Abstract
There is provided a signal processing device, a signal processing method, and a detection sensor that makes it possible to detect flicker information from an output indicating a luminance change. The signal processing device includes: a change detection unit that detects a first luminance change in a positive direction and a second luminance change in a negative direction among luminance changes detected by a light receiving unit; a coefficient generation unit that generates a coefficient depending on a time at which the luminance change is detected; and an integration unit that integrates a result of multiplication of the first luminance change and the coefficient and integrates a result of multiplication of the second luminance change and the coefficient. The present technology can be applied to, for example, an event detection sensor and the like.
