Abstract
In an intra-picture, a predetermined region is set as a normal encoding region, and a region other than the predetermined region is set as a simplified encoding region. In a subsequent picture, the normal encoding region is set as a larger region including a normal encoding region of a previous picture, and a region other than the normal encoding region is set as a simplified encoding region. In each picture, normal encoding is performed on a block of the normal encoding region, and simplified encoding in which a generated code amount and a computation amount are smaller than in the normal encoding is performed on a block of the simplified encoding region.
