Abstract:
1. A bright line plot processing method of plotting a bright line which starts from a pixel at a bright point in a predetermined area of an image to be processed, comprising the steps of: a first bright line plotting step of generating an image of the bright line from preliminary data of a pixel using a predetermined bright line definition format; a second bright line plotting step of setting either one of data of the pixel at the bright point of the image to be processed or data of a white pixel corresponding to a luminance of the bright point as data of the pixel at a starting point of the bright line; a third bright line plotting step of calculating data of each pixel in an area where the image of the bright line is plotted by performing weighting addition of 1) the data of each pixel corresponding to the area where the image of the bright line in the image to be processed is plotted and 2) the data of the pixel at the starting point of the bright line at an attenuation rate, where a predetermined attenuation rate is applied to at least one of the pixel positioned farther from the starting point of the bright line in a lengthwise direction along a center line and the pixel position farther in respective widthwise directions; and a fourth bright line plotting step of plotting the bright line on the image to be processed on a basis of the data of the pixels for the bright line calculated in said third bright line plotting step.
