ABSTRACT:
An imaging apparatus provides minimal S/N degradation with a high resolution at low illumination. The imaging apparatus includes a CCD, a gain adjusting section, an LPF for performing smoothing on an output signal of the gain adjusting section, and a control section and a selecting section selecting for outputting either the output signal or the LPF according to a magnitude of gain of the gain adjusting section. Also included are a three-dimensional NR for performing recursive noise reduction, a detail extracting section, and an adder that enhance a two-dimensional high-frequency component of an output signal of the three-dimensional NR. The control and selecting sections perform the selection to provide the output signal of the gain adjusting section to the three-dimensional NR when the gain of the gain adjusting section is equal to or lower than a predetermined value. Otherwise, the output of the LPF is provided to the three-dimensional NR.
