    • An imaging apparatus includes a histogram shape determination unit that acquires a histogram of luminance values from video captured by an image capturing unit and determines whether or not the captured video is a night scene from the shape of the histogram. The imaging apparatus also includes a point light source determination unit that acquires the maximum value of contrast for each horizontal line in the video as a line evaluation value and determines whether the captured video is a night scene based on whether or not the line evaluation value has a characteristic of an object as a point light source. If the histogram shape determination unit and the point light source determination unit determine that the captured video is a night scene, the imaging apparatus determines that the scene captured by the image capturing unit is a night scene.
