AI Technical Summary
Technical Problem
Existing imaging devices struggle to efficiently record and playback High Dynamic Range (HDR) images due to compatibility issues and increased data size, leading to potential loss of image quality and compatibility with various devices.
Method used
The method involves dividing HDR image data into segmented data, encoding each segment in High Efficiency Image File Format (HEIF), and recording it as a single file with metadata for reconstruction, ensuring alignment with device capabilities and compatibility.
Benefits of technology
This approach allows for efficient recording and playback of HDR images with high resolution, maintaining image quality and compatibility across different devices by adhering to standard encoding formats.

Abstract
To record an image in a recording form suitable for recording and reproduction when recording an image having a large data amount like an HDR image.SOLUTION: A control method of an imaging apparatus includes a coding step of dividing HDR image data obtained by imaging by an imaging sensor into a plurality of pieces of divided HDR image data and encoding the plurality of pieces of divided HDR image data, respectively, a recording control step of recording a plurality of pieces of divided HDR image data encoded in an HEIF format as an image item in one image file and recording image structure information for combining the plurality of pieces of divided HDR image data into a state before division as a derived image item in the image file, and a setting step of setting a recording mode. The vertical and horizontal sizes of the divided HDR image data differ depending on the vertical and horizontal sizes of the image corresponding to the recording mode set in the setting step.SELECTED DRAWING: Figure 3
