摘要： An image sensor may include an array of image pixels arranged in rows and columns. Image pixels arranged along the same column may be coupled to a column line. The column line may be coupled to anti-eclipse control circuitry. In one suitable arrangement, the anti-eclipse control circuitry may include a data converter and an eclipse condition judgment circuit. The eclipse condition judgment circuit may be configured to record pixel output values at different points in time and to compare the recorded data to a predetermined threshold to determine whether an eclipse condition is satisfied. In another suitable arrangement, the anti-eclipse control circuitry may include a comparator and an eclipse condition judgment circuit. The comparator may compare a temporarily elevated pixel output value to a reference voltage to determine whether the eclipse condition is satisfied. In either arrangement, a maximum pixel level may be output when the eclipse condition is met.

摘要： An imager includes a column line connected to a pixel array for providing a pixel output signal. The pixel output signal is sampled during reset and readout phases. An analog-to-digital converter (ADC), which is coupled to the column line, samples the pixel output signal and provides a digital output signal. The ADC is configured to sample the pixel output signal twice, during the reset phase, in order to detect eclipse in the pixel output signal. The ADC includes a comparator, sequentially operated by a reset control, for comparing a first pixel output voltage and a second pixel output voltage, respectively, during the reset phase. The comparator is configured to provide an output bit indicating detection of an eclipse, based on a difference between the first and second pixel output voltages.
