1. An image zooming apparatus comprising: a first lens having a first modulation transfer function (MTF) curve; a second lens having a second MTF curve that is different from the first MTF curve; and an imaging processor configured to obtain a first image from the first lens and a second image from the second lens, determine a region of interest (ROI) from the first image and a corresponding region from the second image, and generate a composite image by combining the first image and the second image, wherein the ROI and the corresponding region represent an identical object.
