CAPSULE ENDOSCOPE
First Claim
1. A capsule endoscope including an image pickup section for capturing an image of a region to be inspected to generate an image signal, a light source section for emitting illumination light every time said image pickup section captures said image, an image transmitter for transmitting said image signal to an external receiver via radio waves, a battery for supplying electric power to each of said image pickup section, said light source section and said image transmitter, and a capsule case for containing said image pickup section, said light source section, said image transmitter and said battery, said capsule endoscope comprising:
- an image capture controller having a power saving mode in which an image capturing rate per unit time is low and a normal capture mode in which said image capture rate per unit time is high, said image capture controller selecting one of said power saving mode and said normal capture mode to execute.

Abstract
A capsule endoscope is provided with an image pickup section having a CCD image sensor, a plurality of LEDs for emitting illumination light, a control circuit for controlling the image pickup section and the LEDs, a transmitting/receiving circuit for transmitting an image signal as a radio signal, and a battery for supplying electric power to each part of the capsule endoscope inside of a capsule case. When the capsule endoscope reaches a large intestine which is a lower digestive tract, the transmitting/receiving circuit receives an image capture initiation signal from an external transmitter provided outside of the body. The control circuit then activates the LEDs and the image pickup section to perform the image capturing at a predetermined interval.
