Abstract
According to one embodiment, a discrimination module that discriminates whether an input image signal is of CG images or natural images, a color correction module that applies color correction processing for CG images to the input image signal when the input image signal is determined to be of CG images or applies color correction processing for natural images to the input image signal when the input image signal is determined to be of natural images, and a projection module that generates an optical image based on the image signal applied with the color correction processing, and projects and displays the image on a screen through a projection lens, are included.
Claims12
A projection display device, comprising:
- an input module that receives input of an image signal;
- a discrimination module which discriminates whether the image signal input to the input module is of CG images or of natural images;
- a color correction module which applies color correction processing for CG images to the image signal input to the input module when the discrimination module determines the image signal is of CG images, or applies color correction processing for natural images to the image signal input to the input module when the discrimination modules determines the image signal is of natural images;
- and
- a projection module which generates an optical image based on the image signal applied with the color correction processing by the color correction module, and projects and displays the image on a screen through a projection lens.
A projection display device, comprising:
- an input module which receives input of an image signal;
- a discrimination module which discriminates whether the image signal input to the input module is of CG images or of natural images;
- a color correction module which applies color correction processing for CG images to the image signal input to the input module when the discrimination module determines the image signal is of CG images, or applies color correction processing for natural images to the image signal input to the input module when the discrimination modules determines the image signal is of natural images;
- a luminous correction module which applies luminous correction processing for CG images to the image signal input to the input module when the discrimination module determines that the image signal is of CG images, or applies luminous correction processing for natural images to the image signal input to the input module when the discrimination module determines that the image signal is of natural images;
- and
- a projection module which generates an optical image based on the image signal applied with the color correction processing and the luminous correction processing by the color correction module and the luminous correction module, and projects and displays the image on a screen through a projection lens.
A control method of a projection display device, comprising:
- inputting an image signal;
- discriminating whether the input image signal is of CG images or natural images;
