Abstract
An image processing device that uses YC-raw data as a development processing target includes an image processing unit that performs conversion processing, into an image sensor output format, on YC-raw data that is image data obtained by performing pre-white balance processing, demosaicing, and a YC conversion processing on image data in the image sensor output format, and further performs reverse pre-white balance processing with respect to the pre-white balance processing and remosaicing to restore a state prior to the demosaicing.
Claims20
An image processing device comprising
- an image processing unit that performs conversion processing, into an image sensor output format, on YC-raw data that is image data obtained by performing pre-white balance processing, demosaicing, and a YC conversion processing on image data in the image sensor output format, and further performs reverse pre-white balance processing with respect to the pre-white balance processing and remosaicing to restore a state prior to the demosaicing.
An image processing device comprising
- a recording control unit that records image data in an image sensor output format or YC-raw data onto a recording medium,
- the image data having been obtained after conversion processing into the image sensor output format is performed on YC-raw data that is image data obtained by performing pre-white balance processing, demosaicing, and a YC conversion processing on image data in the image sensor output format, and reverse pre-white balance processing with respect to the pre-white balance processing and remosaicing to restore a state prior to the demosaicing are further applied,
- the YC-raw data to be recorded, having been obtained on a basis of the image data in the image sensor output format obtained after the remosaicing.
An imaging device comprising:
- an imaging unit that obtains captured image data using an image sensor;
- an image processing unit that performs pre-white balance processing, demosaicing, and YC conversion processing on image data in an image sensor output format obtained by the imaging unit to generate YC-raw data;
- and
- a control unit that performs processing to associate, with YC-raw data, sensor array information indicating a pixel array of the image sensor as metadata used in remosaicing to restore a state prior to the demosaicing, and pre-white balance information including a parameter of the pre-white balance processing as metadata used in reverse pre-white balance processing with respect to the pre-white balance processing.
An image processing method comprising
- performing conversion processing, into an image sensor output format, on YC-raw data that is image data obtained by performing pre-white balance processing, demosaicing, and a YC conversion processing on image data in the image sensor output format, and further performing reverse pre-white balance processing with respect to the pre-white balance processing and remosaicing to restore a state prior to the demosaicing.
