Abstract: A logarithmic response digital pixel sensor comprises a linear light detecting unit, an exponential producer, a counting unit, a comparator and a memory unit. The logarithmic response digital pixel sensor is used for detecting light via the linear light detecting unit for producing a linear analogy detecting signal. The exponential producer is used for providing an exponential reference signal. The comparator is used for comparing the linear analogy detecting signal with the exponential reference signal and outputting a comparison result to the memory unit. The memory unit is used for producing a logarithmic response digital signal by processing the comparison result and a count reference signal provided from the counting unit. Thereby, the present invention improves upon the drawbacks of the traditional logarithmic response analogy image sensor, and simplifies the design of the back image sensor processing circuit.

Abstract: A digital image sensor and noise cancellation operation method reduces noise of an analog sensor circuit inside a digital image sensor and simplifies the complex design of an analog/digital signal of the prior art. The present invention provides a novel digital image sensor for converting at least one analog noise signal to at least one digital noise signal outputted via an analog/digital converter. The digital noise signal is written to a memory and compared with the original digital image signal for generating at least one image signal clearly. The digital image sensor of the present invention is replaced with an analog correlated double sampling circuit for canceling out noise.
