Image signal processing apparatus, image signal processing method, and image projection apparatus
First Claim
1. An image signal processing apparatus comprising:
- a first conversion processing unit configured to perform conversion processing for a left-eye image signal used to display a left-eye image on a curved screen so as to adjust a horizontal and/or vertical size of the left-eye image and to correct a vertical bow-like distortion of the left-eye image other than displacement occurring due to horizontal shifting and vertical shifting;
a second conversion processing unit configured to perform conversion processing for a right-eye image signal used to display a right-eye image on the curved screen so as to adjust a horizontal and/or vertical size of the right-eye image and to correct a vertical bow-like distortion of the right-eye image other than displacement occurring due to horizontal shifting and vertical shifting; and
a merging unit configured to obtain an output image signal by merging a left-eye image signal obtained by performing the conversion processing through the first conversion processing unit and a right-eye image signal obtained by performing the conversion processing through the second conversion processing unit.

8. An image signal processing method comprising the steps of:
-
performing first conversion processing for a left-eye image signal used to display a left-eye image on a curved screen so as to adjust a horizontal and/or vertical size of the left-eye image and to correct a vertical bow-like distortion of the left-eye image other than displacement occurring due to horizontal shifting and vertical shifting; performing second conversion processing for a right-eye image signal used to display a right-eye image on the curved screen so as to adjust a horizontal and/or vertical size of the right-eye image and to correct a vertical how-like distortion of the right-eye image other than displacement occurring due to horizontal shifting and vertical shifting; and obtaining an output image signal by merging a left-eye image signal obtained by performing the first conversion processing and a right-eye image signal obtained by performing the second conversion processing.

9. An image projection apparatus comprising:
-
an image display unit configured to align a left-eye image and a right-eye image, in a vertical direction, on a display panel for display; and a projection optical system configured to downwardly project the left-eye image and the right-eye image that are displayed on the display panel onto a screen so that the left-eye image and the right-eye image on the display panel are superimposed on each other on the screen, wherein the image display unit includes a first conversion processing unit configured to perform conversion processing for a left-eye image signal used to display the left-eye image so as to adjust a horizontal and/or vertical size of the left-eye image and to correct a vertical bow-like distortion of the left-eye image other than displacement occurring due to horizontal shifting and vertical shifting, a second conversion processing unit configured to perform conversion processing for a right-eye image signal used to display the right-eye image so as to adjust a horizontal and/or vertical size of the right-eye image and to correct a vertical bow-like distortion of the right-eye image other than displacement occurring due to horizontal shifting and vertical shifting, and a merging unit configured to obtain an output image signal by merging a left-eye image signal obtained by performing the conversion processing through the first conversion processing unit and a right-eye image signal obtained by performing the conversion processing through the second conversion processing unit. - View Dependent Claims (10)
