As used herein, a subsampler in a filtering and sub sampling mechanism (104-H or 104-V) may be configured to preserve the high spatial frequency content in the direction perpendicular to the direction in which the high spatial frequency content has been filtered/removed. For example, a subsampler in the filtering and subsampling mechanism (104-H) may be configured to subsample (e.g., keep every other column) along the same horizontal direction in which the high spatial frequency content has been removed and to avoid subsampling along the vertical direction. Similarly, a subsampler in the filtering and subsampling mechanism (104-V) may be configured to subsample (e.g., keep every other row) along the same vertical direction in which the high spatial frequency content has been removed and to avoid subsampling along the vertical direction.
A multiplexed 3D image frame (one of 108-H and 108-V) comprises both a (e.g., down-sampled) image data portion for the left eye and a (e.g., down-sampled) image data portion for the right eye. The multiplexed 3D image frame may be decoded by a downstream device into a LE image frame and a RE image frame of reduced resolutions (e.g., half resolutions) in one of the horizontal and vertical directions. Such decoded LE and RE image frames of the reduced resolution may be up-sampled to comprise the same number of pixels as a full resolution image frame with a fuzzier look than a full resolution image not obtained by an up-sampling operation.
