    摘要: An apparatus and method for reducing smear in electronic images utilizes estimated smear signals to remove components in the image signals of the electronic images that are attributable to the smear. The estimated smear signals correspond to the smear components of the image signals. The estimated smear signals are generated by collecting electrical charges in an electronic image sensor after an exposure period. The estimated smear signals may be generated in sequence to the acquisition of the image signals. Alternatively, the estimated smear signals may be generated in parallel to the acquisition of the image signals.

    摘要: To eliminate a residual image due to residual charge in an image sensor circuit and provide an effective bright-time output, the image sensor is provided with a reset switch connected to a photodiode. After the potential of the photodiode is held through a first amplifier in two holding circuits as an image signal and an initial signal, the initial signal and the image signal are sequentially output through a second amplifier. By resetting the photodiode to a desired potential to produce an initial signal, a residual image can be eliminated.

    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.
