Claims18
An endoscopic apparatus comprising:
- an endoscope that picks up an image of the inside of a tubular cavity;
- a light source device that supplies illumination light to the endoscope and has light source identification information storage unit for storing light source identification information;
- an image processing device that performs signal processing on image pickup signals from the endoscope and creates an endoscopic image,
- first white balance data storage unit for storing, for each of the light source identification information, white balance data to be used for white balance processing in the image processing device at least in association with the light source identification information;
- second white balance data storage unit for storing white balance data to be used for white balance processing in the image processing device;
- light source information extracting unit for extracting light source identification information of the light source device;
- white balance data searching unit for searching white balance data associated with the light source identification information through the first white balance data storage unit based on the light source identification information of the light source device, which is extracted by the light source information extracting unit;
- and
- white balance data extracting unit for extracting white balance data stored in the second white balance data storage unit based on the result of the search by the white balance data searching unit.
