A method of determining a solder paste height of solder paste printed on a circuit board, the method including obtaining a two-dimensional image of the circuit board which is captured from above a solder printed surface, and determining the solder paste height corresponding to a pixel value of each of pixels of the two-dimensional image, based on height information which defines a relationship between the pixel value and the solder paste height, the pixel value being a value representing at least one of luminance of red in a RGB color model, luminance of green in the RGB color model, luminance of blue in the RGB color model, hue in a HSI color model, saturation in the HSI color model, and intensity in the HSI color model.
