Abstract

A mobile device comprising a camera and color detection software stored in memory of the mobile device, wherein the color detection application analyzes and displays component colors in a captured image and compares component colors in two such captured images. The color detection application displays component colors in a specific format such as red, green and blue and displays percentage of these colors in each of the compared images. The color detection also provides textual and audio feedbacks of the extent of match between colors of the two images. The two captured images that are to be compared are displayed in split windows. When the captured images are multicolored, the color detection application provides an arrow on these images to identify a specific location and compares the component colors at these locations. Also, an independent electronic device analyzes and displays component colors in a captured image and compares component colors in two such captured images.

Claims

1. A mobile device comprising a camera circuitry, the mobile device further comprising:

at least one memory module;

a color detection software stored in the at least one memory module that supports analysis of colors contained in images captured by the camera circuitry;

the color detection software analyzing color contents in a first image captured by the camera circuitry based on a first color format;

the color detection software analyzing color contents in a second image captured by the camera based on the first color format; and

the color detection software displaying a color content comparison information between the first image and second image.

2. The mobile device of claim 1, wherein the first color format is based on one of the color schemes from the set comprising RGB, YMB, CMYK, pantone matching system and CMB.

3. The mobile device of claim 2 further comprising:

the color detection software displaying the color contents in the first image and the color contents in the second image based on the first color format; and

the color detection software displaying the differences between the first image and second image in terms of the first color format.

4. The mobile device of claim 1, wherein the mobile device advises the user on how close the colors of first image are to the colors of the second image.

5. The mobile device of claim 4, wherein the color detection software displays the first and second images side by side and also provides information on the color content differences between the two.

6. The mobile device of claim 4, wherein the color detection software displays an extent of match between the first image and the second image in words.

7. The mobile device of claim 1, wherein the first and second images contain multiple sections with different colors.

8. The mobile device of claim 7, wherein the color detection software displays red, green and blue color contents from the first and second images, in an identified location.

9. The mobile device of claim 7, wherein the color detection software displays an extent of match between the first and second images, in a given location, employing words.

10. The mobile device of claim 1, wherein the color detection code provides audio feedback regarding the color differences between the first and second images.

11. The mobile device of claim 1, wherein the color detection code calibrates the camera circuitry before being used for comparison of the first image to the second image.

12. The mobile device of claim 1, wherein the camera circuitry is calibrated and a calibration correction is subsequently incorporated into the analysis of the color contents.

13. An electronic device comprising:

an analog image capture mechanism;

an analog to digital converter;

a comparator circuitry;

a display circuitry;

the analog image capture mechanism capturing an image from a given location of an object when triggered;

the analog to digital converter converting the captured image to a digital representation;

the comparator circuitry comparing the digital representation with that of preset reference colors thereby generating a color content information; and

the display circuitry displaying the color content information.

14. The electronic device of claim 13, wherein the color content information is provided employing a color format based on red, green and blue reference colors.

15. The electronic device of claim 14, wherein the electronic device displays the color content information for a given location of an object in terms of red, green and blue colors.

16. The electronic device of claim 14, wherein the electronic device captures one or more images from an object employing the analog image capture mechanism and displays the color content information for the one or more images from the object.

17. A method performed by a mobile device that comprises a camera and a color detection application, the method comprising:

calibrating the camera to determine a color bias and compensating for the color bias;

capturing and storing a first image comprising a first color area;

analyzing and displaying color contents of the first color input area in a preset format;

capturing and storing a second image comprising a second color input area;

analyzing and displaying color contents of the second color input area in the preset format; and

displaying extent of match between the color contents from the first color input area and the second color input area.

18. The method of claim 17, wherein the preset format is based on red, green and blue colors.

19. The method of claim 18 wherein the mobile device displays red, green and blue color contents in the first and second images.

20. The method of claim 17 wherein the first and second images each comprise multiple colored areas and wherein the mobile device displays a color content information of the first and second images in a given common location.
