Abstract: A text-to-speech device includes: a video data acquisition unit configured to acquire video data including a video of a region around a user; a positional information acquisition unit configured to acquire positional information indicating a position of a user; a category identification unit configured to identify a category of a location where the user is positioned, based on the acquired positional information and map information related to an area including the position of the user indicated by the positional information; a text extraction unit configured to extract text information representing text included in video data of a region around the user; a priority setting unit configured to set degrees of priority for the extracted text information; and a voice output unit configured to convert the extracted text information into voice, and outputs the voice, in descending order of the set degrees of priority.

Abstract: A uniformity correction data generation unit generates uniformity correction data for an R signal, a G signal, and a B signal. A multiplier multiplies pixel signals of the R signal, the G signal, and the B signal by the uniformity correction data for the R signal, the G signal, and the B signal. The multiplier shifts, from one another, positions of pixels at a time of multiplying the pixel signals of the R signal, the G signal, and the B signal by the uniformity correction data for the R signal, the G signal, and the B signal.
