The luminance and chromaticity of monitors are measured through color luminance meters. Small-field optical filter color luminance meter is widely used in production line for its low-cost. Image color luminance meter

as a new product

is also a kind of optical filter color luminance meters. But it is large-field because of the different detector. Its structure

principle and performance are also different. Making performance contrast between these two kinds of optical filter color luminance meters helps estimating the image color luminance meter's quality. This paper makes a performance contrast between the two kinds' representative through principle analysis and experiment. It turns out that the performance of the image color luminance meter is no worse than the small-field optical filter color luminance meter.
