Abstract

Disclosed is an image synthesizer including an image frames memory which memorizes a plurality of image frames which are produced by continuously taking pictures of a subject, an image synthesizer which synthesizes a plurality of image frames to a summation image, an image brightness adjuster which adjusts brightness of the summation image by synthesizing the image frames with the image synthesizer, and a display which displays the summation image which is being synthesized by the image synthesizing means in the image brightness adjusting processing.

Claims

1. An image synthesizing apparatus comprising:

an image frames memory which memories a plurality of image frames which is produced by continuously taking pictures of a subject;

an image synthesizer which synthesizes a plurality of image frames to a summation image;

an image brightness adjuster which adjusts brightness of the summation image by synthesizing the image frames with the image synthesizer; and

a display which displays the summation image which is being synthesized by the image synthesizing means in the image brightness adjusting processing.

2. The image pickup apparatus according to claim 1, further comprising:

a noise reducing section which further synthesizes the image frames onto the synthesized image produced by the image brightness adjusting processing by the image synthesizing section so as to reduce noise of the synthesized image.

3. An image pickup apparatus comprising:

a picture-taking device which executes continuously taking pictures of a subject to output a plurality of image frames;

an image frames memory which memories a plurality of image frames which is produced by the picture-taking device;

an image synthesizer which synthesizes a plurality of image frames to a summation image;

an image brightness adjuster which adjusts brightness of the summation image by synthesizing the image frames with the image synthesizer; and

a display which displays the summation image which is being synthesized by the image synthesizing means in the image brightness adjusting processing.

4. The image pickup apparatus according to claim 3, further comprising:

a picture-taking operation input section to receive an input of a picture-taking command of the subject by the picture-taking device, wherein

the image brightness adjuster executes the image brightness adjusting processing while the picture-taking operation input section receives the picture-taking command from an operator.
