Abstract: A developing cartridge includes: a casing configured to accommodate therein toner; a developing roller; a supply roller configured to supply the toner to the developing roller; a layer thickness regulation blade in contact with a circumferential surface of the developing roller; a developing electrode electrically connected to the developing roller; and a supply electrode electrically connected to the supply roller and the layer thickness regulation blade. The supply electrode includes: an electrode member electrically connected to a rotation shaft of the supply roller and movable in a direction perpendicular to the rotation shaft; and a connection member in contact with and electrically connecting the electrode member and the layer thickness regulation blade. The electrode member is movable relative to the connection member in the direction perpendicular to the rotation shaft in a state where the electrode member is in contact with the connection member.

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.

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).
