Abstract: PURPOSE:To display pictures with high reliability with respect to a device for displaying pictures of good quality with high image resolution by providing a  liquid layer and a heating element for generating foam in the liquid layer, connecting liquid circulating paths to the liquid layer and performing vapourization  and liquefaction in the circulating paths. CONSTITUTION:When a display element 31 is driven continuously, the temp. of a thin liquid film 32 is risen by accumulated heat and may generate vapor foam. Since the foam can be a cause for noise, the foaming is prevented by so arranging the element that the liquid of the film 32 circulates among the element 31, a vapourizing chamber 33 and a liquefying chamber 34. The chamber 33 deprives excess heat from the liquid and the evaporating rate of the liquid is increased by a pressure reducing means 35. The heat is released to the outside of the system by the chamber 33. When a laser beam is irradiated to the element  31 intermittently, and observing light 45a is irradiated to the element 31 while making images, the reflected light 45b thereof is projected on a screen. Thus, thermal noises and noises by pressure are removed and pictures are displayed with excellent drivability and reliability.

Abstract: PURPOSE:To prevent an error in recognition by detecting common sections among candidate bodies to be recognized for a reliable section to be stored in a recognition dictionary, and generating an alarm according to the detection result. CONSTITUTION:An observation part 1 observes plural candidate bodies to be recognized optically and data on them are stored in a video memory 2 and also supplied to a feature extraction part 4 through a preprocessing part 3 to extract their contours and specific geometric feature parameters. A switch part 5 switches the extracted data to the recognition dictionary 6 or a recognition part 7.

In this case, if there are common sections in the reliable section of the feature parameter, an error in recognition is easy to occur, so this is detected by a detecting circuit 8 and a warning device 9 generates an alarm. An operator evades the error in recognition by combining the candidate bodies to be recognized according to the alarm so that at least one of the common sections in the reliable section becomes zero.
