Scanning endoscope system

A scanning endoscope system comprising:

• a scanning endoscope including:
• a light-guiding section that guides illumination light emitted from a light source;
• a driving section that enables the light-guiding section to swing such that an irradiation position of the illumination light emitted to an object through the light-guiding section draws a trajectory corresponding to a predetermined scanning pattern;
• and a light-receiving section that receives return light of the illumination light emitted to the object;
• a test chart device comprising a plane portion including a first region and a second region;
• a light detection section configured to generate a signal corresponding to an intensity of the return light received at the light-receiving section and output the generated signal;
• a pixel generation section configured to generate sampling pixels on the predetermined scanning pattern by sampling the signal outputted from the light detection section in a given sampling cycle;
• a first correction value calculation section configured to extract the first region from an image of the plane portion which includes the respective sampling pixels generated by the pixel generation section, and to further calculate a first correction value to be used for color balance adjustment of an image of the object based on a pixel value of each of the sampling pixels included in the first region;
• and
• a second correction value calculation section configured to extract the second region from the image of the plane portion which includes the respective sampling pixels generated by the pixel generation section, and to further calculate a second correction value to be used for pixel shift correction of the image of the object based on a pixel position of each of the sampling pixels included in the second region.
