发明名称 Image pickup apparatus
摘要 In imaging using a linear log sensor and an auxiliary light source, an image pickup apparatus capable of preventing an excess of exposure and suppressing the influence on the brightness of the overall screen even if the distances of a plurality of photographic subjects are different from each other within the arrival range of strobo light is provided. In an image pickup apparatus 1 , an image pickup device 4 , an irradiation unit 6 for irradiating light at time of picking up an image of a photographic subject, and an inflection point changing unit 25 for changing an inflection point which is a boundary between a linear area and a logarithmic area so as to prevent an output signal of the image pickup device 4 from saturation within the brightness range of the photographic subject and to use the logarithmic area in priority are installed.
