Problems solved by technology

However, as mentioned above, the recognition processing for the computer-aided diagnosis (CAD) function requires huge calculation processing, and it is difficult to analyze all images without delay for the processing to realize high recognition accuracy
Therefore, in the image processing device 105 including the recognition processing circuit 153 as described above, even if a high-speed GP-GPU is used, the output image signal may be significantly delayed compared to the input endoscopic image signal.
[0013] Moreover, when this delay occurs, the image displayed on the monitor becomes slower relative to the movement of the endoscope, which may hinder the operation of the endoscope.
Also, performing computationally-intensive recognition processing to avoid delays can often lead to a reduction in recognition accuracy
