Abstract
An imaging processing system includes an image pickup device that has circuitry which creates, from raw image data, image data including a first gamut, and compression-codes the image data including the first gamut to generate compression-coded image data. The system also includes an image processing device that has circuitry which decodes the compression-coded image data to generate uncompressed image data, which includes the first gamut. The circuitry of the image processing device also converts the uncompressed image data including the first gamut into image data including a second gamut, where the first gamut encompasses the second gamut.
Claims17
An imaging processing system, comprising:
- an image pickup device including an image sensor configured to output raw image data, and first circuitry configured to:
- receive, over a transmission path, gamut information from a decoder of an image processing device that is communicatively coupled with the image pickup device, the gamut information indicating a plurality of kinds of gamut supported by the image processing device;
- set a first gamut for the image pickup device according to the received gamut information, the set first gamut being one of the received plurality of kinds of gamut received from the image processing device;
- convert the raw image data output from the image sensor into converted image data having the first gamut;
- compression-code the converted image data to generate compression-coded image data;
- and
- transmit, over the transmission path to the decoder of the image processing device, the compression-coded image data and metadata indicating the first gamut;
- and
- the image processing device including second circuitry configured to
- select a second gamut;
- extract, from a memory of the image processing device, based on the metadata, stored conversion information to convert an image having the first gamut to an image having the second gamut;
- and
- decode and convert the compression-coded image data into image data having the second gamut using the extracted conversion information.
An image processing method, comprising:
- receiving, over a transmission path by processing circuitry of an image pickup device that includes an image sensor configured to output raw image data, gamut information from an image processing device that is communicatively coupled with the image pickup device, the gamut information indicating a plurality of kinds of gamut supported by the image processing device;
- setting a first gamut for the image pickup device according to the received gamut information, the set first gamut being one of the received plurality of kinds of gamut received from the image processing device;
- converting, by the processing circuitry of the image pickup device, the raw image data output from the image sensor into converted image data having the first gamut;
- compression-coding the converted image data to generate compression-coded image data;
- transmitting, over the transmission path to a decoder of the image processing device, the compression-coded image data and metadata indicating the first gamut,
- selecting a second gamut;
- extracting, from a memory of the image processing device, based on the metadata, stored conversion information to convert an image having the first gamut to an image having the second gamut;
- and
- decoding and converting the compression-coded image data into image data having the second gamut using the extracted conversion information.
A non-transitory computer-readable medium encoded with computer-readable instructions thereon, the computer-readable instructions, when executed by processing circuitry of an image pickup device that includes an image sensor configured to output raw image data, cause the processing circuitry to perform a method comprising:
- receiving, over a transmission path, gamut information from an image processing device that is communicatively coupled with the image pickup device, the gamut information indicating a plurality of kinds of gamut supported by the image processing device;
- setting a first gamut for the image pickup device according to the received gamut information, the set first gamut being one of the received plurality of kinds of gamut received from the image processing device;
- converting the raw image data output from the image sensor into converted image data having the first gamut;
- compression-coding the converted image data to generate compression-coded image data;
- transmitting, over the transmission path to a decoder of the image processing device, the compression-coded image data and metadata indicating the first gamut,
- selecting a second gamut;
- extracting, from a memory of the image processing device based on the metadata, stored conversion information to convert an image having the first gamut to an image having the second gamut;
- and
- decoding and converting the compression-coded image data into image data having the second gamut using the extracted conversion information.
