Imaging device, image signal processing method, and program

摘要

There is provided an imaging device including a recorded image signal exposure information corrector that, on the basis of information related to different exposure times, corrects a recorded image signal recorded with the different exposure times, a mixing coefficient calculator that calculates a mixing coefficient used for mixing the corrected recorded image signal with a mixed image signal, in which recorded image signals recorded with the different exposure times are mixed, retrieved from a storage unit that saves the mixed image signal, and a mixer that outputs the mixed image signal in which the mixed image signal retrieved from the storage unit and the corrected recorded image signal are mixed on the basis of the mixing coefficients, and writes the mixed image signal to the storage unit.

1. An imaging device comprising:
one or more processors configured to: correct a recorded image signal recorded with different exposure times on the basis of information related to the different exposure times; calculate a mixing coefficient used for mixing the corrected recorded image signal with a mixed image signal; mix a first recorded image signal recorded with a first exposure time and a second recorded image signal recorded with a second exposure time on the basis of the mixing coefficient between a first threshold value of intensity of light incident on an imaging sensor and a second threshold value of the intensity of light incident on the imaging sensor; and output the mixed image signal of the first recorded image signal and the second recorded image signal, and write the mixed image signal to a storage unit.
