Patent ID: 7986858

Claim:
An image enlarging apparatus comprising: a luminance data calculation unit configured to set a reference frame from a video image which has a plurality of pixels, and to calculate first luminance data for a high resolution video image, the high resolution video image obtained by interpolating supplementary luminance data into the reference frame having second luminance data, the number of pixels of the high resolution video image being larger than the video image; a position calculation unit configured to set target pixels in at least one of frames included in the video image except the reference frame, and to calculate corresponding positions to the target pixels in the reference frame with decimal accuracy; a correction amount calculation unit configured to calculate correction amounts of the first luminance data for the corresponding positions based on the first luminance data, third luminance data of the target pixels, and the corresponding positions, the correction amounts being parallelly calculated for the respective corresponding positions; an addition unit configured to calculate sum of correction amounts from the correction amounts; and a luminance data correction unit configured to correct the first luminance data based on the sum of the correction amounts.
