发明名称 IMAGE CAPTURING APPARATUS AND EXPOSURE CONTROL METHOD
摘要 In an image capturing apparatus, a subject image is converted into an image signal, which undergoes automatic correction processing including white balance correction processing, and further undergoes image quality change processing. A first evaluation value indicating a largest value of an R signal, a G signal, and a B signal of the image signal undergone the image quality change processing and a second evaluation value indicating a luminance of the image signal undergone the image quality change processing are detected. A control evaluation value is calculated using weighted average of the first evaluation value and the second evaluation value according to at least one of an amount of image quality changing effect due to the image quality change processing and a reliability of the automatic correction processing, and exposure control is performed based on the control evaluation value.
