Abstract
A moving picture encoding method for increasing coding efficiency includes: determining whether or not to apply orthogonal transformation, to calculate a value of an orthogonal transform skip flag; performing the orthogonal transformation on a prediction residual according to the value of the orthogonal transform skip flag, to calculate at least one orthogonal transform coefficient; performing quantization on at least the one orthogonal transform coefficient, to calculate at least one quantized coefficient; performing variable-length encoding on the orthogonal transform skip flag; and changing a scan order for at least the one quantized coefficient according to the value of the orthogonal transform skip flag, and performing variable-length encoding on at least the one quantized coefficient in the scan order after the change.
