Abstract
A backlit scanner uses an exposure control device to adjust the amount of backlight that reaches the vicinity of the transmissive medium being scanned by the scanner. In this way, the amount of backlight can be controlled on a scan-by-scan basis, depending upon exactly how much backlight will lead to optimal image quality. In some preferred embodiments the backlit scanner is designed to scan x-ray images and/or other transmissive-medium medical images.
Claims9
A backlit scanner system for scanning images printed on a transmissive medium, the scanner comprises:
- a scanner to create an image based on light received from the transmissive medium when the transmissive medium is scanned;
- and
- a backlight assembly positioned on the scanner to backlight the transmissive medium, the assembly comprising a light source and an exposure control device which enables the user to adjust the intensity of the light source to optimize the quality of the scanned image.
A backlight assembly comprising a light source and an exposure control device which enables the user to adjust the intensity of the light source transmitted from the backlight assembly.
A method of scanning an image on a transmissive medium comprising:
- (a) providing a backlit scanner comprising a scanner to create an image based on light received from the transmissive medium when the transmissive medium is scanned;
- and
- a backlight assembly positioned on the scanner to backlight the transmissive medium, the assembly comprising a light source and an exposure control device which enables the user to adjust the intensity of the light source to optimize the quality of the scanned image;
- (b) placing a transmissive medium comprising an image in the scanner;
- (c) performing a preliminary scan on the transmissive medium to obtain preliminary scanning results;
- (d) subsequent to step (c), adjusting the exposure control device to control the amount of backlighting, in response to observed preliminary scanning results;
- and
- (e) subsequent to step (d), performing a re-scan on the transmissive medium.
