Patents by Inventor Yukihiko Yasui

Yukihiko Yasui has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Solid-state image pickup device having analog-digital converters configured to sum values of multiple pixels in the array and method for driving the same
    Patent number: 7623173
    Abstract: A CMOS image sensor includes column-parallel ADCs. Each of the ADCs includes a comparator and an up/down counter. With this configuration, digital values of pixels in a plurality of rows can be added without using additional circuits, such as an adder and a line memory device, and the frame rate can be increased while maintaining constant sensitivity.
    Type: Grant
