Abstract

A motion picture taking apparatus includes an image pickup device for taking plural images at a predetermined period, a memory for storing the plural images, a shake compensation amount detector for detecting a shake compensation amount for each of the plural images, an image synthesizer for compensating shakes among the plural images read out from the memory based on the shake compensation amount and for generating a synthesized image, and a signal processor for continuously outputting the synthesized image at the predetermined period.

Claims

1. A motion picture taking apparatus comprising:

an image pickup device for taking plural images at a predetermined period;

a memory for storing the plural images;

a shake compensation amount detector for detecting a shake compensation amount for each of the plural images;

an image synthesizer for compensating shakes among the plural images read out from said memory based on the shake compensation amount and for generating a synthesized image; and

a signal processor for continuously outputting the synthesized image at the predetermined period.

2. A motion picture taking apparatus according to claim 1, wherein said shake compensation amount detector includes:

a shake detector for detecting a shake amount of said motion picture taking apparatus;

a shake compensation amount operator for operating the shake compensation amount based on the shake amount that has been detected; and

a shake compensation amount memory for storing the shake compensation amount that has been operated while correlating the shake compensation amount with each of the plural images.

3. A motion picture taking apparatus according to claim 1, wherein said shake compensation amount detector includes a displacement amount operator for operating the shake compensation amount of each image based on a displacement amount of a feature point of each image.

4. A motion picture taking apparatus according to claim 1, wherein a charge accumulating period of said image pickup device is determined based on the number of images taken at the predetermined period.

5. A motion picture taking method comprising:

a taking step of taking plural images at a predetermined period;

a storing step of storing the plural images in a memory;

a shake compensation amount detecting step of detecting a shake compensation amount for each of the plural images;

an image synthesizing step of compensating shakes among the plural images read out from the memory based on the shake compensation amount and of generating a synthesized image; and

a signal processing step of continuously outputting the synthesized image at the predetermined period.
