    • A projection apparatus (10) has an illumination section with a light source (20) providing a substantially unpolarized illumination beam of multiple wavelengths. A multiple wavelength polarizer polarizes the substantially unpolarized illumination beam to provide a substantially polarized illumination beam of multiple wavelengths. A uniformizer conditions the substantially polarized illumination beam of multiple wavelengths to provide a uniformized polarized beam of multiple wavelengths. A color scrolling element provides a repeating, scrolled sequence of colors from a set of colors, thereby providing first, second, and third component wavelength illumination. A component wavelength modulating section accepts the sequence of first, second, and third component wavelength illumination from the color scrolling element and sequentially modulates the first, second, and third component wavelength illumination at a transmissive liquid crystal modulator panel (118) to provide a modulated component wavelength beam to a lens for projection toward a display surface (40).

    • A method for monitoring and adjusting the calibration for an image processing apparatus entails imaging a calibration target to create an image using the image processing apparatus and scanning the image into host software to create an exposure calibration curve. Control strips are imaged to create control strip images on order to obtain a calibrated density history for the control strips using the control strip images. The control strip images are scanned into the host software to obtain a scanned density history for each control strip and thereby form a density history for the control strips. A deviation history is calculated by comparing the scanned density history to the calibrated density history for each control strip. The deviation history is monitored to ensure that the deviation history is within the operating specifications for the image processing apparatus.
    • 用于监视和调整图像处理装置的校准的方法需要使用图像处理装置对校准目标进行成像以创建图像,并将图像扫描到主机软件中以产生曝光校准曲线。 控制条被成像以产生控制条图像,以便使用控制条图像获得控制条的校准密度历史。 将控制条图像扫描到主机软件中以获得每个控制条的扫描密度历史,从而形成控制条的密度历史。 通过将扫描密度历史与每个控制条的校准密度历史进行比较来计算偏差历史。 监视偏差历史以确保偏差历史在图像处理装置的操作规范内。
