Title: Osamu Takase: Innovator in Image Reading Technology
Introduction
Osamu Takase is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of image reading technology, holding a total of 7 patents. His innovative work has advanced the capabilities of image readers, enhancing their efficiency and accuracy.
Latest Patents
One of Takase's latest patents is an image reader featuring photoelectric conversion line sensors. This invention includes a light source that projects light onto an original document. The design incorporates first and second photoelectric conversion elements that read different halves of the original in a scanning direction. The first read signal is transferred from the first photoelectric conversion element, while the second read signal is transferred from the second element, both starting from the center of the original. An imaging lens projects reflected light onto these elements, and a driver circuit ensures that the read signals are output correctly. A signal processing unit then processes these signals to generate a finalized read signal containing pixel information.
Another notable patent is an image reading apparatus designed to correct dark signals. This apparatus features a photoelectric conversion element with multiple cells, including shielded cells that output only dark signals. The system generates dark signal data for each cell, which corresponds to the ratio of the image signal output under no-exposure conditions. A dark signal data memory stores this information, while a dark signal component generating system creates a dark signal component for each cell. The apparatus effectively subtracts this component from the image signal obtained under exposure conditions, improving the overall image quality.
