<p>PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of performing satisfactory imaging in the night without lights.SOLUTION: The imaging apparatus includes: a plurality of LED projectors which are adjusted to optical axes in the same direction in a time division control manner; a zoom lens; and a CPU for controlling the time division of the LED projectors, a zoom and an iris of the zoom lens. The imaging apparatus is configured to image a gray scale chart to adjust detection video balance. The CPU controls the time division of the LED projectors, the zoom and the iris of the zoom lens and performs adjustment in such a manner that a G signal level of an intermediate gray color in upper, lower, right and left portions in a center of the gray scale chart and a G signal level of an intermediate gray color in portions around the gray scale chart become predetermined signal levels, respectively, and adjusts the detection video balance.</p> |
