Method and apparatus for storing, processing and reconstructing full resolution image out of sub band encoded images

An apparatus comprising:

• a display;
• and
• at least one processor configured to:
• obtain a captured image having a resolution which is higher than a display resolution of the display,
• create a low resolution image of the captured image based on the display resolution of the display,
• extract a sub-band information associated with the low resolution image,
• encode the sub-band information,
• store, in a buffer of the apparatus in a single data file format, the low resolution image, the encoded sub-band information, and at least one parameter regarding at least one of the creating of the low resolution image, the extracting of the sub-band information, or the encoding of the sub-band information,
• cause the display to display the low resolution image,
• modify the at least one parameter independently from the displaying of the low resolution image while displaying the low resolution image,
• storing the modified at least one parameter in the buffer,
• receive a selection of the low resolution image,
• decode the encoded sub-band information associated with the low resolution image based on the at least one parameter,
• reconstruct a high resolution image of the captured image based on the low resolution image and the decoded sub-band information, and
• store, in a storage of the apparatus, the reconstructed high resolution image,
• wherein the low resolution image has a resolution that is lower than a resolution of the captured image and the high resolution image has a resolution that is higher than that of the low resolution image, and
• wherein the at least one parameter comprises a photo editor effect that is applied to the low resolution image without applying an impact of the photo editor effect on the sub-band information.
