Abstract

An image capturing apparatus and a method of operating the same are provided. The image capturing apparatus includes: an imaging device configured to obtain, based on a previously set exposure condition, an imaging signal that corresponds to at least one frame; a flicker information determining circuitry configured to determine flicker information of a light source using the imaging signal that corresponds to the at least one frame; and a controller configured to control, based on the flicker information of the light source, an exposure start time of the imaging device in order to take into account flicker occurrence due to the light source.

Description

[0001] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2016-0004409 filed with the Korean Intellectual Property Office on Jan. 13, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to image capture devices and methods of operating the image capture devices. Background technique [0003] In addition to the characteristics of the objects in the scene from the perspective of the image capture device, the scene may be captured in proportion to the brightness of an external light source, such as a solar lamp or lighting. The brightness of solar lights or light emitting diode (LED) lighting changes little during a certain period of time within a few seconds. However, the brightness of an incandescent lamp, a fluorescent lamp, etc. using alternating current (AC) power changes at a rate proportional to the frequency of the alternating curre...
