    摘要： A projecting system includes an image projector that includes an optical source and that projects an image on a projected surface; and a processor. The processor obtains brightness information regarding brightness around the projected surface. The processor selects at least one item among a total luminous flux of the optical source, a color gamut of the image, and a size of the image. The processor adjusts the item that is selected based on the brightness information.

    摘要： An image processing method comprising displaying a first image; displaying a first correction point, with which first brightness is associated, at a first position in the first image; moving the first correction point from the first position to a second position along a first axis of the first image; and generating a second image that has the first brightness in a first range including a position corresponding to the second position and intersecting with the first axis.

    摘要： A projection system and method therefore related to a first projection device; a second projection device; at least one spatial modulator; and an electronic processor configured to: receive a two-dimensional video data, generate a first plurality of intensity values of a first color gamut and a second plurality of intensity values of a second color gamut, subtract a luminance threshold from a plurality of pixel values of the second color gamut to yield a plurality of positive pixel values and a plurality of negative pixel values, set respective ones of the plurality of pixel values to predetermined values to obtain a residual of the second color gamut, add the residual to the first color gamut, add maximized pixel values to the first color gamut and the second color gamut to create an output gamut, and blend the output gamut with a native color gamut to generate a blended gamut.

    摘要： A control section of a first projector performs automatic color adjustment that determines, based on the result of capture of a first image projected by the first projector and a second image projected by a second projector, a first correction value used to correct the color of the first image, performs manual color adjustment that accepts the operation of correcting the color of a third image produced by correcting the first image with the first correction value and projected by the first projector and determines, based on the result of the operation, a second correction value used to correct the color of the third image, updates the first correction value by performing the automatic color adjustment again when a setting condition set in advance is satisfied, and outputs the first correction value updated by performing the automatic color adjustment again and the second correction value.

    摘要： A chromaticity adjusting method of a projector includes a first light source for emitting blue light and a second light source for emitting yellow light including red light and green light. A chromaticity value of the blue light is acquired and the chromaticity value and the luminance value of each of the red light and the green light is obtained. The second target chromaticity value is determined based on the first target chromaticity value, the chromaticity value of the blue light, and the chromaticity value and the luminance value of each of the red light and the green light. Light quantities of the first and second light sources are controlled based on the second target chromaticity value. Signal levels of the red, green, and blue color components included in the video signal are controlled according to the difference between the first target chromaticity value and the second target chromaticity value.

    摘要： A projection device and a projecting method are provided. The projection device includes a controller, a light engine, and a storage device. The storage device stores gamma correction curves and a predetermined amount. The controller receives display information of an image. The display information includes pixel information. The controller is configured to: set gray level regions and determine which gray level region does each pixel information fall into according to a gray level of the pixel information; calculate a pixel amount of the pixel information fallen into each gray level region; and when one of the pixel amount exceeds the predetermined amount, select a selected gamma correction curve from the gamma correction curves and adjust the display information according to the selected gamma correction curve to generate adjusted display information. The light engine is electrically coupled to the controller, receives the adjusted display information, and projects an adjusted image accordingly.
