Document Type and Number:
Japanese Patent JP5846277
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of calculating the flicker frequency of a light source without complicating arithmetic processing.SOLUTION: An imaging apparatus includes an imaging device, an acquisition part, an average value calculation part, and a frequency calculation part. The imaging device is the XY-address scan type imaging device having an imaging region where multiple pixels are two-dimensionally arrayed. The acquisition part indicates the imaging device to perform thinning-out reading by line unit, so as to sequentially acquire an image signal of a subregion read by thinning-out from the imaging region. The average value calculation part calculates the average values of brightness of the image signal by each frame. The frequency calculation part calculates the frequency of a light source, based on the temporal change of the average values which are calculated by each frame.
