1. An image conversion method comprising:

generating a multi-plane image reconfigured into layers in a depth direction based on multiple pieces of multi-view image data;

generating an aggregated layer by aggregating the layers of the multi-plane image into at least one layer such that respective regions of pixels on each layer are packed into the at least one aggregated layer without overlapping between the respective regions of pixels; and

converting a multi-plane image including the aggregated layer into a two-dimensional (2D) atlas image.
