摘要： An imaging apparatus includes a pixel that generates charge; an integral amplifier that integrates charge transferred from the pixel; a low pass filter to which output of the integral amplifier is supplied and whose time constant is variable; first and second sample-and-hold circuits that sample and hold output of the low pass filter before and after the charge is transferred from the pixel to the integral amplifier, respectively; a differential circuit that outputs a difference between signals held by the first and second sample-and-hold circuits; and a control circuit that changes the time constant. The control circuit decreases the time constant after the sampling by the first sample-and-hold circuit ends, and increases the time constant in the middle of the sampling by the second sample-and-hold circuit.

摘要： An image sensor that has a plurality of pixels within a pixel array coupled to a control circuit and to one or more subtraction circuits. The control circuit causes an output transistor coupled to a pixel to provide a first reference output signal, a common reset output signal, and a first sense-node reset output signal, between which a subtraction circuit may form a weighted difference to create a noise signal. The control circuit causes the output transistor to provide a second sense-node reset output signal, a light response output signal and a second reference output signal, between which a subtraction circuit may form a weighted difference to create a normalized light response signal. The light response output signal corresponds to the image that is to be captured by the sensor. The noise signal is subtracted from the normalized light response signal to generate a de-noised signal.
