Abstract
An image sensing device includes a counter configured to generate first count data by counting pulses corresponding to photocharges, a shift register configured to store second count data corresponding to upper digits of the first count data, and an adder configured to sum the second count data and an overflow value indicating whether the first count data has overflowed.
Claims20
An image sensing device comprising:
- a counter configured to generate first count data by counting pulses generated by detection of photocharges;
- a shift register configured to store second count data corresponding to upper digits of the first count data;
- and
- an adder configured to sum the second count data and an overflow value indicating whether the first count data has overflowed.

An image sensing device comprising:
- a counter configured to generate first count data by counting pulses corresponding to photocharges;
- and
- an adder configured to generate an overflow value indicating whether the first count data has overflowed, and configured to add the overflow value to second count data corresponding to upper digits of the first count data.
An image sensing device comprising:
- a counter configured to generate first count data by counting pulses corresponding to photocharges;
- and
- a shift register configured to store second count data corresponding to upper digits of the first count data, configured to receive the first count data after outputting the second count data, and configured to output the received first count data,
- wherein the second count data refers to data to which an overflow value indicating whether the first count data has overflowed is added.
