Title:
IMAGING DEVICE, IMAGING METHOD, PROGRAM, AND IMAGE PROCESSING METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/043054
Kind Code:
A1
Abstract:
The present invention relates to an imaging device, an imaging method, a program, and an image processing method and program that make it possible to reduce the data amount of a RAW image while suppressing image quality deterioration of a developed image if generating a RAW image through compression of a captured image by a compression scheme for decomposing an image into a plurality of spatial frequency components and performing compression. An input unit of a touch panel acquires a development size, which is an image size during development of a RAW image. An irreversible compression unit generates the RAW image by compressing a captured image by using a compression scheme for decomposing an image into a plurality of spatial frequency components and performing compression at a compression ratio corresponding to the development size. The compression ratio is greater the smaller the image size is. The present invention can be applied to an imaging device or the like that captures an image and records a RAW image, for example.
