Enhanced imaging method and apparatus

This invention provides accurate, high quality images for the identification of the surface characteristics of an object, that may be used as an input to suitable industrial process. It involves acquiring a first raw scan of a portion of a target object across a scan line in a scan zone with a first camera and simultaneously acquiring a second raw scan of the same portion of the target object across the scan line in the scan zone with a second camera. The raw scans are converted to digital and then processed with flattening coefficients derived from measurements of variations in illumination. The first and second cameras sets of flattened image data are then gridized to compensate for parallax, make them orthographic sets of image data that can be compared on a pixel-by-pixel basis with a known or measured geometric profile of the target. A selection of enhanced pixel value for a surface coordinate can then be made, based on both sets of data. The obscuring of surface features by specular reflection can thus be effectively eliminated.

Ink jet printing system and ink jet printing method

An image data signal value conversion is performed such that the volume of ink applied to image areas on a print medium to be printed by the overlapping portions of the printing element substrates is smaller than that applied to image areas on the print medium to be printed by other than the overlapping portions. Alternatively, the image data signal value conversion is performed such that the volume of ink applied to overlapping areas on the print medium to be printed by two consecutive printing main scans is smaller than that applied to other than the overlapping areas. For this reason, even when forming photographic images by using an elongate “joining head”, high-quality images with no density unevenness between overlapping areas and other areas on a print medium can be produced. Also in a serial type printing apparatus, uniform images with no seam stripes can be produced.
