Abstract
Image processing with reduced data size of a RAW image while suppressing a deterioration in image quality of a developed image is disclosed. In one example, an input unit of a touch panel acquires a development size corresponding to an image size at the time of development of the RAW image. A lossy compression unit compresses the captured image at a compression ratio corresponding to the development size and by a compression method that compressing an image by decomposing the image into a plurality of spatial frequency components to generate the RAW image. The compression ratio increases as the development size decreases. The technology can be applied to, for example, an imaging device that captures an image and records a RAW image or the like.
Claims15
An imaging device comprising:
- an acquisition unit that acquires a development size corresponding an image size at a time of development of a RAW image;
- and
- a compression unit that compresses a captured image at a compression ratio corresponding to the development size acquired by the acquisition unit and by a compression method that compresses an image by decomposing the image into a plurality of spatial frequency components to generate the RAW image,
- wherein
- the compression ratio increases as the development size decreases.
An imaging method comprising:
- by an imaging device,
- acquiring, a development size corresponding an image size at a time of development of a RAW image;
- and
- compressing, a captured image at a compression ratio corresponding to the development size acquired in the acquiring and by a compression method that compresses an image by decomposing the image into a plurality of spatial frequency components to generate the RAW image,
- wherein
- the compression ratio increases as the development size decreases.
A program causing a computer to function as an imaging device, the imaging device comprising:
- an acquisition unit that acquires a development size corresponding to an image size at a time of development of a RAW image;
- and
- a compression unit that compresses a captured image at a compression ratio corresponding to the development size acquired by the acquisition unit and by a compression method that compresses an image by decomposing the image into a plurality of spatial frequency components to generate the RAW image,
- wherein
- the compression ratio increases as the development size decreases.
An image processing method comprising:
- by an image processing device,
- acquiring, size information indicating a development size corresponding to an image size at a time of development of a RAW image, and the RAW image corresponding to a captured image compressed at a compression ratio corresponding to the development size and by a compression method that compresses an image by decomposing the image into a plurality of spatial frequency components;
- and
- developing, the RAW image acquired in the acquiring to generate a developed image with the development size indicated by the size information acquired in the acquiring by decompressing the RAW image on a basis of the development size,
- wherein
- the compression ratio increases as the development size decreases.
A program causing a computer to function as an image processing device, the image processing device comprising:
- an acquisition unit that acquires size information indicating a development size corresponding to an image size at a time of development of a RAW image, and the RAW image corresponding to a captured image compressed at a compression ratio corresponding to the development size and by a compression method that compresses an image by decomposing the image into a plurality of spatial frequency components;
- and
- a development unit that decompresses the RAW image acquired by the acquisition unit to generate a developed image with the development size indicated by the size information acquired by the acquisition unit on a basis of the development size,
- wherein
- the compression ratio increases as the development size decreases.
