    • One aspect of the invention is a method for locating an unexposed region of film. The method includes the step of illuminating film with a light source while the film has developing chemical applied thereto, the film comprising at least two edges along an x direction perpendicular to a y direction parallel to a surface of the film. The method also includes the step of identifying an unexposed region of the film as a region containing ones of a first plurality of columns of the film, the columns disposed generally in the y direction and captured using at least one sensor operable to capture light reflected from the film, and wherein a representative value for each of the ones of first plurality of columns exceeds a threshold.

    • 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.
    • 具有用于1到2遍高分辨率扫描的软件/固件的双向多分辨率扫描器(10),使得扫描仪能够捕获和渲染标准方向(28)到底部(34)的图像数据, 以及返回方向,即双向扫描,与现有技术的扫描仪相比,在每次通过之后没有读取(扫描)的情况下返回到开始位置。 在600 dpi的8 1/2 x 11“图像的典型当前B&W扫描将从开始到重新加载到42-67秒的下一个图像的总时间。 相比之下,本发明的系统在大约37秒内扫描并显示高分辨率图像,比常规扫描仪快7到30秒。 在多次图像扫描中,由于消除了两次返回时间(36)和预览通过的时间,所以生产率从20增加到300%以上。 由于消除了多个非扫描返回通道,本发明的系统也是有限的功率总线设备的实质性改进。
