The present technology relates to a signal processing apparatus, a signal processing method, and a display apparatus that allow moving image blur to be more appropriately removed. Moving image blur can be removed by providing a detector detecting a moving image blur video including a video in which moving image blur is easily visible, from videos included in a video content on a basis of a feature amount of the video content. The present technology can be applied to, for example, a signal processing apparatus mounted in a display apparatus such as a liquid crystal display section or a self-luminous display apparatus.
