Latest Patents
One of his latest patents is an image sensing device designed to solve the problem of conventional image sensing devices that require much time for reading pixel signals. This device includes a first pixel unit coupled to a first vertical read line and a second pixel unit coupled to a second vertical read line. It features a first transfer switch and a second transfer switch that facilitate a reset process of the vertical read line using a dark level signal output from the second pixel unit. This process allows for the conversion of pixel signals into digital values efficiently.
Another notable patent is for an analog to digital converter for solid-state image pickup devices. This invention includes ADCs that can be arranged in a limited space, where the potential of a pixel signal is held at a node. A plurality of capacitors are capacitively coupled to this node, and the potential is decreased stepwise by switching the voltages of the counter electrodes of the capacitors. A comparator then determines the upper bits of a digital value, simplifying the configuration of each ADC.
