Projection method and projector. Improve the detection accuracy of points included in a projected point pattern. A projector (1) projects a point pattern (210a) including a first point (231), a second point (232), a third point (233), a fourth point (234), and a black point (235) to a projection surface (7). The display modes of the first point (231), the second point (232), the third point (233), the fourth point (234), and the black point (235) are different from each other, the first point (231) is located adjacent to the second point (232) in a horizontal direction and adjacent to the third point (233) in a vertical direction, the second point (232) is located adjacent to the fourth point (234) in the vertical direction, and the third point (233) is located adjacent to the first point (231) in the horizontal direction.

The utility model relates to the field of industrial mechanical device discloses a kind of black point detection equipment for horizontal immersion drying, including horizontal device ontology, the two sides of the horizontal device ontology are respectively provided with feed inlet and discharge port, immersion interval, drying room and detection room are sequentially provided between the feed inlet and discharge port, the inside fixed connection of the immersion interval has adjusting structure, the adjusting structure includes sliding slot, the inside fixed connection of the immersion interval has threaded rod, one end of the threaded rod is fixedly connected with adjusting motor, the outside of the threaded rod is sleeved with sliding block, the bottom of the sliding block is fixedly connected with moving rod, the bottom of the moving rod is fixedly connected with moving press roll. In the utility model, adjusting motor and threaded rod are used, the horizontal position of moving press roll is adjusted by controlling the movement of sliding block, and then the immersion time of paper is controlled, the immersion time of paper of different materials is adjusted, and the compatibility and applicability of the equipment are improved.

Disclosed are dynamic system optical-to-optical transfer functions (OOTF), which adapt displayed content to provide a so-called “perceptual reference” effect for the viewer, wherein, as the current viewing conditions depart from a “reference” viewing scenario, the dynamic system OOTF adapts the content and / or display to provide the viewer with as close as possible to the perceptual effect of the “reference” viewing scenario. The dynamic system OOTF may perform one or more of the following adaptation processes: adapting media content from a source color space to a linear XYZ color space; adapting media content from a linear XYZ color space to a display device's color space; automatically adjusting display device brightness, white point, and / or black point; adapting media content from an intended viewing environment to a common compositing space's fixed viewing environment; and / or adapting media content from the common compositing space's fixed viewing environment to that of the viewer's current viewing conditions.
