element (18), which was already used during the pre-scanning, while taking the at least one characteristic quantity into account. During pre-scanning, the film (12) is gradually advanced independent of the position of the frames and is scanned when at rest. During the pre-scanning, positioning data permanently assigned to the frames is detected for the principal scanning.

Abstract: 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.
