An image reading apparatus which is capable of preventing images read from a double-sided original from suffering an in-surface color irregularity on each of images read from the respective opposite sides of a double-sided original and a color difference between the front and reverse. A CCD line sensor reads a front-side original image. An image processing ASIC calculates shading correction data for performing shading correction on original image data read from the original image by the CCD line sensor, based on read luminance values obtained by the CCD line sensor by reading a plurality of halftone gradation patches thereon on a correction chart. The shading correction data calculated by the image processing ASIC is corrected based on read luminance values associated, respectively, with at least two of the gradation patches.

An apparatus and a method for automatic inspection of through-holes of a component is provided. The proposed apparatus includes an imaging module, an image processing module and an analysis module. The imaging module generates a thermographic image of the component by passing a medium through the through-holes and capturing infra-red radiation emitted from the component while the medium is flowing through the through-holes.

The image processing module is further masks the fitted thermographic image using a digital image mask to extract regions corresponding to through-holes in the thermographic image. The digital image mask is computed based on a determination of positions of through-holes on the digital image. The analysis module evaluates the masked thermographic image to determine an irregularity or blockage in one or more of the through-holes.
