<p>A video with a display definition most suitable for the type of the video content to be displayed can be displayed. A liquid crystal display apparatus controls the luminance of the backlight light source according to the APL of the video signal measured by an APL measuring portion (16). The range of the video signal the APL of which is measured can be determined by, e.g. , the luminance level of the video signal or by the genre information included in the inputted video signal or the OSD display information used when the liquid crystal apparatus (1) performs OSD display. The drawing shows the state that the upper and lower non-video areas are removed and an effective video area is determined. With this, the additional information displayed when the video signal is of a specific genre and the OSD-displayed additional information can be excluded, and the luminance of the backlight light source can be controlled to realize a display definition most suitable for the video signal.</p> |
