Abstract: A method includes generating a pattern, and projecting the pattern. A plurality of elements are arranged in the pattern. The method further includes selecting a color for each of the plurality of elements from a color candidate group including a plurality of colors with equal differences between the plurality of colors. The color of each of the plurality of elements is different from a neighboring color of a neighboring element adjacent to that element. A plurality of color sequences corresponding to a plurality of sub-arrays are different from each other. The plurality of sub-arrays includes at least one element from among the plurality of elements. Distances between pairs of color sequences of the plurality of color sequences within the pattern are greater than or equal to a predetermined threshold.

Abstract: A projecting device includes a light source configured to output an image light; a projection lens configured to externally project the image light; a camera configured to photograph an object positioned between the camera and an external projection surface of the image light that is projected; a light blocker configured to block the image light output by the light source during a blocking period; and at least one processor configured to: obtain illuminance information regarding illuminance of the external projection surface, set the blocking period during which the image light output by the light source is blocked, based on the illuminance information, set a photographing period within the blocking period, control the light blocker to block the image light output by the light source during the blocking period, and control the camera to photograph the object during the photographing period.

Abstract: A projector includes a monochromatic self-luminous display panel; a color filter disposed in front of the monochromatic self-luminous display panel; a filter driver configured to move the color filter in direction parallel to the monochromatic self-luminous display panel; a micro lens array disposed in front of or behind the color filter and configured to convert light emitted from the monochromatic self-luminous display panel into parallel light; a projection lens disposed in front of the micro lens array and the color filter and configured to project light that has passed through the micro lens array and the color filter onto a screen; and a processor configured to control the monochromatic self-luminous display panel and the filter driver.
