COLOR PATTERN EXTRACTING DEVICE AND COLOR PATTERN EXTRACTING PROGRAM

摘要

[PROBLEMS] An object pattern can be correctly extracted with reference to a registered color even if the color of the object pattern is varied due to mix with the background color. [MEANS FOR SOLVING PROBLEMS] Installed in an HD (20) of a color pattern extracting device (10) is a color pattern extracting program (21) including a learning module (22) having a function of determining a correction parameter used to convert the pattern color acquired when a specific color pattern is displayed on an arbitrary background color into a color acquired when the specific color pattern is displayed on a basic background color by using two images showing the specific color pattern displayed on different background colors and an extracting module (23) for separating the inputted image into the pattern and the background, acquiring the colors of the pattern and the background, converting the object pattern color into a color estimated when the object pattern color is displayed on the basic background color by using these values and the correction parameter acquiring by the learning module (22), and extracting a pattern matching the basic pattern color from the converted object patterns.
