Abstract
An imaging device including an image sensor, includes an image obtaining control unit that obtains plural continuous images of an object taken by the image sensor; a size determining unit that determines an image size of reduced images based on photographing information of at least one of the images, and generates reduced images from the images obtained by the image obtaining control unit based on the determined image size; a motion vector detection unit that detects a motion vector of the reduced images; and an image synthesis unit that synthesizes the images obtained by the image obtaining control unit based on the motion vector detected by the motion vector detection unit to obtain a synthesized image.
Claims19
An imaging device including an image sensor, comprising:
- an image obtaining control unit that obtains plural continuous images of an object taken by the image sensor;
- a size determining unit that determines a reduction ratio for reduced images with respect to the images taken by the image sensor based on photographing information of at least one of the images taken by the image sensor, and generates the reduced images by reduction of the images taken by the image sensor and obtained by the image obtaining control unit based on the determined reduction ratio;
- a motion vector detection unit that detects a motion vector of the reduced images;
- and
- an image synthesis unit that synthesizes the images obtained by the image obtaining control unit based on the motion vector detected by the motion vector detection unit to obtain a synthesized image.
A method of obtaining an image by an image sensor, comprising:
- obtaining plural continuous images of an object taken by the image sensor;
- determining a reduction ratio for reduced images with respect to the images taken by the image sensor based on photographing information of at least one of the images taken by the image sensor;
- generating the reduced images by reduction of the obtained images taken by the image sensor based on the determined reduction ratio;
- detecting a motion vector of the reduced images;
- and
- synthesizing the obtained images based on the detected motion vector to obtain a synthesized image.
A non-transitory computer-readable recording medium having recorded thereon a program that causes a computer to execute a method of obtaining an image by an image sensor comprising:
- obtaining plural continuous images of an object taken by the image sensor;
- determining a reduction ratio for reduced images with respect to the images taken by the image sensor based on photographing information of at least one of the images taken by the image sensor;
- generating the reduced images by reduction of the obtained images taken by the image sensor based on the determined reduction ratio;
- detecting a motion vector of the reduced images;
- and
- synthesizing the obtained images based on the detected motion vector to obtain a synthesized image.
