Abstract

A hand-held printer is disclosed. The hand-held printer includes an image sensor configured to determine a color having plurality of color components associated with a print medium, an image processing module configured to process image data into a plurality of color layers; and a print module configured to receive information related to the plurality of color components from the image sensor and information related to the plurality of color layers from the image processing module. The print module being configured to enhance at least one of the plurality of color layers based on at least one of the corresponding plurality of color components associated with the print medium.

Claims

1. A controller comprising:

an interface configured to;

receive background color data corresponding to a background color of a print medium sensed from an image sensor, and

receive digital image data that includes information on a plurality of colors included in the digital image data;

wherein the controller is configured to;

compare the background color data with the digital image data;

correlate the background color of the print medium with the plurality of colors included in the digital image data based on the comparison, and

ignore at least part of the digital image data based on the correlation in order to conserve a printing substance.

2. The controller of claim 1, wherein the background color of the print medium and the plurality of colors included in the digital image data are represented in terms of a red-green-blue (RGB) color or a cyan-magenta-yellow-black (CMYK) color.

3. The controller of claim 1, wherein the controller is configured to compare the background color data with the digital image data in order to determine a relationship that identifies a similarity in color between the background color of the print medium and the plurality of colors included in the digital image data.

4. The controller of claim 3, wherein the controller is configured to ignore at least a part of the digital image data by utilizing a background color of the print medium in place of a color included in the digital image data in response to determining the background color of the print medium is similar to the color included in the digital image data.

5. The controller of claim 1, wherein the controller is configured to ignore at least a part of the digital image data by utilizing a background color of the print medium in place of a color included in the digital image data in response to determining the background color of the print medium is similar to the color included in the digital image data.

6. The controller of claim 1, wherein the plurality of color layers includes at least a red color layer, green color layer, or blue color layer.

7. The controller of claim 1, wherein the plurality of color layers includes at least a black layer or white layer.

8. The controller of claim 1, wherein the plurality of color layers includes at least a hue, saturation, or brightness color layer.

9. The controller of claim 1, wherein the background color of the print medium and the plurality of colors included in the digital image data are correlated while the printing operating is performed.

10. A controller implemented method for modifying digital image data, comprising:

receiving background color data corresponding to a background color of a print medium sensed from an image sensor;

receiving digital image data that includes information on a plurality of colors included in the digital image data;

comparing the background color data with the digital image data;

correlating the background color of the print medium with the plurality of colors included in the digital image data based on the comparison, and

ignoring at least part of the digital image data based on the correlation in order to conserve printing substance.

11. The controller implemented method of claim 10, wherein the background color of the print medium and the plurality of colors included in the digital image data are represented in terms of a red-green-blue (RGB) color or a cyan-magenta-yellow-black (CMYK) color.

12. The controller implemented method of claim 10, wherein comparing the background color data with the digital image data comprises determining a relationship that identifies a similarity in color between the background color of the print medium and the plurality of colors included in the digital image data.

13. The controller implemented method of claim 12, wherein ignoring the digital image data comprises utilizing a background color of the print medium in place of a color included in the digital image data in response to determining the background color of the print medium is similar to the color included in the digital image data.

14. The controller implemented method of claim 10, wherein the plurality of color layers includes at least a red color layer, green color layer, black layer, white layer or blue color layer.

15. The controller implemented method of claim 10, wherein the plurality of color layers includes at least a hue, saturation, or brightness color layer.

16. A non-transitory computer readable storage medium having controller executable instructions to:

receive background color data corresponding to a background color of a print medium sensed from an image sensor;

receive digital image data that includes information on a plurality of colors included in the digital image data;

compare the background color data with the digital image data;

correlate the background color of the print medium with the plurality of colors included in the digital image data based on the comparison, and

ignore at least part of the digital image data based on the correlation in order to conserve printing substance.
