Endoscopic device and operating method thereof

An endoscopic device including an endoscopic scope which irradiates illumination light from a tip of an insertion unit which is inserted in a subject and outputs a frame image signal which is captured by an image capturing unit mounted in the tip of the insertion unit and a processor device which is connected to the endoscopic scope and includes an image processing unit which performs image processing on the frame image signal, the device comprising:

• a light source unit configured to repeat for every frame period, an operation of emitting the illumination light during a front period obtained by dividing a frame period of the frame image signal by two and turning off the illumination light during a back period of the frame period;
• a buffer memory mounted in the endoscopic scope and configured to store image information of the frame image signal output from the image capturing unit;
• and
• an information transmitting unit configured to read out the image information of the frame image signal from the buffer memory and transmit the image information to the image processing unit,
• wherein the image capturing unit considers the front period of the frame period as an exposure period and reads out signals of the exposed accumulated charges within the back period to output the signal to the buffer memory as the image information of the frame image signal, and
• the information transmitting unit reads out the image information of the frame image signal from the buffer memory within the frame period.
