The invention relates to a mop plate state display mechanism. The mop disc state display mechanism comprises a moving block, a reset piece and a moving groove, the moving block is arranged in a mop disc, a sliding block is arranged at the upper end of the moving block, a color body is arranged on the sliding block, and the moving block moves outwards through centrifugal force generated by rotation of the mop disc; the reset piece is arranged on the moving block and used for resetting the moving block. The moving groove is formed in the upper end of the mop disc and is a through groove, and the sliding block is inserted into the moving groove to move back and forth. After the structure is adopted, through cooperation of the moving blocks, the sliding blocks and the moving grooves, the overall structure is simpler and more reasonable, the service life can be greatly prolonged, meanwhile, sliding of the sliding blocks in the moving grooves is more convenient, and the color rings move from inside to outside and are more gorgeous.

The invention discloses a method for improving color gathering of a heat shrink film, and relates to the technical field of heat shrink film printing. According to the method, the shrinkage ratio of each segment is accurately calculated by measuring the reference perimeter of a low-shrinkage area and the segment perimeter of a high-shrinkage area of a bottle body; making a T ruler strip based on an association rule of a shrinkage ratio and a dot ratio, and positioning a to-be-compensated area through a thermal shrinkage test; and in combination with a color density partition compensation coefficient and an exclusive compensation formula, dot accurate compensation is realized.

Specific syntax elements define a target colour volume resulting from some post-decoding processing on pictures in a video coding system. An encoded video bitstream carries these syntax elements from an encoding device to a decoding device using one or more Supplemental Enhancement Information (SEI) messages, such as a Target Colour Volume Information (TCVI) message or a modified Content Colour Volume (CCV) message. Each SEI message comprises metadata defining a target colour volume and a unique identifier. This allows the decoding device to select one of the SEI messages by comparing its unique identifier with an identifier for a desired post-decoding processing. Upon finding a match, the decoder applies the corresponding post-decoding processing to a decoded picture in accordance with the metadata of the selected target colour volume. An encoding method, a decoding method, an encoding apparatus, and a decoding apparatus are described.
