Title:
CONTROL SYSTEM, IMAGING DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2016040879
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a system and method that prevent a flicker from being generated even under an environment under which the flicker may be generated, to prevent information ranging from low brightness to high brightness from being lost.SOLUTION: A control system 100 includes: a photometric value calculation unit 101 that acquires, from an imaging device, a setting value set in the imaging device and calculates a photometric value on the basis of the acquired setting value; an exposure value calculation unit 102 for calculating an exposure value from the calculated photometric value; a setting value calculation unit 103 for calculating, as one of setting values, exposure time corresponding to the calculated exposure value; a detection unit 104 for detecting, on the basis of an image acquired by the imaging device in a prescribed period, the presence/absence of influence of flicker of light on the image; and a setting value adjustment unit 105 that sets exposure time for the imaging device to be predetermined time and at least performs adjustment of a set gradation correction value, when the presence of influence is detected and the calculated exposure time is equal to or shorter than predetermined time.SELECTED DRAWING: Figure 4
