RESOLUTION CONVERSION APPARATUS AND RESOLUTION CONVERSION METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To suppress deterioration in image quality while reducing a memory capacity. <P>SOLUTION: A resolution conversion circuit 200 comprises: line buffers 202 and 203 for storing inputted image data; and a three-pixel convolution operation circuit 208 which, when generating a vertical interpolation pixel Po by referring to three pixels containing pixel data stored in the line buffers 202 and 203, switches between interpolation by referring to two upper pixels P<SB POS="POST">i1</SB>and P<SB POS="POST">i2</SB>and one lower pixel P<SB POS="POST">i3</SB>of the interpolation pixel Po and interpolation by referring to one upper pixel P<SB POS="POST">i2</SB>and two lower pixels P<SB POS="POST">i3</SB>and P<SB POS="POST">i4</SB>of the interpolation pixel Po. <P>COPYRIGHT: (C)2013,JPO&INPIT |
