    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.

    Abstract: An image processing device is configured to obtain first-type image data and second-type image data generated as a result of taking images of same photographic subject from different directions, and generate a parallax image based on the first-type image data and the second-type image data. The image processing device includes a processor comprising hardware. The processor is configured to: set an image selection mode in which an image is selectable based on an image displayed in a display; superimpose a frame data onto image data to be displayed in the display when the image selection mode is set, the frame data representing a boundary area whose size is set based on an optical system that forms an image of the photographic subject; and obtain the first-type image data and the second-type image data corresponding to selected image when the image selection mode is set.
