Title:
COLOR ESTIMATION DEVICE, COLOR ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/020355
Kind Code:
A1
Abstract:
When estimating color with respect to a marker candidate region that is smaller in size than a DeBayer filter, a server estimates the color of the marker candidate region using HSV average values, which are average values for the hue H, saturation S, and brightness V of the marker candidate region, in consideration of the Bayer array of a color filter. Furthermore, the server appropriately corrects the HSV average values and converts the pixel format, thereby converting the HSV average values to RGB (RGB average values), and sets the resultant RGB average values in all pixels of a marker region.
