摘要： A circuit for color space conversion and associated method compresses a portion of an xvYCC color space exceeding an sRGB color space into the sRGB color space via a simplified circuit design when a conversion from the xvYCC color space to the sRGB color space is performed, thereby improving visual effects. The circuit for color space conversion includes a conversion unit converting a pixel signal from the xvYCC color space to the sRGB color space. During the conversion, the conversion unit generates a pixel component on each dimension of the sRGB color space, and compresses the pixel component to output a compressed pixel component when a value of any pixel component is in a compression interval. The compressed pixel component does not exceed a defined range on a corresponding dimension of the sRGB color space.

摘要： A focal position detecting apparatus, for detecting a focusing condition and a tilting condition of an object, includes a planar beam generating module, an optical system, an optical sensor and a cylindrical lens. The planar beam generating module generates a planar light beam along a first path. The optical system is disposed on the first path, wherein the planar light beam, reflected by the object, passes through the optical system along a second path. The optical sensor is disposed on the second path. The cylindrical lens is disposed on the second path between the optical system and the optical sensor and an axis of the cylindrical lens is perpendicular to the second path. The planar light beam passes through the optical system and the cylindrical lens along the second path, before it is incident on the optical sensor to form a linear light spot for determining defocusing degree.
