发明名称 FOCUS DETECTION APPARATUS
摘要 A focus detection apparatus that measures, in advance, and stores shading coefficients for light sources of different types, and in a focus detection operation, generates light source information for determining a light source that irradiates an object based on outputs from a plurality of photometry sensors with different spectral characteristics and switches the shading coefficient of a focus detection sensor among shading coefficients stored according to the light source information.
