Description

Diagnostic device, diagnostic system, diagnostic method, and program Technical Field The present invention relates to a diagnostic device, a diagnostic system, a diagnostic method, and a program. Background Japanese patent No. 5162374 discloses an offset amount measuring device for an endoscope image. The device for measuring the amount of displacement of an endoscopic image described in japanese patent No. 5162374 includes a test chart on which a test pattern is drawn, a positioning mechanism, an image synthesizing mechanism, and an amount of displacement acquiring mechanism. The positioning mechanism positions either the tip of the insertion section of the electronic endoscope inserted into the body cavity or the test chart with respect to the other. The image synthesizing means synthesizes an endoscope image obtained by photographing a test chart with the electronic endoscope with a reference image, which is a mask image provided with an exposed portion that conceals an invalid region of the endoscope image and exposes only an effective region, after being positioned by the positioning means, and has a reference pattern at the exposed portion. The offset amount acquisition means acquires an offset amount of the test pattern with respect to the reference pattern from the synthesized image synthesized by the image synthesis means.
