    Abstract: An EDOF signal processing unit performs EDOF signal processing as restoration processing on a special light image acquired by imaging an observation target irradiated with special light, and a setting unit sets a restoration degree of the EDOF signal processing for the EDOF signal processing unit. Then, a parameter for the restoration degree in the EDOF signal processing on the special light image is set so as to make the restoration degree in the EDOF signal processing on the special light image lower than a restoration degree in EDOF signal processing as restoration processing on a normal light image acquired by imaging the observation target irradiated with normal light. The present technology may be applied to, for example, a medical image processing system that performs special light observation.

    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.

  • Patent number: 10799087
    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.
