Abstract: A portion of a video signal for emitting light is detected, and the display brightness of the light emission portion is enhanced and displayed in a more conspicuous manner, whereby the sense of radiance is increased and the image quality is improved. A light emission detector (2) of the video display device generates a histogram in which the number of pixels is integrated into a predetermined feature quantity of an input video signal; and detects an upper region of a predetermined range of the histogram as a light emission section. An area-active control/brightness stretch portion (4) stretches and boosts the brightness of a backlight portion (6). A mapping portion (3) reduces the brightness of the video signal in a non-light-emission section, which excludes the detected light emission section. An increase in the screen brightness of the non-light-emission section is thereby suppressed, and the display brightness of the light emission section is enhanced.

Abstract: A controller in the example of this invention operates to perform flushing by ejecting three types in size of ink droplets, i.e., smaller, middle and larger ink droplets, from each of nozzles. Then the controller operates an ink-droplet detector to perform an ejection test to detect ejection conditions. Thereafter, the controller operates an ink supply section to perform cleaning in accordance with results of the test.

As a result, time for cleaning the nozzle can be suppressed. This leads to a decreased proportion of maintenance to a starting time in an apparatus and increased availability of the apparatus.
