Abstract
An information processing apparatus including a determination unit configured to acquire an image including a target pixel as a pixel of a local positive peak signal and captured by a photon-counting image sensor, an interpolation unit configured to interpolate an interpolation signal to a peripheral pixel as a pixel around the target pixel of the image, and a reduction unit configured to reduce noise of the image in which the interpolation signal has been interpolated. The local positive peak signal spreads over a plurality of pixels, and an image, in which a signal of the peripheral pixel is a signal of a black level not higher than a predetermined level threshold, is acquired.
Claims19
An information processing apparatus comprising:
- at least one processor operatively coupled to a memory, serving as:
- a determination unit configured to acquire an image including a target pixel as a pixel of a local positive peak signal and captured by a photon-counting image sensor;
- an interpolation unit configured to interpolate an interpolation signal to a peripheral pixel as a pixel around the target pixel of the image;
- and
- a reduction unit configured to reduce noise of the image in which the interpolation signal has been interpolated,
- wherein the local positive peak signal spreads over a plurality of pixels, and
- an image, in which a signal of the peripheral pixel is a signal of a black level not higher than a predetermined level threshold, is acquired.
An information processing method comprising:
- acquiring an image including a target pixel as a pixel of a local positive peak signal and captured by a photon-counting image sensor;
- interpolating an interpolation signal to a peripheral pixel as a pixel around the target pixel of the image;
- and
- reducing noise of the image in which the interpolation signal has been interpolated,
- wherein the local positive peak signal spreads over a plurality of pixels, and
- an image, in which a signal of the peripheral pixel is a signal of a black level not higher than a predetermined level threshold, is acquired.
A non-transitory computer-readable storage medium storing a computer program for causing, when loaded and executed by a computer, the computer:
- to acquire an image including a target pixel as a pixel of a local positive peak signal and captured by a photon-counting image sensor;
- to interpolate an interpolation signal to a peripheral pixel as a pixel around the target pixel of the image;
- and
- to reduce noise of the image in which the interpolation signal has been interpolated,
- wherein the local positive peak signal spreads over a plurality of pixels, and
- an image, in which a signal of the peripheral pixel is a signal of a black level not higher than a predetermined level threshold, is acquired.
