A new method of DSC's imaging luminance measurement based on HDR image processing is proposed.The time scale exposure series of LDR images to compose a high dynamic range image are used in the method.Then the tristimulus value is calculated from the RGB output by using the color space transformation.Finally the estimated value of luminance is computed by using the calibration coefficient of the digital camera optic-electric conversing function.The luminance measurement results in a exterior test experiment have shown the approach's effectiveness.
