Abstract
There are provided a signal processing device, an imaging apparatus, a parameter generating method, a signal processing method, and a program that enable desired frequency component adjustment without complicating the processing. An image processing unit 35 includes a signal processing section that adjusts a signal according to a frequency and a filter processing control section 37 (automatic strength adjustment section 52) that controls the signal processing section. The signal processing section includes a first filter processing section 38 that performs first filter processing and a second filter processing section 39 that performs second filter processing. The automatic strength adjustment section 52 acquires the adjustment magnification (first gain adjustment magnification U and second gain adjustment magnification V) in one of the first filter processing and the second filter processing, and calculates the adjustment magnification in the other processing based on a total gain adjustment rate D.
