Title: Picture information reduction device
Inventor: KOYANAGI IZUMI
IPC: G06T3/40
Filed: 1987-05-07
Abstract: PURPOSE:To reduce picture information without causing a remarkable defect by interleaving a data at a present point of time when a data for one bit before and a data at present time are coincident within prescribed bits. CONSTITUTION:The input data 6 by one bit is stored alternately in storage sections 11, 12 and both the storage data are compared by a storage control section 3. When both the storage data, that is, the consecutive 2-bit of the one preceding bit and the data at present point of time are identical, since an enable 8 outputted from the control section 3 to one Line storage section 9 shows a value representing data ineffective period and the data at present time is not stored in the storage section 9, the data at present time is interleaved. On the other hand, when the consecutive two-bit data is not identical the enable 8 is a value representing the effective period and the dat at present time is stored in the storage section 9.
