An image generating device for an endoscope, the device provided with: an image processing unit that receives imaging signals as input from a camera head and that generates, on the basis of the inputted imaging signals, an output captured image that can be displayed on a display unit a zoom information acquiring unit that acquires zoom magnification information that indicates the size of a subject image with respect to the output captured image a deviation amount calculating unit that calculates the deviation amount between the center of the output captured image and the center of the subject image a deviation correction amount calculating unit that calculates a deviation correction amount on the basis of the ratio between a first zoom magnification from the time of deviation amount calculation and a set second zoom magnification, as well as on the basis of the deviation amount calculated by the deviation amount calculating unit, the deviation correction amount being for correcting the deviation between the center of the output captured image and the center of the subject image and a position correcting unit that corrects the output captured image on the basis of the deviation correction amount such that the center of the subject image coincides with the center of the output captured image, and then outputs the output captured image to the display unit.Linvention concerne un dispositif de génération dimages pour endoscope, ledit dispositif comportant : une unité de traitement dimages qui reçoit des signaux dimagerie en entrée émis par une tête de caméra et qui génère, daprès les signaux dimagerie entrés, une image capturée de sortie qui peut être affichée sur une unité daffichage une unité dacquisition de données de zoom qui acquiert des données dagrandissement indiquant la taille dune image objet par rapport à limage capturée de sortie une unité de calcul décart qui calcule lécart entre le centre de limage capturée de sortie et le centre de limage objet une unit
