Patent ID: 8553075

Claim:
An endoscope apparatus, comprising: a scope for obtaining an endoscope image by imaging a subject; an edge extractor configured to extract an edge component of the endoscope image obtained by the scope; a complexity degree detector configured to detect a complexity degree of the edge component extracted by the edge extractor; an imaged state determination unit configured to determine whether the endoscope image is an image obtained through near view imaging or distant view imaging of the subject according to the complexity degree detected by the complexity degree detector; and a condition changing unit configured to change an imaging condition according to the near view imaging or distant view imaging determined by the imaged state determination unit, wherein the imaged state determination unit determines the endoscope image to be an image obtained by the near view imaging if the complexity degree is not less than a set threshold value and to be an image obtained by the distant view imaging if the complexity degree is less than the set threshold value.
