CAMERA CONTROL APPARATUS AND METHOD OF CONTROLLING A CAMERA
First Claim
1. A camera control apparatus which controls an exposure time upon capturing a moving image by a camera mounted on a movable body, comprising:
- a memory for storing frame information of the moving image captured by the camera;
an image capturing unit for capturing the frame information from the camera and storing the frame information 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 frame information stored in the memory; and
a updating unit for selecting a shorter time between the first candidate and the second candidate, and for updating the exposure time to the selected candidate.

Abstract
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.

8. A camera control method for controlling a camera mounted on a movable body, comprising:
-
storing frame information of the moving image captured by the camera; capturing the frame information from the camera and storing the frame information into the memory; generating the first candidate of the exposure time on the basis of a speed of the movable body; generating a second candidate of the exposure time on the basis of the frame information stored in the memory; selecting a shorter time between the first candidate; and updating the exposure time to the selected candidate.

9. A camera control apparatus including a counter and a communicator, the counter counting clock signals, the communicator setting the count value of the counter to the same value as the count value of other devices and communicating on the basis of count value of the counter, the camera control apparatus comprising:
-
a first register for holding a count value upon being outputted a moving image beginning signal; a second register for holding a count value corresponds to taking moving image intervals; an accumulator for adding the count value in the first register and the count value in the second register; and an output unit for outputting the moving image beginning signal to the camera when the added value at accumulator is same as the count value of the counter.
