摘要：
The present invention relates to a focus control apparatus and a culture observation apparatus that enables simple and reliable detection of a focusing position of an objective lens on a subject and with certainty.
When a focusing position of the objective lens on a culture medium drop D11 in a culture container 61 is detected, the culture observation apparatus selects an area, which includes an edge portion of the culture medium drop D11 and does not include an area located within a predetermined distance from the edge of the culture container 61, as an AF area which is to be a target of detecting the focusing position of the objective lens on the culture medium drop D11. Then the culture observation apparatus detects the focusing position on the culture medium drop D11 based on an observation image of the AF area. By detecting the focusing position as a targeting area that is different from an area which is near the edge of the culture container 61 and where illumination unevenness is generated, the detection accuracy can be improved. The present invention can be applied to a culture observation apparatus.
