Abstract:
1. A sensing device, comprising: an array of active pixel sensors, including a first sub-array and a second sub-array; a first set of sampling circuits connected to the first sub-array for sampling the first sub-array to generate a first set of analog signals; a second set of sampling circuits connected to the second sub-array for sampling the second sub-array to generate a second set of analog signals; and a readout circuit connected to both of the two sets of sampling circuits for sequentially reading the first set of analog signals and the second set of analog signals and performing analog to digital conversion to generate a plurality of digital signals; wherein the second set of sampling circuits samples the second sub-array while the readout circuit reads the first set of analog signals and performs the analog to digital conversion, and wherein the first set of sampling circuits samples the first sub-array while the readout circuit reads the second set of analog signals and performs the analog to digital conversion; wherein the first sub-array comprises a plurality of first rows and one of the first rows is adjacent to another of the first rows in a first direction; wherein the second sub-array comprises a plurality of second rows and one of the second rows is adjacent to another of the second rows in the first direction; and wherein the first sub-array is disposed adjacent to the second sub-array in a second direction which is different from the first direction.
