Abstract: The present disclosure relates to a surgical system, a surgical control method, and a program enabling image processing with high accuracy in a case of changing an amount of light applied to a subject of a surgical imaging device. A light source control unit changes the light amount of the light applied to the subject imaged by an endoscope from a default value to a high light amount larger than the default value. An image processing unit performs image processing using a high light amount image which is an intraoperative image captured by the endoscope in a state in which the light amount is the high light amount. The image processing unit adjusts brightness of the high light amount image on the basis of the high light amount to generate a display image and displays the display image on a display device. The present disclosure is applicable to, for example, an endoscopic surgical system and the like.

Abstract: The present technology relates to an image processing device, an image processing method, an endoscope system, and a program that enable motion detection with higher accuracy. The endoscope system includes: a light source capable of performing a pulsed-light emission; a light-source control unit that controls the light source such that the light source performs the pulsed-light emission a plurality of times in an exposure time period of each captured image; an imaging unit that takes the captured images; and a motion detection unit that detects a motion of a photographic subject in the captured images. The present technology is applicable to the endoscope system.

Abstract: The present disclosure relates to an image processing apparatus, an image processing method, a program, and an endoscope system capable of obtaining an image with high color discrimination. A histogram generation unit generates histograms of pixel values for an input image regarding luminance Y, saturation S, and hue H. A histogram correction unit subtracts components of the saturation, the luminance, and the hue of a portion determined to be a foreign object by a foreign object detection unit from the histograms regarding the saturation, the luminance, and the hue generated by the histogram generation unit and then weights by a value of a standard histogram. The present disclosure may be applied to the endoscope system which performs color conversion on an image input from a camera head through a scope, for example.

Abstract: In a medical system (1), speckle contrast calculation means (1313, 1314) calculates a first speckle contrast value for each pixel based on a first speckle image at a first exposure time and/or a second speckle contrast value for each pixel based on a second speckle image at a second exposure time shorter than the first exposure time. In addition, speckle image generation means (1315) generates a speckle contrast image on the basis of the first speckle contrast value and/or the second speckle contrast value depending on a detection result of motion of an image capturing target by motion detection means (1312).

Abstract: [Object] To propose a control apparatus, a control system and a control method which are capable of appropriately determining an irradiation period in a scene in which light is radiated at the same time as imaging.[Solution] A control apparatus including: a light source control unit configured to determine a period in accordance with a period between an exposure start timing of a first line in an image pickup element and an exposure end timing of a second line in the image pickup element as an irradiation period during which a light source unit is caused to radiate light. The second line is a line in which start of exposure in one frame is earlier than in the first line.

Abstract: Provided is an image processing device including: an image processing unit that generates image data for output from a captured image of an inside of a body cavity of a patient photographed by an endoscope. The image processing unit generates the image data in a manner that, when a lens barrel of the endoscope is moved in an optical axis direction of an objective lens during photographing, a display range in the captured image that is a range expressed in a display image displayed on a display device does not change, during the movement and after the movement, from a display range before the movement.
