Abstract
An image processing apparatus includes an image acquirer configured to acquire a first image that is generated by image capturing and includes information of light intensity distributions obtained with a plurality of different exposures provided with transmittance distributions that are different from one another, an information acquirer configured to acquire information on the transmittance distributions, and an image estimator configured to separate image signals corresponding to two or more exposures among the plurality of exposures from the first image in the same pixel based on an estimation using the information on the transmittance distributions, and to generate two or more second images using the separated image signals.
Claims11
An image processing apparatus comprising:
- at least one processor connected to a memory, the at least one processor being configured to:
- acquire a first image that is generated by image capturing and includes information of light intensity distributions obtained with a plurality of different exposures provided with transmittance distributions that are different from one another;
- acquire information on the transmittance distributions;
- and
- separate image signals corresponding to two or more exposures among the plurality of exposures from the first image in the same pixel based on an estimation using the information on the transmittance distributions, and to generate two or more second images using the separated image signals.
An image capturing apparatus comprising:
- at least one processor connected to a memory, the at least one processor being configured to:
- generate a captured image that includes information of light intensity distributions obtained with a plurality of different exposures provided with transmittance distributions that are different from one another
- acquire a first image that is generated by image capturing and includes information of light intensity distributions obtained with a plurality of different exposures provided with transmittance distributions that are different from one another;
- acquire information on the transmittance distributions;
- separate image signals corresponding to two or more exposures among the plurality of exposures from the first image in the same pixel based on an estimation using the information on the transmittance distributions;
- generate two or more second images using the separated image signals;
- and acquire the captured image as the first image.
A non-transitory computer-readable storage medium which stores a program configured to enable a computer to execute image processing, the image processing comprising:
- acquiring a first image that is generated by image capturing and includes information of light intensity distributions obtained with a plurality of different exposures provided with transmittance distributions that are different from one another;
- acquiring information on the transmittance distributions;
- and
- separating image signals corresponding to two or more exposures among the plurality of exposures from the first image in the same pixel based on an estimation using the information on the transmittance distributions, and generating two or more second images using the separated image signals.
