Abstract: In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.

Abstract: The invention relates to precision measurement technology, specifically a high-sensitivity three-dimensional topography recovery method using dual-channel differentiation. Enhancing a traditional microscopic imaging system, a beam splitter is added between the objective lens and tube lens. This creates an additional light path equipped with a tube lens and camera identical to the original but with a slightly different distance to the camera. During axial scanning of the object, focusing evaluation function curves for each pixel are calculated from images captured by both cameras. The curves from the two cameras show more significant changes near the optimal focusing depth, improving system sensitivity. This method enhances sensitivity by hardware-fixed differentiation of the focusing evaluation function, while maintaining high scanning efficiency and flexible configuration.
