Title: Digital image data compression coding/decoding method, its equipment and storage medium
Inventor: JEONJIN LEE
IPC: H04N19/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To attain simple coding at a high compression rate by splitting image data into blocks and applying compression coding to each block through the use of a BMI of each block. SOLUTION: Digital image data are divided into blocks each consisting of M1 ×M1 pixels, each block is discriminated as to whether each block is an edge block or other intermediate block and the intermediate block is compression-coded in the 1st process. In the 2nd process, each edge block is divided into blocks consisting of M2 ×M2 pixels which are smaller than the of M1 ×M1 pixels (M1 >M2 ), edge blocks and intermediate blocks are distinguished by the same method as the 1st process, a closest pattern is selected among M2 ×M2 pixel patterns prepared in advance in the case of edge blocks, its index, a size of BGV, and a mean value of edge block data are coded. In the 3rd process, intermediate blocks of the M2 ×M2 pixel blocks are compression-coded.  Moreover, in the 4th process, a code to identify the intermediate block of the 1st block from the edge block of the 2nd block is added. The intermediate blocks in the 1st and 2nd processes are coded by using only their BMI.

Abstract: PURPOSE:To reduce collision sounds of ejected washing water leaked from the clearance between the washing tank of a dish washer and the lid thereof for reduction of washing noises by providing a frame with a lip in the clearance between the lid and the flange provided at the opening of a washing tank in the outside of a packing, and also by providing a double seal structure with a conventional packing. CONSTITUTION:A flange 2a is equipped at a washing tank 2, and a base 7a and as the fitting part to the washing tank 2 a soft lip 7b are equipped in a frame 7. A protrusion 6a is provided at the opposite position against the packing 4 of the lid 6. The packing 4 is pressed by this protrusion 6a of the lid 6 to seal the ejected washing water of the washing tank 2. When the dish washer is driven to start running to wash dishes, the washing water ejected to the washing tank 2 collides with table wares to make sounds. The collided sounds of ejected washing water are reduced by the packing 4, but lead to the clearance between the washing tank 2 the lid 6. But, since the lid 6 contacts the soft lip 7b of the frame 7, the collided sound leaked from the ejected washing water can be reduced with little leakage.
