  • Patent number: 9075296
    Abstract: A projection display device includes an optical modulation element configured to modulate light outputting from a light source, and a projection unit configured to project light modulated by the optical modulation element on a projection screen. The projection display device includes an element control unit that controls the optical modulation element to display a test pattern image, an acquiring unit that acquires an image obtained by capturing the test pattern image from an image capture element that captures the test pattern image projected on the projection screen, and an adjusting unit that adjusts an image projected on the projection screen on the basis of the capture image acquired by the acquiring unit. The element control unit controls the optical modulation element such that a guidance image that guides focus adjustment of the image projected on the projection screen is displayed.

  • Publication number: 20150019142
    Abstract: A first measured value of a specific physical quantity at a target portion is correlated with a damage evaluation index to calculate a damage degree corresponding to the first measured value. The specific physical quantity is measured at least once at a position corresponding to the first measurement position in another time period having a different usage elapsed time from that of the first measurement, and these second and subsequent measured values are correlated with damage degrees calculated based on temporal changes corresponding to the second and subsequent measurements. A new damage evaluation index is approximately calculated based on a relationship between the first, second, and subsequent measured values and the damage degrees corresponding to the first, second, and subsequent measured values.
