Latest Patents

Yamaguchi's latest patents include a front-end signal processing circuit and an imaging device. This front-end signal processing circuit stabilizes the black level of an output signal from an image sensor at a prescribed set level. It achieves this without being influenced by the DC offset component of circuit elements in the feedback loop. The circuit features a feedback loop composed of a luminance detecting/digitizing section and a black level clamp section. It effectively clamps the black level of the output signal to the desired level. Additionally, the circuit includes an offset correction section that stores an offset value, subtracts it from the digital luminance signal, and outputs the corrected signal. Another notable invention is a pipeline A/D converter that meets the resolution, conversion processing rate, and power consumption requirements of systems incorporating it. This converter includes a control section that outputs a control signal based on the operation state of the apparatus, allowing for switching of resolution and conversion processing rate.
