Abstract
An image capture device for recording HDR (high dynamic range) image data obtained through image capture performs control so as to, when encoding HDR image data obtained by capturing an image with an image sensor, divide part of the HDR image data corresponding to a coding area to be encoded into a plurality of divided HDR image data, encode each of the plurality of divided HDR image data by using encoding means, and record the plurality of divided HDR image data that are encoded on a recording medium in a predetermined recording format.
Claims25
An image capture device for recording HDR (high dynamic range) image data obtained through image capture, comprising:
- an image sensor;
- a memory and at least one processor which functions as:
- encoding means for encoding HDR image data obtained by capturing an image data with the image sensor;
- and
- recording control means for dividing a part of the HDR image data captured by the image sensor, corresponding to a coding area to be encoded, into a plurality of divided HDR image data, encoding each of the divided HDR image data by using the encoding means, and recording the plurality of encoded divided HDR image data on a recording medium in a predetermined recording format,
- wherein the recording control means performs control to record, as a single image file, the plurality of divided HDR image data that are encoded on the recording medium in the predetermined recording format, and
- wherein the recording control means performs control to record, as a derived image item, image structure information which is used to combine the plurality of divided HDR image data into HDR image data before being divided in the single image file together with the plurality of divided HDR image data.
A method for controlling an image capture device, the image capture device including an image sensor for capturing an image data and recording HDR (high dynamic range) image data obtained through image capture, the method comprising:
- dividing a part of the HDR image data captured by the image sensor corresponding to a coding area to be encoded into a plurality of divided HDR image data;
- encoding each of the plurality of divided HDR image data by using the encoding means;
- and
- recording, as a single image file, the plurality of encoded divided HDR image data on a recording medium in a predetermined recording format,
- wherein, in the recording, image structure information which is used to combined the plurality of divided HDR image data into HDR image data before being divided is recorded as a derived image item in the single image file together with the plurality of divided HDR image data.
An image capture device for recording HDR (high dynamic range) image data obtained through image capture, comprising:
- an image sensor;
- a memory and at least one processor which function as:
- encoding means for encoding HDR image data obtained by capturing an image data with the image sensor;
- and
- recording control means for dividing a part of the HDR image data captured by the image sensor, corresponding to a coding area to be encoded, into a plurality of divided HDR image data, encoding each of the divided HDR image data by using the encoding means, and recording the plurality of encoded divided HDR image data on a recording medium in a predetermined recording format,
- wherein when recording an HDR image data, the recording control means performs control to divide the HDR image data captured by the image sensor into the plurality of divided HDR image data, compression-encode each of the plurality of divided HDR image data into an HEVC (High Efficiency VideoCoding) format by using the encoding means, and record, in the predetermined recording format, the plurality of divided HDR image data that are compression-encoded, and
- wherein when recording an SDR image data, the recording control means performs control to compression-encode the SDR image data obtained by capturing an image data with the image sensor in a JPEG format without dividing the SDR image data into a plurality of the SDR image data and record the compression-encoded SDR image data as a JPEG file.
A method for controlling an image capture device, the image capture device including an image sensor for capturing an image data and recording the image data obtained through image capture, the method comprising:
- when the recording is performed for HDR (high dynamic range) image data,
- dividing a part of HDR image data captured by the image sensor corresponding to a coding area to be encoded into a plurality of divided HDR image data;
- encoding each of the plurality of divided HDR image data into a High Efficiency Video Coding (HEVC) format;
- and
- recording the plurality of encoded divided HDR image data on a recording medium in a predetermined recording format, and
- when the recording is performed for SDR image data,
- compression-encoding for SDR image data captured by the image sensor into a JPEG format without dividing the SDR image data into a plurality of divided SDR image data, and
- recording the compression-encoded SDR image data as a JPEG file.
