Abstract
The technique of the present invention carries out specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of an image projected by a projector. A typical example of such image processing is sharpness adjustment. The degree of emphasis in sharpness adjustment at each site is specified, based on an elevation angle of the projector and a focalized position of the projected image. The technique of the invention thus readily prevents deterioration of the image quality due to out-of-focus state of the projected image.
Claims10
An image processing apparatus that carries out a predetermined series of image processing with regard to original image data, so as to generate processed image data, which is supplied to a projector that projects a resulting image, said image processing apparatus comprising:
- an original image data input module that receives input of original image data;
- and
- an image processing module that makes the original image data subjected to specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of the projected image,
- wherein the degree of emphasis is varied depending upon a distance from a reference point set relative to the projected image.
A projector that projects an image, comprising:
- an image processing module that carries out a predetermined series of image processing with regard to input original image data, so as to generate processed image data;
- an image generation module that generates an image to be projected, based on the processed image data;
- and
- a projection optical system that projects the image,
- wherein said image processing module makes the original image data subjected to specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of the projected image,
- wherein the degree of emphasis is varied depending upon a distance from a reference point set relative to the projected image.
An image processing method that carries out a predetermined series of image processing with regard to original image data, so as to generate processed image data, which is supplied to a projector that projects a resulting image, said image processing method comprising the steps of:
- (a) receiving input of original image data;
- and
- (b) making the original image data subjected to specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of the projected image,
- wherein the degree of emphasis is varied depending upon a distance from a reference point set relative to the projected image.
A recording medium in which a computer program is recorded in a computer readable manner, said computer program carrying out a predetermined series of image processing with regard to original image data, so as to generate processed image data, which is supplied to a projector that projects a resulting image, said computer program causing a computer to attain the functions of:
- receiving input of original image data;
- and
- making the original image data subjected to specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of the projected image,
- wherein the degree of emphasis is varied depending upon a distance from a reference point set relative to the projected image.
