US Patent:

8628015, Jan 14, 2014
Filed:

Oct 31, 2008
Appl. No.:

12/263243
Inventors:

Ynjiun P. Wang - Cupertino CA, US
Shulan Deng - San Jose CA, US
Assignee:

Hand Held Products, Inc. - Fort Mill SC
International Classification:

G06K 7/10
US Classification:

23547201, 23546225, 23546245
Abstract:

There is described an indicia reading terminal that can be operative to capture a succession of frames of image data and that can be operative so that a certain frame of the succession of frames is subject to quality evaluation processing where a result of the quality evaluation processing is responsive to one or more of an incidence and sharpness of edge representations of the frame of image data.

Filed:

Sep 30, 2008
Appl. No.:

12/242244
Inventors:

Ynjiun P. Wang - Cupertino CA, US
Shulan Deng - San Jose CA, US
Assignee:

Hand Held Products, Inc. - Skaneateles Falls NY
International Classification:

G06K 7/10
US Classification:

235454, 23547201
Abstract:

A method for operating an indicia reading terminal is provided wherein image information can be processed for determining a location of a decodable indicia representation for a certain frame of image data, the result of the processing can be utilized for determination of an imaging parameter, the imaging parameter can be utilized for capture of a subsequent frame and the subsequent frame can be subject to image processing.

20100316291, Dec 16, 2010
Filed:

Jun 11, 2009
Appl. No.:

12/482979
Inventors:

Shulan Deng - San Jose CA, US
Ynjiun P. Wang - Cupertino CA, US
International Classification:

G06K 9/22
US Classification:

382166, 382313, 382244
Abstract:

There is described in one embodiment an indicia reading terminal having an image sensor pixel array incorporated therein, wherein the terminal is operative for decoding of decodable indicia and for providing color frames of image data for storage or transmission. An imaging terminal in one embodiment can include an image sensor having a hybrid monochrome and color image sensor pixel array including a first subset of monochrome pixels and a second subset of color pixels. Embodiments of data compression circuits and/or methods for processing image data from the hybrid image sensor pixel array are provided.

Filed:

Jul 22, 2011
Appl. No.:

13/188696
Inventors:

Ynjiun Paul Wang - Cupertino CA, US
Shulan Deng - San Jose CA, US
Assignee:

HAND HELD PRODUCTS, INC. - Skaneateles Falls NY
International Classification:

H04N 9/04
US Classification:

348273, 348272, 348E09002
Abstract:

Image processors and methods of processing image data from monochrome and color sensors, for example, pixels, are provided. The exposure time of the monochrome pixels is limited and the exposure time of the color pixels is extended to enhance image quality while limiting the “cross talk” that can interfere with prior art methods and devices. The monochrome and color sensors may be provided in two-dimensional image sensor arrays which can be provided in optical readers, for example, portable hand-held optical readers. Aspects of the invention can be applied to visual imaging, for example, in bar code or image handling applications, and to the detection and processing of any form of electromagnetic radiation.
