Endoscope image pick-up apparatus
First Claim
1. An endoscope image pick-up apparatus comprising:
- an image pick-up unit for insertion into the body for capturing an image;
an extra-corporeal unit arranged outside the body, the extra-corporeal unit receiving the image captured by the image pick-up unit by radio;
a data transmitting device provided in the image pick-up unit for transmitting the image obtained by the image pick-up device to the extra-corporeal unit at a plurality of transmitting ratios;
a characteristic amount detecting device provided in the image pick-up unit for detecting a first amount of characteristics and a second amount of characteristics different from the first amount of characteristics from the image obtained by the image pick-up unit, the first amount of characteristics detected by the characteristic amount detecting device being a number of pixels having a specific color; and
a determining device provided in the image pick-up unit for determining a validity of the image according to the characteristic amount detected by the characteristic amount detecting device, the determining device having a first determining device for determining the validity of the image based on the number of pixels having a specific color detected as the first amount of characteristics, and a second determining device for determining the validity of the image based on the second amount of characteristics, the second amount of characteristics being selected from optical characteristics other than color-specific characteristics, the data transmitting device controls the data transmitting ratio in accordance with the determining result of the determining device.

Abstract
An image pick-up unit inserted in the body picks up an image of the body, and transmits by radio the image to an extra-corporeal unit which is arranged outside the body. The image pick-up unit includes an image pick-up portion capturing an image, a data transmitting portion for transmitting the image obtained by the image pick-up portion to the extra-corporeal unit at a plurality of transmitting ratios, a characteristic amount detecting portion for detecting a predetermined amount of characteristics based on the image, and a determining portion for determining a valid image based on an output from the characteristic amount detecting portion. The data transmitting portion controls the data transmitting ratio in accordance with the determining result of the determining portion.
