1. An image pickup device comprising:
- an image pickup unit which generates a plurality of continuously picked-up images by image pickup;
an object extracting unit which extracts a plurality of images each representing a moving object part from individual picked-up images generated by the image pickup unit;
a background image generating unit which generates a background image from the plurality of picked-up images generated by the image pickup unit;
a flash image generating unit which synthesizes the background image generated by the background image generating unit with the plurality of images each representing the object part extracted by the object extracting unit to generate a flash image;
a displacement detecting unit which detects a displacement between predetermined images among the plurality of picked-up images; and
an image smoothing unit which performs smoothing of an extracted image representing the moving object part by a process amount in accordance with the displacement detected by the displacement detecting unit;
wherein the image smoothing unit changes the process amount of smoothing based on a value acquired by multiplying the displacement detected by the displacement detecting unit by a coefficient.

Abstract
When a displacement between a reference frame of a plurality of images acquired by continuous image pickup and a target frame is less than a first threshold indicating that such a frame is not likely to be affected by occlusion, smoothing is performed on an object area through a morphological operation with a normal process amount. Conversely, when a displacement between the reference frame of the plurality of images acquired by continuous image pickup and a target frame is larger than or equal to the first threshold, smoothing is performed with the process amount of morphological operation being increased than a normal process amount.

7. A method of generating a flash image from a plurality of continuous images in which images of a moving object are picked up using a device which executes an image processing, the method comprising:
-
extracting a plurality of images each representing the moving object part from the plurality of continuous images; generating a background image from the plurality of continuous images; detecting a displacement between predetermined images among the plurality of continuous images; smoothing an extracted image by a process amount in accordance with the detected displacement; and synthesizing the generated background image with the plurality of extracted images each representing the object part to generate the flash image; wherein the process amount of the smoothing is changed based on a value acquired by multiplying the detected displacement by a coefficient.
