Title: Image processor
Inventor: HIROTA YOSHIHIKO
IPC: G06T1/00
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To quicken a feedback of multi-valued error diffusion by allowing a quantization error data detection section to retrieve a quantization error data detection table with output data of a feedback adder used for an address to obtain a quantization error thereby simplifying the circuit configuration. SOLUTION: In the continuous gradation error diffusion processing, an adder 514 adds feedback error data ED 47-70 whose error is spread to input data ED 17-10 to provide an output of a sum ED 28-20. A quantization error data detection table 518 consisting of a RAM table receives data by using the sum ED 28-20 as an address to obtain gradation error data ED 37-30 within a gradation range matching with a threshold level (=1, 8, 16, 32, 48, 64, 80, 96, 128, 144, 160, 176, 192, 224, 255) in a 4-bit code processing section 517. An error integral matrix 51B applies error weight integration processing to pixels around a target pixel to generate the feedback error data ED 47-70, which are fed to the adder 514.

Title: Electrode for plating, plating device and plating method
Inventor: MATSUMOTO TAKESHI
IPC: C25D17/12
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To suppress variation in plating thickness in a body to be plated. SOLUTION: An electric field between an anode electrode 1 and an wafer 3 to be plated becomes small at the central part of jetting of a plating liq. 6, becomes large at the outer peripheral part and distribution is generated in the electric field, too by generating the distribution of potential which makes the potential low in a central region of the anode electrode 1 and make the potential high in an outer peripheral region at the time of applying the voltage when the central region of the anode electrode 1 is made as an anode part of a low conductive material and the outer peripheral part of the electrode is made as an anode part of a high conductive material. Thus, the movement capacity of ions in the direction of the wafer becomes small compared with that around the jetting of the plating liq. as the electric field is small at the center of the jetting of the plating liq. at a high flow rate. Thus, the quantity of ions reaching the surface of the wafer within a fixed time becomes small at the center of the jetting compared with that in the conventional constitution. Consequently, a uniformly plated layer, in which the plating thickness does not become thick at the center, is formed corresponding to such a quantity distribution of the ions on the wafer.
