Abstract
A visibility support apparatus includes a light receiving unit receiving reflected light from an object to generate a signal for an image for each of wavelength bands, a wavelength selecting unit to set, in the image for at least one wavelength band, a set of those of pixels with comparable signal intensities which define the largest occupied area to be a reference area and to compare, for each of identification target pixels not included in the reference area, a value of the pixel in the image for each wavelength band with a pixel value of the reference area to select at least two wavelength bands which are effective for detecting the object, and a display unit to group the identification target pixels based on a wavelength band combination selected for each identification target pixel and display an image in which the object is distinguishably shown based on the grouping.
