Abstract
Color adjusting apparatus and method for a light source. A reflector of a required color is added to a light source of a scan module, a plating film of the required color is formed on a lens, or the lens is dyed with the required color. Or alternatively, the color of the light source is directly changed into the required color. As a result, the inconsistent intensities for the light in the primary color, red, green and blue output from the charge-coupled device caused by different brightness of the light source, different wavelength transmission of the lens, and different light sensitivity of the charge-coupled device is improved.
Claims25
A method comprising:
- providing a document scanner having a light source configured to radiate a document to produce an imaging light, a reflection mirror set in an optical path of the imaging light and configured to reflect the imaging light, an optical detector configured to receive the imaging light reflected by the reflection mirror set, and a lens set comprising at least one lens disposed in the optical path between the optical detector and the reflection mirror set;
- detecting a portion of the imaging light having insufficient intensity outputted by the optical detector;
- configuring the at least one lens with a color effective to enhance the intensity of the portion of the imaging light detected to have insufficient intensity;
- and
- passing the imaging light through the at least one lens of the lens set.

An optical scan module, comprising:
- a light source configured to radiate a document to obtain an imaging light;
- a reflection mirror set disposed in an optical path of the imaging light and configured to reflect the imaging light;
- a lens set disposed in the optical path of the imaging light and configured to allow imaging light reflected from the reflection mirror set to pass therethrough, the lens set comprising at least one lens;
- and
- an optical detector disposed in the optical path of the imaging light and configured to receive the imaging light that passes through the lens set,
- wherein responsive to a determination that an output of the optical detector indicates that a portion of the imaging light has an insufficient intensity, the at least one lens is configured with a color, selected from a group consisting of red, green, and blue colors, to enhance the intensity of the portion of light having the insufficient intensity.

- means for reflecting the imaging-light disposed in an optical path of the imaging light;
- means for allowing the imaging light reflected by the means for reflecting to pass therethrough, the means for allowing disposed in the optical path of the imaging light and comprising at least one lens having a color, selected from a group consisting of red, green, and blue colors, to enhance the intensity of the light of the imaging light having the first color;
- and
- means for receiving the imaging light that passes through the means for allowing, the means for receiving disposed in the optical path of the imaging light.
2 more elements
A scanner, comprising:
- a platform configured to receive a document;
- an optical scan module having:
- a light source configured to radiate the document to obtain an imaging light;
- a reflection mirror set, disposed in an optical path of the imaging light and configured to reflect the imaging light;
- a lens set disposed in the optical path of the imaging light and configured to allow light reflected from the reflection mirror set to pass therethrough, the lens set comprising at least one lens having a color selected from a group consisting of red, green, and blue colors;
- and
- an optical detector disposed in the optical path of the imaging light and configured to receive the imaging light that passes through the lens set,
- wherein the selected color is selected, in response to a determination that the imaging light includes a portion with insufficient intensity, to enhance the intensity of the portion of the imaging light with insufficient intensity;
- and
- a driving mechanism configured to drive the optical scan module along the platform to scan the document.
