A camera control apparatus which controls an exposure time of a camera that takes a moving image, the camera includes a memory for storing the moving image taken by the camera, an image capturing unit for capturing the moving image from the camera and storing the moving image into the memory, a first candidate generator for generating the first candidate of the exposure time on the basis of a speed of the movable body, a second candidate generator for generating a second candidate of the exposure time on the basis of the moving image stored in the memory, and, a setting unit for selecting a shorter time between the first candidate and the second candidate, and for setting the selected candidate as the exposure time.
