Title:
IMAGING DEVICE, FLICKER DETECTION METHOD, AND FLICKER DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/139847
Kind Code:
A1
Abstract:
Provided are an imaging device, a flicker detection method, and a flicker detection program, whereby flicker from light sources having different frequencies can be differentiated and detected by simple processing and without changing exposure time. A digital camera detects the presence of 50 Hz flicker and 60 Hz flicker, on the basis of: a captured image signal (1) obtained by capturing images at a first frame rate; a captured image signal (2) obtained by capturing images at a second frame rate following the first image capture; and a captured image signal (3) obtained by capturing images at the first frame rate following the second image capture. The first frame rate is a value obtained by dividing 120 Hz by a natural number. The second frame rate is a value other than the value obtained by dividing 120 Hz by a natural number.
