Projection display apparatus, display for same and image display apparatus

A projection display apparatus that projects images onto a screen, comprising:

• a frame memory for storing given original image data;
• a first embellishment memory for storing a first embellishment image data representing a first embellishment image having a shape and size that can be set;
• a second embellishment memory for storing a second embellishment image data representing a second embellishment image having a size that can be altered while a shape is maintained similar;
• an image embellishment section that generates embellished image data representing embellished image by overlaying an original image represented by the original image data with at least one of the first embellishment image and the second embellishment image;
• an image display signal generator for generating image display signals based on the embellished image data;
• an electro-optical device for emitting light that forms images in response to the image display signals;
• and
• a projection optical system for projecting light emitted by the electro-optical device.

An image display apparatus, comprising:

• a frame memory for storing given original image data;
• a first embellishment memory for storing a first embellishment image data representing a first embellishment image having a shape and size that can be set;
• a second embellishment memory for storing a second embellishment image data representing a second embellishment image having a size that can be altered while a shape is maintained similar;
• an image embellishment section that generates embellished image data by overlaying an original image represented by the original image data with at least one of the first embellishment image and the second embellishment image;
• an image display signal generator for generating image display signals based on the embellished image data;
• and
• an electro-optical device for emitting light that forms images in response to the image display signals.

A method of displaying images using a projection display apparatus having a light modulation unit to display an image based on image data given to the projection display apparatus by projecting the image onto a screen, comprising the steps of:

• preparing embellishment effect data representing an embellishment effect image that is used to embellish an arbitrary image;
• generating embellished image data representing embellished image by overlaying an original image represented by the given image data and the embellishment effect image;
• driving the light modulation unit in response to the embellished image data pixel by pixel;
• and
• projecting onto the screen the embellished image obtained by the light modulation unit.

A method of displaying an image obtained by embellishment of original image data given to a projection display apparatus, comprising the steps of:

• storing given original image data;
• storing a first embellishment image data representing a first embellishment image having a shape and size that can be set;
• storing a second embellishment image data representing a second embellishment image having a size that can be altered while a shape is maintained similar;
• and
• generating embellished image data representing embellished image by overlaying an original image represented by the original image data with at least one of the first embellishment image and the second embellishment image.

A display control method of a projection display apparatus that displays embellishment image overlaid on a given original image, comprising the steps of:

• using a remote controller so as to display a menu screen overlay;
• using the remote controller so as to select from the menu a desired embellishment image among a plurality of embellishment images and an embellishment image display condition such as color;
• erasing the menu screen and displaying an overlay of the selected embellishment image and a display pointer image symbolizing the display condition;
• using the remote controller so as to move the display pointer image and display an overlay of a starting pointer image at a starting position determined for the embellishment image;
• and
• using the remote controller to again move the display pointer image and determine an end position of the embellishment image to display an overlay of the embellishment image between the starting position and the end position determined for the embellishment image.
