Image-capturing device

A data generating device comprising:

• an image processor configured to acquire image-capturing data an image of which has been captured by receiving invisible band light;
• and
• a controller configured to generate invisible wavelength information defined based on a sensitivity characteristic, which is an output characteristic of an image sensor, to an object light flux wavelength for conversion of the image-capturing data into visible color space image data;
• wherein the image processor is further configured to relate the invisible wavelength information to the image-capturing data.

An image processing device comprising:

• an image processor;
• and
• a memory having computer-readable instructions stored thereon that, when executed by the image processor, perform operations including
• acquiring invisible image-capturing data including at least three types of image-capturing elements corresponding to respective wavelength bands in an invisible band passage of which has been allowed,
• acquiring observation information which is information about an observation target, and
• relating mutually different regions in a visible color space to the respective image-capturing elements based on the observation information to generate color image data.
