Encoding apparatus, encoding method, and storage medium

An encoding method executed by an encoding apparatus, comprising:

• obtaining a plurality of first pixel values and a plurality of second pixel values generated by an image sensor and corresponding to a plurality of pixels, a first gain being applied to each of the plurality of first pixel values and a second gain greater than the first gain being applied to each of the plurality of second pixel values;
• and
• encoding each of a plurality of target pixel values on the basis of a correlation with a reference pixel value corresponding to a same pixel among a plurality of reference pixel values, wherein the plurality of target pixel is one of the plurality of first pixel values and the plurality of second pixel values, and the plurality of reference pixel values is the other of the plurality of first pixel values and the plurality of second pixel values.

A non-transitory computer-readable storage medium which stores a program for causing a computer to execute an encoding method comprising:

• obtaining a plurality of first pixel values and a plurality of second pixel values generated by an image sensor and corresponding to a plurality of pixels, a first gain being applied to each of the plurality of first pixel values and a second gain greater than the first gain being applied to each of the plurality of second pixel values;
• and
• encoding each of a plurality of target pixel values on the basis of a correlation with a reference pixel value corresponding to a same pixel among a plurality of reference pixel values, wherein the plurality of target pixel is one of the plurality of first pixel values and the plurality of second pixel values, and the plurality of reference pixel values is the other of the plurality of first pixel values and the plurality of second pixel values.
