  • Patent number: 11671725
    Abstract: An image sensing device includes first and anterior comparators and first and second posterior comparators. The first anterior comparator generates a first anterior comparison signal based on a first pixel signal and a ramp signal. The first posterior comparator performs a first comparison that compares the first anterior comparison signal with a first reference signal under a first comparison precondition and generates a first posterior comparison signal corresponding to a result of the first comparison. The second anterior comparator generates a second anterior comparison signal based on a second pixel signal and the ramp signal. The second posterior comparator performs a second comparison that compares the second anterior comparison signal with a second reference signal under a second comparison precondition different from the first comparison precondition. The second posterior comparator generates a second posterior comparison signal corresponding to a result of the second comparison.
