Abstract
The invention discloses a system and method for an optical imaging device comprising an image sensor for reading image data from an original slid over the image sensor, a variable power interface for varying an intensity of an illumination source corresponding to the image sensor, wherein the intensity is varied responsive to velocities of the original slid over the image sensor, and a processor for processing the image data.
Claims20
An optical imaging device comprising:
- an image sensor for reading image data from an original slid over said image sensor;
- a variable power interface for varying an intensity of an illumination source corresponding to said image sensor, wherein said intensity is varied responsive to velocities of said original slid over said image sensor;
- and
- a processor for processing said image data.
1 more element
A method of optoelectronically copying an original image comprising the steps of:
- passing said original image over a first optical sensor during said passing;
- calculating a speed of said original image;
- adjusting an exposure timing of said first optical sensor responsive to said calculated speed;
- varying an intensity of light sources associated with said first optical sensor;
- and
- electronically copying said original image using image data obtained by said first optical sensor.
3 more elements
An optical imaging device comprising:
- illumination means for providing illumination to an original to be scanned;
- imaging means for directing light reflected from said original to form an image on an image sensor;
- mounting means for holding said imaging means, said illumination means, and said image sensor in relationship for scanning;
- motion means for providing relative motion between said mounting means and said original;
- measurement means for measuring the speed of said relative motion;
- and
- light control means for varying an intensity of said illumination in response to variation in said speed.
