Latest Patents

One of Bonatto's latest patents is for a "Color image reacting apparatus having a non-uniformity correction ROM." This invention utilizes a charge coupled device (CCD) to provide serialized signals from a document line to an A/D converter. To address issues such as lighting non-uniformity and variations in CCD cell response, a reference strip is read prior to each document reading. The digital values from this reference strip are stored in RAM and compared with the values read from the document, allowing for compensated values to be generated for a half-tone generator. This process ensures that the output is accurately coded, taking into account various color selections through a multiplexer.

Another significant patent is for a "Digital reading device for facsimile apparatus." In this invention, a document line is focused onto a series of reading elements, such as CCD cells, which produce a serial output signal for an analogue-to-digital converter. To counteract the fall-off in transfer function at high spatial frequencies, the signal undergoes processing through a multi-stage filter before A/D conversion. This includes adjustable band pass stages for setting levels and an intermediate stage that eliminates sampling noise, ensuring high-quality signal matching.
