The present invention determines a position of a spot in image data obtained by imaging detection intensity in a carrier, extracts a pixel group corresponding to the spot, calculates a ratio or a difference between a median value of the detection intensity of the extracted pixel group and a median value of the detection intensity of the pixel group excluding a certain top proportion of and/or a certain bottom proportion of pixels, and determines quality of reliability based on the calculated ratio or difference and a certain reference value. |
