There are provided an endoscopic diagnosis apparatus, image processing method, program, and a recording medium that enable easy measurement of the size of a lesion portion or the like based on an endoscopic image captured through a normal operation without a special operation. A region detecting unit detects, from an endoscopic image, a region of an artificial object or the like that is in contact with a subject. An imaging size calculating unit calculates, in number of pixels, an imaging size in the endoscopic image of the region of the artificial object or the like that is in contact with the subject. A pixel size calculating unit calculates an actual size corresponding to one pixel. A scale generating unit generates scales indicating an actual size of the subject in the endoscopic image. A control unit performs control to combine the endoscopic image and the scales and to display.
