Method and device for changing image size
First Claim
Patent Images
1. A method of changing an image size, comprising:
- storing an original image that has been processed in units of unit areas which are defined by dividing one frame; and
changing a size of the original image at least in a horizontal direction by interpolating data in an interpolation pixel between predetermined pixels in each of the unit areas of the original image according to a set horizontal increasing scale factor, wherein each of the unit areas includes a plurality of first boundary pixels arranged along a vertical virtual boundary line between two of the unit areas adjacent in the horizontal direction in the frame, and wherein, in the image size changing step, the interpolation pixel is set between pixels other than the first boundary pixels.

Abstract
A method of changing an image size includes changing a size of the original image at least in a horizontal direction by interpolating data in an interpolation pixel between predetermined pixels in each of the unit areas of the original image according to a set horizontal increasing scale factor. Each of the unit areas includes a plurality of first boundary pixels arranged along a vertical virtual boundary line between two of the unit areas adjacent in the horizontal direction in the frame. In the image size changing step, the interpolation pixel is set between pixels other than the first boundary pixels.

11. A device for changing an image size, comprising:
-
a storage circuit which stores an original image that has been processed in units of unit areas which are defined by dividing one frame; and
an image size changing circuit which changes a size of the original image from the storage circuit at least in a horizontal direction by interpolating data in an interpolation pixel between predetermined pixels in each of the unit areas of the original image according to a set horizontal increasing scale factor, wherein each of the unit areas includes a plurality of first boundary pixels arranged along a vertical virtual boundary line between two of the unit areas adjacent in the horizontal direction in the frame, and wherein the image size changing circuit sets the interpolation pixel between pixels other than the first boundary pixels. - View Dependent Claims (12, 13, 14, 15, 16, 17)
