Abstract

An imaging apparatus and an imaging method are provided. The imaging apparatus includes an imager configured to output image data for a subject, a motion detector configured to detect motion of the imaging apparatus, and a controller configured to control the imager to suspend output of the image data in response to the motion detector detecting the motion.

First claim

What is claimed is:

1. An imaging apparatus comprising:
an imager configured to output image data of a plurality of pixels of an image frame for a subject sequentially from a first pixel in a first row and a first column of the image frame to a last pixel in a last row and a last column of the image frame;
a motion detector configured to detect motion of the imaging apparatus; and
a controller configured to control the imager to:
suspend output of remaining image data of a remaining pixel of the image frame in response to the detected motion being greater than or equal to a value; and
restart output of the image data of the plurality of pixels sequentially from the first pixel in response to the detected motion being less than the value after the output of the remaining image data is suspended.

2. The imaging apparatus as claimed in claim 1 , wherein the imager comprises a complementary metal oxide semiconductor sensor.

3. The imaging apparatus as claimed in claim 1 , wherein the motion detector comprises at least one among an acceleration sensor, an angular velocity sensor, and a gyroscope.

4. The imaging apparatus as claimed in claim 1 , wherein the motion detector is further configured to continuously detect the motion.

5. The imaging apparatus as claimed in claim 1 , further comprising an image processor configured to process the output image frame.

6. The imaging apparatus as claimed in claim 5 , wherein the controller is further configured to control the image processor to generate an image, based on the output image frame, in response to the imager outputting the image frame.

7. The imaging apparatus as claimed in claim 5 , wherein the controller is further configured to set ranks for a plurality of images, based on the detected motion corresponding to the output image frame, in response to the imager outputting the image frame.

8. The imaging apparatus as claimed in claim 7 , wherein the controller is further configured to control the image processor to generate an image, based on the set ranks.

9. The imaging apparatus as claimed in claim 5 , wherein the controller is further configured to control the image processor to generate an image, based on the output image frame, in response to the imager outputting a number of image frames.

10. The imaging apparatus as claimed in claim 1 , wherein the controller is further configured to set ranks for a plurality of images for which each of respective motions of the imaging apparatus is less than the value, based on the detected motion corresponding to the output image frame, in response to the imager outputting the image frame, the plurality of images comprising the output image frame, and the detected motion corresponding to the output image frame being less than the value,
a first image corresponding to a lowest motion of the imaging apparatus among the plurality of images is set to have a highest ranking among the plurality of images,
a second image corresponding to a middle motion of the imaging apparatus among the plurality of image is set to have a middle ranking among the plurality images, and
a third image corresponding to a highest motion of the imaging apparatus among the plurality of images is set to have a lowest ranking among the plurality of images.

11. An imaging apparatus comprising
an imager configured to output image data of a plurality of pixels of an image frame for a subject sequentially from a first pixel in a first row and a first column of the image frame to a last pixel in a last row and a last column of the image frame;
a motion detector configured to detect motion of the imaging apparatus; and
a controller configured to control the imager to:
suspend output of remaining image data of a remaining pixel of the image frame, and exclude the output image data from image synthesis, in response to the detected motion being greater than or equal to a value; and
restart output of the image data of the plurality of pixels sequentially from the first pixel in response to the detected motion being less than the value after the output of the remaining image data is suspended.

12. The imaging apparatus as claimed in claim 11 , wherein the imager comprises a charge-coupled device sensor.

13. The imaging apparatus as claimed in claim 11 , wherein the motion detector comprises at least one among an acceleration sensor, an angular velocity sensor, and a gyroscope.

14. The imaging apparatus as claimed in claim 11 , further comprising an imaging processor configured to process the output image frame.

15. The imaging apparatus as claimed in claim 14 , wherein the controller is further configured to control the image processor to generate an image, based on the output image frame, in response to the imager outputting the image frame.

16. The imaging apparatus as claimed in claim 14 , wherein the controller is further configured to set ranks for a plurality of images, based on the detected motion corresponding to the output image frame, in response to the imager outputting the image frame.

17. The imaging apparatus as claimed in claim 16 , wherein the controller is further configured to control the image processor to generate an image, based on the set ranks.

18. The imaging apparatus as claimed in claim 14 , wherein the controller is further configured to control the image processor to generate an image, based on the output image frame, in response to the imager outputting a number of image frames.

19. The imaging apparatus as claimed in claim 11 , wherein the controller is further configured to determine a number of motion data to be detected by the motion detector, based on imaging environment conditions.

20. An imaging method of an imaging apparatus, the imaging method comprising:
outputting image data of a plurality of pixels of an image frame for a subject sequentially from a first pixel in a first row and a first column of the image frame to a last pixel in a last row and a last column of the image frame;

suspending output of remaining image data of a remaining pixel of the image frame in response to the detected motion being greater than or equal to a value; and
restarting output of the image data of the plurality of pixels sequentially from the first pixel in response to the detected motion being less than the value after the output of the remaining image data is suspended.

21. The imaging method of claim 20 , further comprising:
determining whether a number of image frames that are output is greater than or equal to another value; and
processing the output image frames in response to the determining that the number of the image frames is greater than or equal to the other value, to generate an image.

22. An imaging method of an imaging apparatus, the imaging method comprising:
outputting image data of a plurality of pixels of an image frame for a subject sequentially from a first pixel in a first row and a first column of the image frame to a last pixel in a last row and a last column of the image frame;
