Measurement error of sparkle contrast was investigated by using Image Subtraction Method. The statistical error was suppressed enough when the sampling points were around 100×100 pixels. The parameter as an indicator of both statistical error by insufficient sampling pixels and low- frequency luminance variation within the sampling field was proposed.
