Abstract: PURPOSE:To improve accuracy for a motion vector by interpolating the value of motion vectors only for which high possibility as an error is judged by peripheral vectors. CONSTITUTION:A horizontal direction mean value VLRx is found from the vectors VRx and VLx of right and left blocks by an adder 7 and a 1/2 coefficient multiplier 8. Similarly, a vertical direction component VLRy is found from vectors VLRy, VLy by an adder 9 and a 1/2 coefficient multiplier 10. Those constituents 7-10 comprise a vector averaging circuit 11. A switch 12 selects VLRx and VLRy when a control signal SEL shows a logic level 1 and Vcx, Vcy when it shows a logic level O, respectively according to SEL, and set the vector at an output vector V0. While, the AND of signals C12, C3 and C4 is taken by an AND gate 25, and it is set as the control signal of the switch 12. In other words, when the error of a center vector VC is larger than that of right and left vectors VL, VR the center vector is deleted, and interpolation is performed by the mean value of the right and left vectors.

Title: Semiconductor device
Inventor: NAKATSUKA MASANORI
IPC: H01L23/28
Filed: 1987-06-26
Abstract: PURPOSE:To prevent thermal stress from being created in gel resin and to prevent a semiconductor element and leads from being subjected to external force, by making a case higher than the gel resin so as to define space between a cover and the gel resin. CONSTITUTION:A case 12 is higher than a gel resin 13, so that space is defined between a cover 14 and the resin 13.

Thus, creation of thermal stress in the resin 13 can be prevented effectively. In this manner, the element 1 and lead lines 8 can be prevented from being subjected to external force by the effect of the resin 13.
