Image processing system, imaging device, receiving device and image display device

An image processing system, comprising:

• an image generating means, having two observation modes of a first observation mode for capturing an image under illumination by a first light source and a second observation mode for capturing an image under illumination by a second light source different from the first light source, for generating an image to be displayed based on the image captured by selecting one of the observation modes;
• a brightness detecting means for detecting brightness of the image captured in one observation mode;
• and
• a controlling means for controlling an exposure operation or image processing in the other observation mode performed subsequent to an observation in the one observation mode based on the brightness of the image detected by the brightness detecting means.

An imaging device, comprising:

• an image generation unit that has two observation modes of a first observation mode for capturing an image under illumination by a first light source and a second observation mode for capturing an image under illumination by a second light source different from the first light source and generates an image to be displayed based on the image captured by selecting one of the observation modes;
• a brightness detection unit that detects brightness of the image captured in one observation mode;
• a control unit that controls an exposure operation or image processing in the other observation mode performed subsequent to an observation in the one observation mode based on the brightness of the image detected by the brightness detection unit;
• and
• a transmission unit that transmits the image generated by the image generation unit.

A receiving device, comprising:

• an image receiving unit that receives each of two images of an image captured under illumination by a first light source and an image captured under illumination by a second light source different from the first light source;
• a recording unit that records the image received by the image receiving unit in a predetermined recording region;
• a brightness detection unit that detects brightness of the image received by the image receiving unit;
• and
• a control unit that controls whether to allow the recording unit to record the image based on the brightness of the image detected by the brightness detection unit.

An image display device, comprising:

• an image processing unit that performs predetermined image processing on each of two images of an image captured under illumination by a first light source and an image captured under illumination by a second light source different from the first light source;
• a brightness detection unit that detects brightness of the image;
• a control unit that controls the predetermined image processing on the image by the image processing unit based on the brightness of the image detected by the brightness detection unit;
• and
• a display unit that displays at least one of the image and the image on which the predetermined image processing has been performed by the image processing unit.
