Abstract:
An apparatus for resizing and converting frame rate of a sequence of images, comprising:a buffer for receiving pixel data of a sequence of input images having a first temporal resolution, wherein the buffer stores both odd and even lines of at least one of the input images, wherein the odd and even lines are temporally coherent; and a resizer for resizing each of the received input images to produce an output image using both odd and even lines from the input image, and for accessing the buffer to perform resizing operations having parameters defined at a second temporal resolution different from the first resolution, wherein the resizer has an output for providing a sequence of the output images at the second temporal resolution; wherein the parameters include a kind of field to be output according to a pulldown sequence and an area in the input image from which both odd and even lines of the input image are sampled to create the output image.
