摘要:
An image capture and compositing apparatus for a photobooth (10) photographs a customer against a fixed color background (28), extracts the customer from that image and then inserts the extracted customer image into an arbitrary background image in such a manner that there are no noticeable artifacts between the inserted image and the background image and so that it appears that the subject was actually situated in the background scene when photographed. The imagery processing mechanism employed generates a pair of masks, one of which is associated with the foreground image and the other of which is associated with the background image. These masks are used to extract the subject (160) from an image of the subject against a reference color backdrop, to define what portion of the background image is to be blanked out and to controllably blend the border of the inserted subject image with the background image. The photobooth contains a customer lighting system (50,42) located above and behind the position where the customer is seated. A separate backdrop lighting system (32) is located behind the customer and illuminates a blue reference backdrop against which the customer is photographed and which is photographed per se to provide a reference for mask production.

A method for providing user interaction with a printed page (10) includes providing artwork (20) for a first page to be printed; providing a printing model to simulate a first printed page using the artwork; simulating the first page to be printed using the printing model; extracting a first set of features from the first simulated page (220); and embedding the first set of extracted features in a first URL (270). The invention includes printing the first page; capturing a digital image of the printed page (415) with a mobile device (400); extracting features (430) from the digital image; generating the URL associated with the digital image using the features extracted from the digital image; and navigating to the generated URL using a web browser (470).

A system of aligning a stamp to a stamp backing plate includes a fixture with a first alignment feature mount on a platen; a first stamp with a second alignment feature which matches the first alignment feature; aligning the first stamp to the fixture using the first and second alignment features; transferring the first stamp from the fixture to a first stamp backing plate maintaining registration; a second stamp with a third alignment feature which matches the first alignment feature; aligning the second stamp to the fixture using the first and third alignment features; and transferring the second stamp from the fixture to a second stamp backing plate while maintaining registration.

Embedding data in printed image features on a receiver printed with an offset printing process includes a first offset printing member (240) for forming an image (320) on the first offset printing member. A second offset printing member (260) is roughened in one region (280) of the second offset printing member within a boundary of an image feature on the first offset printing member to embed data (330). Ink is applied to the first offset printing member and transferred from the first offset printing member to the second offset printing member. The ink from the second offset printing member is applied to a receiver (305) and the embedded data is printed within the boundary of the at least one image feature transferred to the receiver.

A method of encoding data in printed halftone image features on a receiver includes providing a relief printing member; encoding first embedded data in the relief printing member by modifying surfaces of a first plurality of halftone dots; and printing the halftone image on the receiver.

A method for adjusting dot-gain for a halftone binary bitmap file comprises inputting a halftone binary bitmap file consisting of binary pixels (400) to an asymmetric digital filter (500). The binary pixels are filtered with the asymmetric digital filter and generates multi-level pixels (506). The multi-level pixel are compared to a preset level (408) and generates a binary pixel output (410). The binary pixel output is collected and forms an adjusted halftone binary bitmap file (270).

The present invention is a method of adjusting a color in a color proof (112) printed with primary colors cyan, magenta, yellow, and black. It is accomplished by: a) combining the cyan bitmap (2), magenta bitmap (4), yellow bitmap (6), and black bitmap (8) into one multi-bit image (202) and b) imaging each of the primary colorants with the multi-bit image (202).
摘要:
An apparatus and method for applying dot-gain (110) compensation to halftone bitmap files used in printing a digital halftone image. Dot-gain is added by thresholding (250) the output of a convolution of the original bitmap image with a spatial filter (200). Averaging (220) is performed to specify the level of the threshold to be applied. The level of dot-gain applied is a function of the threshold level.
摘要:
A method of tuning a printer by printing a pattern, which beats against a component within the printer includes designing a first pattern, which has a spatial frequency, which is different from a first component spatial frequency. A first pattern is printed and banding is measured. To minimize banding a characteristic of the first component is adjusted.

An image processing apparatus (10) for sheet thermal print media includes an imaging drum (300) for holding thermal print media (32) and donor material (36) in registration on the vacuum imaging drum. In order to decrease the incidence of visible defects in images produced by the apparatus, the imaging drum (300) has its axis in parallel with the feed direction of the media. A method for improving the quality of images produced by an image processing apparatus (10) having a horizontally disposed imaging drum (300), which includes loading pre-cut, thermal print media into the image processing apparatus in a direction which is parallel to the axis of the imaging drum is also included.
