摘要:
In a state that a plurality of capacitances are connected between input and output nodes of an amplifier, a short circuit is established between the input and output nodes of the amplifier. In a state that at least one of the capacitances is isolated from the input and output nodes of the amplifier, the plurality of capacitances are connected to the input and output nodes of the amplifier, in a case that an output from the amplifier is larger than a threshold.

Disclosed is a sensor device with pixels that in addition to sensing an image, performs captured image or scene analysis. The device saves further image processing downstream, is characterized by minimal charge movements and reduces a large fraction (about 90%) of the consumed electric energy as compared to the existing devices.

Each sense circuit is configured to read out electrical signals from at least one pixel associated with the sense circuit in order to generate data representing whether or not photons have been received by the sense circuit. The count circuit is in communication with a sense circuit selected from the plurality of sense circuits. The count circuit is configured to provide integration results for the pixels associated with the sense circuits based on the data received from the sense circuits.

An image sensor has a per-column ADC arrangement including first and second capacitors for correlated double sampling, and a comparator circuit. The capacitors are continuously connected to, respectively, the analog pixel signal and a ramp signal without use of a hold operation. The comparator circuit comprises a differential amplifier having one input connected to the junction of the two capacitors and another input connected to a reference signal. The reference signal is preferably sampled and held from a reference voltage. The use of a differential amplifier as first stage of the comparator addresses problems arising from ground voltage bounce when a large pixel array images a scene with low contrast.

摘要:
When a level of a signal output from a pixel (10-1) is higher than a comparison level (VREF), the signal output from the pixel (10-1) is converted into a digital signal during a first period (Tu-H) by using a first reference signal (VH). If the level of the signal output from the pixel (10-1) is lower than the comparison level (VREF), the signal output from the pixel (10-1) is converted into a digital signal during a second period (Tu-L) that is longer than the first period (Tu-H) by using a second reference signal (VL).
