Title: Picture data processor
Inventor: KAWAKAMI KATSURA
IPC: G06T3/00
Filed: 1983-05-19
Abstract: PURPOSE:To speed up processing and reduce device constitution by enlarging and reducing a picture by addition without employing multiplication. CONSTITUTION:A remainder register 52 adds the current remainder R to the ratio value alpha in a ratio value register 51 through an adder 53. The register 52 obtains the calculation result shown in a list 1. Then, the contents of a result register 56 are shifted to left at a point S1 and bit information (a) corresponding to picture information P1 is transferred from a register 55 to the register 56. Subsequent processing is performed similarly. A carry detection part 54 does not make a shift at a point S4 and bit information (d) is not written in the register 56. Information (e) is held as original picture information P5 again in the register 56 at a point S5. Similarly, pieces of information (f), (g), and (h) are sent out of the register 55 as pieces of information P6, P7, and P8, and only the pieces of information (f) and (g) are held in the register 56 as pieces of shift picture information Q5 and Q6. Thus, the picture is reduced to 6/8. Enlargement is the same.
