Abstract
Systems and methods use a digital microform imaging apparatus for sensing an image mark on the microform containing the image of a document. The use of an area sensor with an adjustable region of interest can be used to improve the detection speed of image marks as a roll of microform is being transported.
Claims26
A method for sensing an image mark on a microform using a digital microform imaging apparatus, the apparatus having an area sensor, the method comprising the steps of:
- sensing at least one image mark on the microform using the area sensor;
- and
- adjusting an area sensor region of interest.
A method for sensing an image mark on a microform using a digital microform imaging apparatus, the apparatus having an area sensor, the method comprising the steps of:
- sensing at least one image mark on the microform using the area sensor;
- and
- determining at least one dimension of the image mark on the microfilm.
A method of sensing an image mark on a microform using a digital microform imaging apparatus, the apparatus having an area sensor, the method comprising the steps of:
- sensing at least one image mark on the microform using the area sensor;
- and
- detecting a format of the image mark.
A digital microform imaging apparatus, the apparatus comprising:
- an area sensor having a defined region of interest;
- and
- a film guide assembly for retaining the microform on a film path, the film path including an optical path,
- wherein the area sensor region of interest is configured to be adjustable.
