Image processing apparatus, image processing method, program, and storage medium with length-to-breath image conversion and superimposing of images
First Claim
1. An image processing apparatus including a function of superposing a second image on a first image, comprising:
- a converting device which converts a length-to-breadth ratio of at least the first image;
a first superposing device which superposes the second image on the first image before the length-to-breadth ratio is converted by said converting device; and
a second superposing device which superposes the second image on the first image after the length-to-breadth ratio is converted by said converting device,wherein, when the first image converted by said converting device is to be displayed on a display device comprising a screen with a length-to-breadth ratio corresponding to the length-to-breadth ratio of the first image which is not converted by said converting device, said second superposing device superposes the second image on the first image such that the second image is displayed within an effective range of the first image displayed on the screen of said display device.

Abstract
This invention prevents quality deterioration and positional shift of OSD when an image and the OSD are to be together displayed by LB display. An image processing apparatus having a function of superposing a second image on a first image includes a converter (103) which converts the length-to-breadth ratio of at least the first image, a first superposing unit (101) which superposes the second image on the first image before the length-to-breadth ratio is converted by the converter (103), and a second superposing unit (105) which superposes the second image on the first image after the length-to-breadth ratio is converted by the converter (103).

9. An image processing method of superposing a second image on a first image, comprising:
-
a conversion step of converting a length-to-breadth ratio of at least the first image; a first superposition step of superposing the second image on the first image before the length-to-breadth ratio is converted in the conversion step; and a second superposition step of superposing the second image on the first image after the length-to-breadth ratio is converted in the conversion step, wherein, when the first image converted in the conversion step is to be displayed on a display device comprising a screen with a length-to-breadth ratio corresponding to the length-to-breadth ratio of the first image which is not converted in the conversion step, the second image is superposed on the first image in the second superposition step such that the second image is displayed within an effective range of the first image displayed on the screen of the display device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
