  • Publication number: 20200236271
    Abstract: The present technology relates to an image processing apparatus and method and an endoscopic system that permit reduction of uneven illumination distribution. An image processing apparatus includes a signal processing section that corrects uneven illumination of an image shot with a subject within a body of a patient to be operated on illuminated by a light source. The light source is arranged within the patient's body. The signal processing section corrects uneven illumination on the basis of a normally illuminated image and a low illuminated image. The normally illuminated image is shot with the subject within the body illuminated at a given illumination intensity. The low illuminated image is shot with the subject illuminated at a lower illumination intensity than the given illumination intensity.

  • Publication number: 20190298150
    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.

  • Publication number: 20190117052
    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.

  • Publication number: 20180263462
    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.
