Latest Patents

Itoh’s latest patents revolve around advanced image processing devices. One patent introduces an image processing apparatus and method that operates in both variable and fixed modes. In variable mode, the quantizing values and thresholds can be adjusted to change the surface gray levels of a printable image while keeping a consistent laser gradation value. The fixed mode utilizes constant thresholds to maintain quality. This dual-mode functionality not only simplifies the printing operation but also ensures consistent image quality even amidst environmental variations.

The second patent addresses the issue of pulse variation when driving printers, significantly enhancing the gray level representation in printed images. By using a gray level image processing circuit which processes two pixels at a time, the system can discriminate edge portions from non-edge areas. This allows for corrective enhancements on edge data while maintaining optimal quality on non-edge pixels, effectively eliminating dot displacement issues due to pulse variations.
