Abstract: The present technology relates to a signal processing device, an imaging device, and a signal processing method which are capable of recognizing a blinking target object reliably and recognizing an obstacle accurately, in a situation in which a luminance difference is very large. Signals of a plurality of images captured at different exposure times are added using different saturation signal amounts, and signals of a plurality of images obtained as a result of the addition are synthesized, and thus it is possible to recognize a blinking target object reliably and recognize an obstacle accurately, in a situation in which a luminance difference is very large. The present technology can be applied to, for example, a camera unit or the like that captures an image.

Abstract: The present technology relates to a signal processing apparatus, an imaging apparatus, and a signal processing method capable of reliably imaging a blinking imaging target in a scene having a very large difference in brightness. By detecting a difference between a plurality of images captured with different exposure times, calculating a combination coefficient indicating a combination ratio between the plurality of images on the basis of the difference, and combining the plurality of images on the basis of the combination coefficient, it is possible to reliably image a blinking imaging target in a scene having a very large difference in brightness. The present technology can be applied to, for example, a camera unit that captures an image.
