Toshihiro Watanabe is a prominent inventor based in Kuwana, Japan. He has made significant contributions to the field of image reading technology, holding a total of 8 patents. His work has greatly influenced the efficiency and accuracy of document processing systems.

Latest Patents

Watanabe's latest patents include an image reading system configured to detect document edges. This innovative system comprises a reading device, a first calibration unit, and a detection unit. The reading device is designed to read a white reference member to acquire white image data and to read an original document to obtain document image data. The first calibration unit calibrates the shading of the document image data, generating first image data by converting density values to gradation values within a predetermined range. The detection unit identifies pixels in the image data that correspond to the edges of the original document.

Another notable patent is an image-reading device that detects the edge of a sheet by dynamically setting a mask region. This device reads an image of a sheet while it is being conveyed. It sets target lines in the image to search for an edge pixel that represents the sheet edge. The detection unit searches for the edge pixel by referring to the target lines and detects its positional coordinates from pixels outside the mask. This dynamic setting of the mask region enhances the accuracy of edge detection.
