Abstract
A solid-state image sensing device reads repeatedly M times an analog signal having a black level, during a first A/D conversion period. A frequency divider frequency-divides by M a pulse train depending on the analog signal having a black level that is read repeatedly M times, and a counter circuit counts the pulses of the pulse train, which is frequency-divided by M. Thereafter, the solid-state image sensing device reads repeatedly N times an analog signal having a signal level, during a second A/D conversion period. The frequency divider frequency-divides by N a pulse train depending on the analog signal having a signal level that is read repeatedly N times, and the counter circuit counts the pulses of the pulse train, which is frequency-divided by N. M and N satisfy the relationship N≦M.
