Glossary Number of dots in each resolution If you select WUXGA (1920 dots x 1200 dots) as the display resolution for the connecting computer, this projector can project high-resolution images. If your computer does not have the WUXGA option, select the maximum resolution among the selectable options. Progressive (P81) An image display system used to display the entire screen per scan. For an interlace signal (video signal) that displays one screen by two scans (one for odd lines and one for even lines) is input, progressive processing is required. When the progressive function is turned off, one screen is displayed using image signals per interlace signal, deteriorating the vertical resolution of the image. When the progressive function is turned on, one screen is displayed using image signals per two interlace signals, improving the vertical resolution of the image. Turn off the progressive function when flickering and horizontal lines are noticeable on a fastmoving picture. Offset (P89) A parameter that shifts the reproduction range of a brightness signal from black to white within an image signal toward the higher or lower level of brightness. The reproducibility of the dark tone is mainly changed. Since you can adjust the offset for each RGB color in this projector, you can also adjust colors. The offset is normally adjusted with the gain. Color temperature (P89) A value that represents the related color in a light source in general. In this projector, the color temperature is used to adjust the RGB color balance for the projected image to correct the related color influence by the ambient light. If you increase and decrease the color temperature, white changes to blue and red, respectively. You can set the color temperature in the [Color adjustment] menu if [Photo] has been selected for [Image mode]. Ambient light (P92) Lightning environment around the projector. You can correct and project an image more appropriately according to the ambient light on the screen via the setting of [Ambient light] if you have selected [Photo] for [Image mode]. Gamma Correction (P88, P91) A tone adjustment system used during projection of image data. The gamma correction function works effectively when portions of an image are obscure because they are too light or dark. This projector supports manual gamma correction and dynamic gamma correction which performs the gamma correction automatically. 134
