专利汇可以提供Picture inputting system专利检索,专利查询,专利分析的服务。并且PURPOSE: To utilize effectively a picture memory and to execute a processing at a high speed by designating optionally a head address onto the picture memory in case when a picture on a business form is written in the picture memory, compressing and transferring a read-out from the picture memory, and executing a parallel processing of write and read-out.
CONSTITUTION: A picture 11 on a business form 1 is scanned by using an appropriate optical means 2. The obtained picture data is written successively onto a picture memory 5 as a binary picture data by a binary-coding circuit 3, designating a head address with regard to each of the business form by using a direct memory access DMA. Also, as soon as the write onto the memory 5 has ended with regard to the business form of at least one sheet or more, the picture data stored in the memory 5 is read out successively, and the read-out picture data is encoded and compressed by a run length encoding system in a compressing circuit 6. This compressed data is transferred to a hot computer through an interface circuit 9.
