Abstract
(EN)
[Problem] While alleviating the impact on the accuracy of an image which arises from a disparity correction which is intended for stereoscopic viewing, to allow achieving a desirable disparity which takes as a subject the working depth of a medical procedure. [Solution] Provided is a medical image processing device, comprising: a depth assessment unit which assesses the working depth of a medical procedure which is being imaged; a disparity assessment unit which, using a captured image which presents a field of view which is observed in the course of the procedure, assesses a disparity and generates disparity information; and a correction unit which corrects the disparity information, being dependent upon the working depth which is assessed by the depth assessment unit.

[Problème] tout en diminuant l’impact sur la précision d’une d’image qui est dû à une correction de disparité qui est destinée à la visualisation stéréoscopique, permettre d’obtenir une disparité souhaitable qui utilise en tant que sujet la profondeur de travail d’une procédure médicale. [Solution] La présente invention concerne un dispositif de traitement d’image médicale, comprenant : une unité d’évaluation de profondeur qui évalue la profondeur de travail d’une procédure médicale qui est imagée ; une unité d’évaluation de disparité qui, au moyen d’une image capturée qui présente un champ de vision qui est observé au cours de la procédure, évalue une disparité et génère des informations de disparité ; une unité de correction qui corrige les informations de disparité, en fonction de la profondeur de travail qui est évaluée par l’unité d’évaluation de profondeur.
