Signal processing apparatus and method for generating a corrected image having a large number of pixels from an image having a lesser number of pixels, and recording medium having a program recorded thereon for performing such method

摘要

A signal processing apparatus includes a generator operable to generate a second image signal by converting a first image signal into the second image signal; a calculation unit operable to calculate a correction amount based on an evaluation of the second image signal relative to the first image signal; and a correction unit operable to correct the second image signal based on the correction amount.
