Abstract
In the case of performing focus adjustment, image quality control is performed to set to relatively a high-contrast sense color mode of plural color modes that enable to set according to an environment at the time of projection.
Claims12
A projection-type display device comprising:
- an image projection unit which projects an image;
- an image quality adjustment unit which adjusts an image quality of the image to a color mode included in a plurality of color modes enabled to be set according to an environment at the time of projection;
- a focus adjustment unit which performs focus adjustment of the image;
- and
- a control unit which
- when performing the focus adjustment of the image, performs image quality control to set the image quality of the image projected by the image projection unit to a relatively high-contrast sense color mode included in the plurality of color modes, and
- performs image quality control to restore the image quality of the image to the color mode immediately preceding the performing of the focus adjustment of the image,
- wherein each of the plurality of color modes includes data describing a value of each of a plurality of image quality parameters, the plurality of image quality parameters comprising brightness, contrast, and sharpness, and
- wherein the relatively high-contrast sense color mode comprises a color mode included in the plurality of color modes having a value of at least one of the plurality of image quality parameters that is higher than a value of the at least one of the image quality parameters of at least one of the other color modes included in the plurality of color modes.
A control method for a projection-type display device including an image projection unit which projects an image, an image quality adjustment unit which adjusts an image quality of the image to a color mode included in a plurality of color modes enabled to be set according to an environment at the time of projection, each of the plurality of color modes including data describing a value of each of a plurality of image quality parameters, and a focus adjustment unit which performs focus adjustment of the image, comprising the steps of:
- projecting the image by the image projection unit,
- performing focus adjustment of the image,
- when performing the focus adjustment of the image, performing image quality control to set the image quality of the image to a relatively high-contrast sense color mode included in the plurality of color modes, and
- performing image quality control to restore the image quality of the image to the color mode immediately preceding the performing of the focus adjustment of the image,
- wherein the relatively high-contrast sense color mode comprises a color mode included in the plurality of color modes having a value of at least one of the plurality of image quality parameters that is higher than a value of the at least one of the image quality parameters of at least another color mode included in the plurality of color modes.
