Methods and systems for detecting and correcting chromatic aberration and purple fringing are disclosed. Chromatic aberration can be addressed by separating an image into color planes and then adjusting these to reduce chromatic aberration by using a specific calibration image (calibration chart) as an empirical method to calibrate the image acquisition device. Purple fringing can be corrected by initially addressing color aberration resulting from the lateral chromatic aberration (LCA). The LCA is first removed and then the correction is extended to purple fringing. A discovery is relied upon that the purple fringing is created in the direction of the chromatic aberration and is more pronounced in the direction of the chromatic aberration.

An image inspection device to automate and simplify inspection of an output image. A paper discharge tray of a printer is a different color from paper. A CCD camera is disposed above a paper discharge portion of the printer, at which paper is discharged, and can capture the whole upper face of the paper discharge tray. When, directly after a state in which there is no paper on the paper discharge tray, a print job is received and a first print-processed sheet is outputted to the paper discharge tray, a CPU controls the CCD camera to capture the paper discharge tray in this state. Captured image data including the paper is acquired, corrections are applied to the captured image data and to original image data by image processing, and image characteristics thereof are made substantially the same. Thereafter, the outputted image is inspected by comparison of the two data sets.

In a wavelet transform section, wavelet-transform coefficient signals are obtained by two-dimensional wavelet transformation, employing a low-pass filter which has a characteristic that its response at a frequency greater than a spatial frequency corresponding to grid pitch is approximately zero. Based on the direction of the grid judged by a direction judging section, a suppressing section applies one-dimensional wavelet transformation to a signal containing a grid component (when a vertical grid is used, signal HL1), in the grid direction. Then, a low frequency transform coefficient signal of the transform coefficient signals is made zero. The signal, made zero, and the remaining signals, are subjected to inverse one-dimensional wavelet transformation. In an inverse wavelet transform section, the original image is restored with a signal having a suppressed grid component.

Unique transparent polypropylene articles that can be tailored to become opaque when exposed to a sufficiently high temperature and which returns to substantially the same transparency level upon cooling. Such formulations include non-polypropylene polymeric constituents that exhibit refractive index measurements similar to the base clarified polypropylene at lower temperatures, as well as melting temperatures well below that for the base clarified polypropylene. Upon exposure to temperatures in close proximity to the melting temperature of the non-polypropylene polymeric constituents, the refractive index for such constituents will then become modified to the extent that the overall article appears at least partially opaque. In particular, the non-polypropylene polymeric constituents should exhibit melting temperatures well below that for the base clarified polypropylene, from about 60 to about 100° C. (well below the typical polypropylene melting temperatures of roughly about 160-190° C. for homopolymer and about 140-170° C. for typical random copolymer, both nucleated or non-nucleated). In this manner, a temperature sensitivity measuring thermoplastic article may be provided, and may be tailored to specific temperature ranges dependent on the melting temperatures exhibited by the non-polypropylene polymeric constituents. Methods of measuring temperature levels via the transformation of transparent polypropylene formulations to at least partially opaque versions thereof are also encompassed within this invention.
