1. A signal processing device comprising:
an afterimage analyzer to calculate image accumulation information based on an input image;
an afterimage learning processor to perform learning based on the image accumulation information and adjust an afterimage reducing strength based on the learning; and
an afterimage reducing processor to perform an afterimage reducing process based on the afterimage reducing strength from the afterimage learning processor,
wherein the afterimage learning processor is configured to store the image accumulation information or the afterimage reducing strength in an external nonvolatile memory,
wherein in response to power being turned on, the afterimage learning processor is configured to receive the image accumulation information or the afterimage reducing strength from the external nonvolatile memory, and
wherein in response to the power being turned off, the afterimage learning processor is configured to transmit the image accumulation information or the afterimage reducing strength to the external nonvolatile memory.
