Abstract
Systems and methods use a digital microform imaging apparatus for sensing an image mark on the microform containing the image of a document.
Claims20
A method for sensing an image mark on a microform using a digital microform imaging apparatus, the apparatus including an area sensor having a pixel array, the area sensor defining an optical axis, the method comprising the steps of:
- defining an image mark region of interest within the area sensor that is a subsection of pixels within the pixel array;
- receiving the image mark within the image mark region of interest;
- and
- sensing the image mark on the microform.
A digital microform imaging apparatus configured to sense a microform having a plurality of images and a plurality of image marks corresponding to the plurality of images, the digital microform imaging apparatus comprising:
- an area sensor having a pixel array, the area sensor defining an optical path, the area sensor configured to sense the plurality of images and the plurality of image marks;
- wherein a subsection of the pixel array defines an image mark region of interest in which the plurality of image marks are sensed;
- wherein the image marks correspond to at least one of a batch number, a file number, or a page number within the microform;
- and
- a computer interface through which an operator can select an image of the plurality of images to be displayed on a screen by entering at least one of the batch number, the file number, or the page number of the microform on which the image is located.
A method for locating an image on a microform using a digital microform imaging apparatus, the apparatus having an area sensor with a pixel array defining an optical path, the method comprising:
- receiving at least one of a batch number, a file number, or a page number associated with an image mark and an image on the microform;
- using a subsection of the pixel array defining a region of interest, sensing the image mark on the microform;
- and
- displaying the image on a screen.
