    摘要: A noise reduction apparatus includes an input unit to input a captured image signal from a capturing unit. An acquisition unit acquires, according to a user operation, a temporal noise signal of the capturing unit based on the captured image signal. An estimation unit estimates an ideal image signal that has no noise, based on the captured image signal and the temporal noise signal. A removing unit removes a temporal frequency component higher than a predetermined threshold from each of the estimated ideal image signal and the acquired temporal noise signal. A generating unit generates a filter used for temporal noise reduction for a captured image signal in accordance with an added signal obtained by adding the ideal image signal from which the temporal frequency component has been removed by the removing unit and the noise signal from which the temporal frequency component has been removed by the removing unit.

    摘要: A video image signal that has only noise and does not include an object is acquired by a noise acquisition unit, a video image signal that is an image capture target is acquired by a video image characteristic acquisition unit, and each of the video image signals is multiplied by a frequency response characteristic of vision by a visual characteristic reflection unit to obtain a noise signal and a video image signal that does not include noise in which the frequency response characteristic of vision is reflected. A Wiener filter is generated with a filter designing unit based on the obtained signals, and is applied to a video image signal by a filtering unit.
