Abstract:
1. An electronic endoscope apparatus comprising: an electronic endoscope, wherein the processing apparatus includes: a connection unit capable of selectively connecting a plurality of machine types of electronic endoscopes in which a color space of color information to be obtained is different from each other; preprocessing unit configured to receive image data from the electronic endoscope and determine whether color space conversion is necessary to a second standard space; a standard space color converter configured to convert image data to the second standard color space when the preprocessing unit determines that the color space conversion is necessary; a plurality of replacement tables which are provided for the plurality of machine types of electronic endoscopes respectively, and each of which stores a correspondence between values representing colors which can be obtained by each of the electronic endoscopes by photographing an observation object and values representing the true colors of the observation object that have been obtained by measuring the color of each region of a human body with a measuring system during surgery; a machine type distinction mans which distinguishes the machine type of the electronic endoscope connected to the processing apparatus by obtaining information representing the machine type of the electronic endoscope from the electronic endoscope; a faithful-color—reproduced image production means which produces an image in which the true colors of the observation object are faithfully reproduced by performing a first phase of image processing that replaces the values of colors obtained by the electronic endoscope connected to the processing apparatus by suing the correspondence stored in the replacement table for the machine type distinguished by the machine type distinction means, a setting information storage means which can store setting information regulating the content of a second phase of image processing for each purpose of endoscopic examination, and an image processing means which refers to a set of setting information selected based on a selection signal input to the processing apparatus among the setting information stored in the setting information storage means, and which performs the second phase of image processing on the image produced by the faithful-color-reproduced image production means.
