Image processing device, imaging device, and image processing method

An imaging device, comprising:

• an imaging apparatus configured to sequentially acquire a plurality of images captured in chronological order;
• and
• circuitry configured to:
• detect whether a light source has blinked during an exposure period of a detection target image among the plurality of images;
• output a detection result based on the detection that the light source has blinked;
• generate a synthesis ratio based on the detection result;
• determine whether a brightness change is present between the plurality of images;
• output a determination result based on the determination that the brightness change is present between the plurality of images;
• modulate the synthesis ratio based on the determination result;
• correct the modulated synthesis ratio so as to make a percentage of the detection target image lower than a percentage of an image other than the detection target image among the plurality of images;
• and
• synthesize the plurality of images at the corrected synthesis ratio.
