    Abstract: 在电子胶片显影技术中,需要在显影过程中用光束对胶片(101)进行多次扫描。在感光乳剂中包含有产生显影颗粒用的乳白色卤化银物质,所以光束会由感光乳剂处反射回来。未显影的卤化物层具有一定的深度,足以将由光源发射来的光子散射回去。这一深度在通常使用的红外线光源的相干长度范围之内,所以会在扫描图象中产生干涉噪音。本发明是在感光乳剂溶胀之后并在银颗粒被显影之前实施预扫描,并逐个象素地对随后的扫描图象实施归一化处理,从而可以消除相干斑点和其它缺陷。

    Abstract: An apparatus for digitally archiving analog film images includes a support surface (58) on which an analog film image may be supported, and a digitizer (92) that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light (84) transilluminates the film image and projects it toward the digitizer through an objective lens (94) which focuses the image. The positions of the digitizer and the lens along the Z axis are adjustable so that the size of the image projected onto the digitizing means can be varied. For example, it is possible to move the digitizer and objective lens between a range of enlarging positions in which the lens is closer to the film image than to the digitizer, and a range of reducing positions in which the lens is further from the film image than from the digitizer so that the film image may be either enlarged, reduced or reproduced at the same size before being sensed and converted into digital data.

    Abstract: A film video player (10) has film gates (14, 15) for mounting photographic film (F, F'). An imager has a lens (L) for projecting at least a portion of a film frame image from the film onto a sensor (S). The sensor converts an image to a video signal for video display. A zoom carriage (25) changes the magnification of the image with respect to the film frame image. A scan carriage (65) translates the sensor with respect to the film frame image in one axis, and a gear assembly (90) translates the sensor along a perpendicular axis as well as rotating it.

    Abstract: A method for controlling a scanning apparatus for scanning a continuously moved object (3) includes seizing the actual momentary position of the moving object (3), and controlling the time instant or period in which image information is captured by the scanning devices (6) in dependence of the actual momentary position of the object (3). The scanning apparatus in which the method is used includes a multiplicity (6) of line scanning devices arranged adjacent to each other in the direction of the movement of the moved object (3). Each of the line scanning devices has a multiplicity of pixels that are arranged adjacent to each other in a direction across a path along which the object (3) is moved. The pixels of the line scanning devices accumulate charges according to the amount of incident light. A controlling means (7) is provided for transferring the charges accumulated in individual pixels to pixels in the adjacent line scanning device in synchronism with direction of the movement and the speed of the moving object (3). The object (3) is illuminated or transilluminated by a light source (4).
