Abstract:
1. An imaging apparatus comprising: an acquiring unit configured to acquire a representative value of a luminance level in a main object area and a plurality of representative values of luminance levels in peripheral areas of the main object area in an image obtained by an imaging unit; a calculation unit configured to calculate a plurality of relative values between the respective plurality of representative values of luminance levels in the peripheral areas and the representative value of a luminance level in the main object area, which are acquired by the acquiring unit; a setting unit configured to set intensity of knee processing based on the plurality of relative values calculated by the calculation unit; and a knee processing unit configured to execute the knee processing on an image acquired by the imaging unit according to the intensity set by the setting unit, wherein the calculation unit executes a square calculation for a difference value between each of the relative values in each of the surrounding areas and the representative value in the main object area as the relative value.
