Abstract:
1. A solid-state imaging device comprising: a solid-state imaging element for outputting two image signals which are different from each other in an exposure amount and the number of pixels; interpolation means for converting an image signal having a small number of pixels of said two image signals having a different number of pixels, into an image signal having the same signal type as an image signal having a large number of pixels by an interpolation process; and signal synthesizer means for synthesizing said image signal having a large number of pixels and said image signal converted into the same signal type as said image signal having a large number of pixels by said interpolation means according to a synthesis control signal, said synthesis control signal being at least one of said image signal having a small number of pixels, said image signal converted into the same signal type as said image signal having a large number of pixels by said interpolation means, and said image signal having a large number of pixels, wherein the signal synthesizer means includes: coefficient generation means for generating a certain coefficient k according to a signal level of said synthesis control signal, and synthesizer means for weighting and adding said image signal having a large number of pixels and said image signal converted into the same signal type as said image signal having a large number of pixels by said interpolation means according to the coefficient k generated by said coefficient generation means.
