Abstract: The present technology relates to an endoscope system in which resolution and an S/N ratio are adjusted to be well-balanced depending on an imaging condition, and further capable of changing a processing load depending on the imaging condition, a method for operating the endoscope system, and a program.From an image signal in a body cavity imaged by an endoscope apparatus, a low frequency image including a low frequency component and a high frequency image including a high frequency component are extracted. The low frequency image is reduced by a predetermined reduction ratio, and, after image quality improvement processing is performed, is enlarged by an enlargement ratio corresponding to the reduction ratio. At that time, based on condition information indicating an imaging state, when brightness at the time of imaging is sufficient and the high frequency component does not include noise components a lot, the low frequency image and the high frequency image are added to be output as an output image. In addition, based on the condition information, when the brightness at the time of imaging is not sufficient and the high frequency component includes the noise components a lot, only the low frequency image is output as the output image. The present technology can be applied to the endoscope system.

Abstract: An image processing part applies an image process by software to a surgical region image, and a display control part controls a display of the surgical region image to which the image process is applied. The image processing part produces a pre-update processed image acquired by applying the image process established before updating the software to the surgical region image and a post-update processed image acquired by applying the image process established after updating the software to the surgical region image, and the display control part controls a display of at least a portion of at least either one of the pre-update processed image or the post-update processed image. The present technique is applicable to a CCU of an endoscopic surgery system.

Abstract: The present disclosure relates to a control device and method, a program, and an endoscope system that are designed to be capable of shortening of the time before focusing.A target point distance calculation unit acquires an illumination intensity from an AE control unit, acquires a target point luminance value from a target point determination unit, and acquires an object reflectance from a reflectance holding unit. The target point distance calculation unit calculates (predicts) the distance to a target point, using the illumination intensity acquired from the AE control unit, the target point luminance value acquired from the target point determination unit, and the object reflectance acquired from the reflectance holding unit. Upon receipt of the target point distance from the target point distance calculation unit, the AF control unit searches for the focus position, using the received target point distance as the initial value. The present disclosure can be applied to an endoscope system to be used for surgeries, examinations, and the like, for example.
