Latest Patents

Wanatabe holds a patent for an "Output-compensating device and method of an image sensor." This invention involves an output compensating device that utilizes multiple light-sensor circuits, each representing a unit pixel. The device operates by generating a sensor current proportional to the light falling on the photoelectric converting element. It converts this current into a voltage signal using the sub-threshold region characteristic of a transistor with a logarithmic output characteristic. This method allows the image sensor to compensate for variations in pixel output by adjusting the gate and drain voltages of the transistor, even in the absence of actual light.
