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 objective is to efficiently store images to be used as training data. A server determines an image area (first image area) including an image of a marker or the like, in a captured image corresponding to image data acquired by image capturing by a camera, for example. The server then determines an image area (second image area) of a moving body (for example, forklift) equipped with the marker or the like. The server generates and stores training data corresponding to the second image area. The training data will be used for machine learning later.

Abstract: A position coordinates setter sets position coordinates being coordinates of an image region of an LED in an image. An image region determiner determines whether or not an image region having a predetermined luminance value is present at the position coordinates. If an image region having the predetermined luminance value is not present at the position coordinates, the image region determiner determines whether or not the image region at the position coordinates is overexposed or underexposed, and the exposure controller continues setting, if the image region is overexposed, the exposure time shorter by one degree at a time until the luminance value of the image region at the position coordinates becomes the predetermined luminance value, and continues setting, if the image region is underexposed, the exposure time longer by one degree at a time until the luminance value of the image region at the position coordinates becomes the predetermined luminance value.

Abstract: An image area detector detects a high-luminance image area having a luminance value equal to or higher than a predetermined value, having a size equal to or larger than a predetermined size, and including two or more high-luminance subject images disposed adjacent to or overlapping with each other, from an input image frame. The enlargement controller controls the detected high-luminance image area to be enlarged and displayed. If any instruction to designate a subarea within a rectangular border surrounding the enlarged high-luminance image area is provided from the user, the position coordinate setter converts the coordinates of the subarea into the coordinates before the enlargement, and stores the converted coordinates into the memory as the coordinates of the LED serving as a light source that transmits information.
