Abstract: A flexible printed circuit board according to an embodiment includes a base film and a first wire. The base film has a first surface. The first wire is disposed on the first surface. The first wire has a first layer and a second layer. The first layer is disposed on the first surface directly or indirectly. The second layer covers the first layer. In the first surface, a first groove is formed next to the first layer in a plan view. The second layer on a side surface of the first layer exists on a bottom surface and a side surface of the first groove.

Abstract: An image processing apparatus (13) according to one form of the present disclosure includes: an image input unit (13b) that receives an operative field image for an eye of a patient; an eyeball tracking unit (13e) that tracks an eyeball in the operative field image; and a display image generation unit (13f) that sets a plurality of regions having different display modes for the operative field image and generates a display image in which an annular or radial boundary in the plurality of regions indicates a specific position or a specific size with respect to the eye. The display image generation unit (13f) changes a position or a size of the boundary on the basis of a tracking result of the eyeball and generates the display image.

Abstract: An image processing device (13) according to one aspect of the present disclosure includes: an image input unit (13a) that receives a surgical field image with respect to a patient's eye; an eyeball tracking unit (13b) as an example of a part detection unit that detects a specific part of the eye in the surgical field image; and a display image generation unit (13c) that generates a display image including a first position indicator indicating a position a predetermined distance away in a specific direction from the specific part detected by the eyeball tracking unit (13b).

Abstract: A medical image processing device includes: image acquisition unit configured to acquire image information obtained by imaging with a medical observation device; and superimposed image generation circuitry configured to generate a superimposed image in which a pattern image having first images with a specific shape arranged in parallel in a specific pattern and a captured image based on the image information are superimposed on each other.
