IMAGING APPARATUS, FLICKER DETECTION METHOD, AND FLICKER DETECTION PROGRAM
Provided are an imaging apparatus, a flicker detection method, and a flicker detection program that can accurately detect a flicker even in a case in which an image of a bright object is captured. A digital camera directs a MOS imaging element 5 to perform a plurality of imaging operations at an arbitrary frame rate and compares captured image signals which are read from the imaging element 5 for frame periods F1 and F2 based on the frame rate to detect whether a flicker has occurred. The end time of a signal reading period in the frame period F1 is before the end time of the frame period F1 and the end time of a signal reading period in the frame period F2 coincides with the end time of the frame period F2.
IMAGING CONTROL APPARATUS, IMAGING CONTROL METHOD, AND PROGRAM
In one example, an imaging apparatus includes an exposure controller that performs exposure control on the basis of information of a region of interest detected from a captured image by a region-of-interest detector. The exposure controller performs different exposure control for different cases, such as whether the region of interest is detected from the captured image. It obtains an exposure correction value on the basis of the region-of-interest exposure target value before a time of region-of-interest lost, and then performs exposure control with the exposure control value obtained by correcting the set region exposure target value with the exposure correction value, in a predetermined period in which the region of interest is not detected continuously from the time of the region-of-interest lost in which the region of interest is not detected from the captured image.

VEHICLE-MOUNTED CAMERA SYSTEM
In a vehicle-mounted camera system, an appropriate white balance correction processing according to a situation is executed to a long exposure time image and a short exposure time image shot in variously changing illumination environments. A vehicle-mounted camera system includes a vehicle-mounted camera that performs relatively long exposure time shooting and short exposure time shooting, a signal processing device (signal processing device) that executes a white balance correction processing for each of a long exposure time image and a short exposure time image, composes these images after the white balance correction processing, and generates a high dynamic range image, and a system control part (processing switch device) that obtains an illumination environment in which the vehicle is placed, and switches the white balance correction processing for the long exposure time image and the white balance correction processing for the short exposure time image according to the illumination environment.
