Abstract
An endoscopic image processing apparatus includes a memory configured to store a threshold THn to determine a dark region in the near-point image inputted, a brightness correction circuit configured to perform brightness correction on the near-point image based on the threshold THn depending on timing of acquiring the near-point image and perform second brightness correction on the far-point image based on a threshold THf on the far-point image, and a light distribution state determination circuit configured to determine whether a light distribution state of a live image from an endoscope is a light distribution state of the near-point image. The brightness correction circuit, in the timing of acquiring the near-point image, performs the first brightness correction when the light distribution state determination circuit determines that the light distribution state of the live image is the light distribution state of the near-point image.
