1. An image sensing device, comprising:
an array of sensing pixels;
an output amplifier, connected to the array of sensing pixels, for amplifying a measurement signal of each sensing pixel of the array of sensing pixels;
an analog-to-digital converter (ADC), connected to the output amplifier, for converting the amplified measurement signal of each sensing pixel of the array of sensing pixels into digital data;
a first set of registers, for storing parameters to operate the image sensing device that control the output amplifier;
a second set of registers, connected to the ADC, for storing the digital data converted by the ADC;
an activation circuit, connected between the array of sensing pixels and the output amplifier, for controlling output sequence of the array of sensing pixels, including a selective activation circuit to selectively enable an output of a subset of the array of sensing pixels; and
a profiling logic, connected to the first and second sets of registers, for performing the followings:
conducting statistical analysis on output data from the subset of the array of sensing pixels;
adjusting the parameters stored in the first set of registers until results of the statistical analysis reaches a target standard;
using the adjusted parameters to generate an output image by each sensing pixel of the array of sensing pixels once the target standard is reached; and
sending a notification signal to an external device for notifying the failure of parameter adjustment if the target standard fails to be reached within predetermined times of adjustment,
wherein the activation circuit comprises a plurality of basic units, and wherein each of the plurality of basic units comprises a flip-flop and at least one multiplexer.
