Abstract:
A video image decoding device ( 1 ) is equipped with a TT information decoder ( 14 ) that, in the case where encoded data includes merge/skip information that merges or skips presence information indicating whether or not frequency-domain transform coefficients are included in the quantized transform coefficients, does not decode the presence information, and a TT information inference unit ( 33 ) that, in the case where the encoded data includes merge/skip information that merges or skips the presence information, infers the presence information. The TT information decoder ( 14 ) uses presence information inferred by the TT information inference unit ( 33 ) to decode the encoded and quantized transform coefficients.

Claim (Index 2):
An image decoding device comprising:\n a memory; a processor, wherein the processor configured to perform steps of (a) and (b); (a) inferring non-zero transform coefficient presence information indicating whether or not non-zero transform coefficients are included in a second block of quantized transform coefficients or decoding the non-zero transform coefficient presence information from encoded data, and (b) decoding the quantized transform coefficients, wherein the second block of quantized transform coefficients is obtained by splitting a transform unit and consists of 4\u00d74 quantized transform coefficients, in a case where a target second block is, in a processing order, the second block lastly processed in a corresponding the transform unit, the non-zero transform coefficient presence information is inferred that the non-zero transform coefficients are present within the second block, and in the case where the non-zero transform coefficient presence information indicates that non-zero transform coefficients are present within the second block, decoding quantized transform coefficients within that second block from the encoded data, wherein the transform unit includes at least 16\u00d716 and 32\u00d732 as candidates of the transform unit size.
