Abstract: When estimating color for a marker candidate region that is smaller in size than a DeBayer filter, a sever estimates the color of the marker candidate region using HSV average values that are the average values of the hue H, the saturation S, and the brightness V of the marker candidate region, in consideration of the Bayer array of color filters. Furthermore, the server appropriately corrects the HSV average values and converts the pixel format to convert the HSV average values to RGB (RGB average value values), and sets the RGB average values in all pixels of a marker region.

Abstract: An information processing device includes a first processor. The first processor obtains a first positioning result and a second positioning result higher in positioning accuracy than the first positioning result. In response to obtaining the first positioning result, the first processor generates, based on the first positioning result, first information having a content corresponding to the positioning accuracy of the first positioning result as information. In response to obtaining the second positioning result, the first processor generates, based on the second positioning result, second information having a content corresponding to the positioning accuracy of the second positioning result as the information. The second information is different from the first information. The first processor outputs the generated information.
