Processor for electronic endoscope, videoscope, and electronic endoscope apparatus

An electronic endoscope apparatus, comprising a processor and a videoscope connected with the processor,

• wherein the videoscope is configured to generate a color-adjusted picture signal from a color image signal for an image of an observed object through color adjustment using first color adjustment data and to transmit the generated color-adjusted picture signal to the processor,
• wherein the processor comprises:
• a light source configured to emit light for illuminating the observed object;
• a determiner configured to determine whether or not the first color adjustment data used by the videoscope is adapted to the light source;
• a color conversion data acquirer configured to acquire color conversion data compatible with the first color adjustment data when the determiner determines that the first color adjustment data is not compatible with the light source;
• and
• a color converter configured to:
• receive the color-adjusted picture signal generated through the color adjustment using the first color adjustment data;
• generate a video signal from the received color-adjusted picture signal by performing color conversion based on the color conversion data acquired by the color conversion data acquirer, the color conversion re-adjusting a color tone of the color-adjusted picture signal generated using the first color adjustment data not compatible with the light source, so as to generate the video signal with the re-adjusted color tone;
• and
• transmit the generated video signal to a monitor.

• and a color converter configured to:
• receive the color-adjusted picture signal generated through the color adjustment using the first color adjustment data;
• generate a video signal from the received color-adjusted picture signal by performing color conversion for the picture signal transmitted by the videoscope based on the color conversion data acquired by the color conversion data acquirer, the color conversion re-adjusting a color tone of the color-adjusted picture signal generated using the first color adjustment data not compatible with the light source, so as to generate the video signal with the re-adjusted color tone;
• and
• transmit the generated video signal to a monitor;
• wherein the videoscope comprises:
• an image sensor configured to generate a color image signal for the image of the observed object formed under illumination with the light supplied by the light source of the processor;
• a color adjustment data acquirer configured to acquire color adjustment data adapted to the light source from the processor;
• a color adjustment data storage configured to store the color adjustment data acquired by the color adjustment data acquirer;
• and
• a color adjuster configured to convert the color image signal generated by the image sensor into a color-adjusted picture signal through color adjustment using the color adjustment data stored by the color adjustment data storage.
