Original Abstract Submitted
an image encoding apparatus for encoding an image comprises a generation unit configured to generate, from a first quantization matrix having a size of n�n (n is a positive integer), a second quantization matrix having a size of p�q (p and q are positive integers which satisfy p<n<q, and the size of p�q indicates a size of p in a horizontal direction and a size of q in a vertical direction), and a quantization unit configured to quantize transformation coefficients in a sub-block having a size corresponding to the size of p�q using the second quantization matrix.
