VIDEO REPRODUCING DEVICE EQUIPPED WITH REGULATION FUNCTION FOR SUB PICTURE

PROBLEM TO BE SOLVED: To provide a video reproducing device capable of changing luminance and color difference for a sub picture such as a title so as to make the sub picture easy to be read according to surrounding brightness. SOLUTION: A data read-out portion 4 reads video data, audio data, and sub picture data from a record medium 2. A decoder processing portion 5 separates them into video data, audio data, and sub picture data. A level of intensity around a DVD player 1 is computed based on a detected signal from a photosensor 8, and compared with a threshold used as a reference and established beforehand to output to a sub picture data transformation portion 7. The sub picture data transformation portion 7 changes the luminance and color difference of the sub picture data according to the level of intensity computed by a intensity detection portion 13, and outputs it to a reproduced picture output portion 6. The changed sub picture and the video image are superimposed and displayed on a display 3. COPYRIGHT: (C)2006,JPO&NCIPI
