SIGNAL PROCESSING DEVICE, IMAGING APPARATUS, PARAMETER GENERATING METHOD, SIGNAL PROCESSING METHOD, AND PROGRAM

摘要

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.

主权项

1. A signal processing device, comprising:
a signal processing unit that adjusts a signal according to a frequency; and a filter processing control unit that controls the signal processing unit, wherein the signal processing unit includes a first filter processing section that performs first filter processing and a second filter processing section that performs second filter processing having different frequency characteristics from the first filter processing, and the filter processing control unit acquires a total gain adjustment rate based on an adjustment magnification of a gain of the signal in the first filter processing and an adjustment magnification of a gain of the signal in the second filter processing, acquires the adjustment magnification in one of the first filter processing and the second filter processing, and calculates the adjustment magnification in the other one of the first filter processing and the second filter processing based on the total gain adjustment rate.
