Image processing apparatus

An image processing apparatus that performs signal processing on an image signal captured by an endoscope connected thereto, the image processing apparatus comprising:

• an image signal processing circuit that is formed by use of a rewritable logic circuit, the image signal processing circuit being configured to perform signal processing on the image signal according to a type of the endoscope;
• a display image processing circuit that is formed by use of a rewritable logic circuit, the display image processing circuit being configured to generate, based on a processed signal obtained by the signal processing of the image signal processing circuit, a display image signal corresponding to a display mode of a display apparatus;
• and
• a control circuit configured to
• control the display image processing circuit to perform configuration when the image processing apparatus is started up,
• control the image signal processing circuit to perform configuration according to a type of the endoscope connected to the image processing apparatus,
• when replacement of the endoscope with another endoscope is detected after the configurations are performed by the image signal processing circuit and the display image processing circuit, control the image signal processing circuit to perform reconfiguration according to a type of said another endoscope, wherein the display image processing circuit does not perform reconfiguration when the replacement of the endoscope with said another endoscope is detected, and
• control the display apparatus to display a display image based on the display image signal generated by the display image processing circuit.
