Abstract:
1. An image sensing apparatus comprising: a plurality of energy transducers; an arithmetic circuit for generating a plurality of converted signals by applying processing to signals from each of a prescribed number of neighboring ones of said energy transducers, said prescribed number of neighboring energy transducers constituting a unit block; an output circuit for outputting the converted signals generated by said arithmetic circuit; and, a plurality of A/D converters, wherein said plurality of energy transducers, said arithmetic circuit and said output circuit are formed on the same semiconductor substrate; and the plurality of converted signals generated by said arithmetic circuit include a first converted signal generated by adding signals obtained from said unit block, and a second converted signal that includes differences between signals obtained from said unit block; and wherein said A/D converters convert the first and second converted signals, which are output by said output circuit, to digital data, wherein the number of bits of digital data of the first converted signal is greater than the number of bits of digital data of the second converted signal.
