Image-pickup apparatus
An image-pickup apparatus includes: an image-pickup device for converting light into an electric signal and outputting a first image data; a transmitting unit for successively transmitting the first image data to an apparatus in the exterior of the image-pickup apparatus; and a storage unit for storing a second image data extracted from the first image data per frame unit under a predetermined condition.
1. A capsule endoscope comprising:
an image pickup section configured to sequentially provide a color image data of an image pickup region;
an analyzing section configured to analyze the color image data from the image pickup section, select one of a plurality of image processions which are predetermined based on the analysis result, and perform image processing;
a transmitting section configured to transfer the color image data outside of a human body; and
a magnet for operating the capsule endoscope by externally applying a magnetic force;
a motion-detecting section provided in the analyzing section;
a motion-determination section provided in the motion-detecting section; and
an image-data-storage section provided in the analyzing section, wherein
the analyzing section detects a movement of the image pickup region from successive color images
the image-data-storage section stores the image data when the motion-determination section determines that the capsule endoscope is in “motionless” and a frame of the image data is not stored,
the motion-determination section determines that the capsule endoscope is in “motion” when the result value of the motion-determining is greater than a threshold value, and the capsule endoscope is in “motionless” when the result value of the motion-determining is smaller than the threshold value,
when a write address of the image-data-storage section reaches a maximum and the motion-determination section determines the capsule endoscope is in “motion”, the motion-determination section gives priority to outputting information from the image pickup section to outside of a human body, and
when a write address of the image-data-storage section reaches a maximum and the motion-determination section determines the capsule endoscope is in “motionless”, the motion-determination section gives priority to outputting information of the image-data-storage section to outside of the human body.
2. The capsule endoscope according to the claim 1 , further comprising:
an image data compressing section, wherein
the transmitting section transmits a compressed color image data by the image data compressing section outside of a human body.
3. The capsule endoscope according to the claim 1 , wherein
the plurality of image processions include a procession of storing a compressed color image which is compressed at lower than a specified data compression rate in the image data storage section.
4. The capsule endoscope according to claim 1 , wherein
the motion-determination section determines the result value according to a difference value of a motion vector extracted from within continuous images.
5. The capsule endoscope according to claim 1 , further comprising:
an image-compressing section provided in the analyzing section, wherein
the motion-determination section determines the result value according to a difference value of a coded-amount of compressed continuous images.
6. The capsule endoscope according to claim 1 , wherein:
the motion-determination section adds information indicative of whether the frame of the image data is stored in the image-data-storage section to the image data from the image-pickup section and the motion-determination section outputs the information to outside of a human body.
