    • A film image input system is disclosed which provides an increased degree of feedom of design thereof, can be reduce the size and costs thereof, and can execute a trimming operation with ease. The film image input system forms an image of a developed still photo film 134 on a light receiving surface of an image pickup element 140 through a zoomable taking lens 138 and outputs to a monitor TV an image signal photo-electrically converted by the image pickup element 140 to thereby reproduce the film image on the screen of the monitor TV. The film image input system comprises at least one mirror 137 interposed between the photo film 134 and taking lens 138 for bending the optical axis of the taking lens 138, a mirror drive mechanism 168 for inclining the mirror 137 in all directions, and an operation part 170 for driving the mirror drive mechanism 168 in order to execute a desired scanning. This allows the system to be made compact and increases the freedom of design of the system.

    • A scanner mechanism having a multi-position lens assembly for capturing images resident on an original includes an electronic camera for capturing the images and providing an image signal therefrom and a base assembly having a camera housing which supports the camera for movement relative to an optical axis in order to define plural fields of view. A lifting cam is mounted for pivotal movement from the base assembly, pivoting at one end thereof in spaced relation to the camera and engaging the camera at the other thereof for movement relative to the base assembly to define the plural fields of view, the lifting cam further having a contour cam surface on one side thereof. A slide is movable in relation to the base assembly and supports at least two lens assemblies in spaced relation relative to the optical axis of the camera. Since the slide has a surface element movable therewith for engaging the contour cam surface of the lifting cam, the slide is moved until the lifting cam positions the camera relative to a selected lens assembly in the optical axis of the camera.

    • An image sensing apparatus reliably indicates an image sensing area regardless of the size of an object. In the apparatus, illumination units 14 irradiate spot lights 36 on a base 7 to indicate an image sensing area 37 for sensing an original 6 by a camera head 9. The image sensing area indicated by the spot lights 36, irradiated from laser devices 33 of the illumination units 14, attached to the camera head 9, is corresponding to the length/width ratio of the image screen of a monitor 3. A luminance signal level, stored in a memory of a system controller 15, on image sensing the base, is compared with the level of a luminance signal from an image sensing device 25, and when the signal levels do not coincide, it is determined that an original exists on the base. Further, the system controller 15 independently changes first to fourth spot lights 110 to 113 irradiated from the first to fourth illumination units.

    • A dithered image reconstruction system and method that compensates for inter-detector errors in a manner that does not adversely affect detection of small-amplitude images in the presence of a very bright large-amplitude background. An overlapping dither pattern is employed in a detector array (103), and outputs generated by individual detectors (302) are adjusted in an iterative fashion to hold all outputs for a particular detector substantially constant, while allowing each set of outputs for each image section to converge on a solution. The system and method do not substantially distort the received signal, nor do they fail when the image characteristics have little spatial variation, such as when a large target area is being detected.
    • 一种抖动图像重建系统和方法,其在以非常明亮的大振幅背景存在的情况下以不会不利地影响小振幅图像的检测的方式来补偿检测器间误差。 在检测器阵列(103)中使用重叠抖动图案,并且以迭代方式调整由各个检测器(302)产生的输出,以保持特定检测器的所有输出基本上恒定,同时允许每个图像部分的每组输出 融合在一个解决方案上。 系统和方法基本上不会使接收的信号失真,并且当图像特征具有很小的空间变化时,例如当检测到大的目标区域时它们也不会失效。
