The second image generation unit generates a second image (bright/dark region discrimination image or the like), using at least one image having a different corresponding wavelength from that of the image used for the generation of the first image. The region discrimination unit discriminates the regions in the observation target, using the second image.

An image processing unit includes a shake amount calculation section and a static image-storage control section, and the shake amount calculation section includes a shake amount-calculation processing section and an algorithm switching section. The algorithm switching section applies an algorithm varying for each image, and selects images of which the shake amounts calculated by the shake amount-calculation processing section are small. A first image and a second image, which are selected as the images of which the shake amounts are small, are stored in a static image-storage unit. A display control unit displays static images for storage.

An endoscope includes a light source coupled to emit light, and a lens disposed proximate to a distal tip of the endoscope tube and structured to absorb at least some of the light. A controller is coupled to the light source, and the controller includes logic that when executed by the controller causes the endoscope to perform operations, including adjusting an emission profile of the light source to heat the lens with the light, and heating the lens mitigates formation of fog on the lens.

A medical image processing apparatus includes: image signal acquiring circuitry configured to acquire: a first image signal generated by capturing light of a first wavelength band with an image sensor; and a second image signal generated by capturing light of a second wavelength band different from the first wavelength band with the image sensor, the first image signal and the second image signal being not subjected to the demosaic processing, and the image sensor including a color filter in which filter groups having spectroscopic properties different from each other are arranged in a specific form; a first signal path including a demosaic processor configured to execute the demosaic processing to the first image signal; and a second signal path diverged from the first signal path on a path former part from the demosaic processor, in which the demosaic processing is not executed to the second image signal.

Pulsed hyperspectral, fluorescence, and laser mapping imaging without input clock or data transmission clock is disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a plurality of bidirectional data pads and a controller in communication with the image sensor. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of: electromagnetic radiation having a wavelength from about 513 nm to about 545 nm, from about 565 nm to about 585 nm, from about 900 nm to about 1000 nm, an excitation wavelength of electromagnetic radiation that causes a reagent to fluoresce, or a laser mapping pattern.

The disclosed technology relates to closed-loop medical imaging for a medical environment. Various embodiments provide for a surgical camera, such as an endoscopic camera, comprising one or more image sensors. The image sensors may be configured to capture multispectral image data including one or more images of biological tissue (e.g., surfaces), and may be specifically configured to capture imagery within a surgical environment. For some embodiments, different biological tissues may be visible when illuminated by different wavelengths of a multispectral light source. The wavelength setting for the multispectral light source may be determined based upon a first wavelength setting associated with a first set of multispectral image data and a second wavelength setting associated with a second set of multispectral image data.
