摘要: A method of acquiring image signal and an acquisition device are proposed. The includes steps: measuring brightness signals gray-scale switched images in a sample gray scale, nonlinear interpolating the scale to acquire full images. is cubic spline interpolating. present invention interpolates images, thus it efficiently acquires different scales.
