US Patent:

6707937, Mar 16, 2004

Filed:

Jul 14, 2000

Appl. No.:

09/615963

Inventors:

Arthur Sobel - Los Altos Hills CA
Todd S. Sachs - Menlo Park CA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G06K 900

US Classification:

382162, 345589

Abstract:

A method and apparatus for interpolating color image information are provided. One or more image data values for a portion of a digital image in a vicinity of a target pixel are received and stored in a local array. A processor determines whether there is an edge in the vicinity of the target pixel based on the data values in the local array. If there is not an edge in the vicinity of the target pixel, then long scale interpolation is performed on the image data values in the local array, in order to result in interpolating color information that is missing from the image. If there is an edge in the vicinity of the target pixel, then short scale interpolation is performed using image data values in a subset of the local array in a closer vicinity of the target pixel. As a result, accurate color rendering of a digital image is achieved, even in the presence of an edge portion that exhibits great contrast between regions of the image.

Filed:

Jul 19, 2002

Appl. No.:

10/199376

Inventors:

John S. Wenstrand - Menlo Park CA, US
Todd S. Sachs - Palo Alto CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G06K 9/36

US Classification:

382284, 382299

Abstract:

An image having higher resolution and/or better color is generated from multiple images of a subject taken by a handheld imaging device. The motion of the device, even when a user holds the device steady, gives the images perspectives that differ by an amount ranging from a fraction of a pixel to a few pixels. The differences in perspective provide different information about the subject that can be combined to create a better image. In particular, an image shifted by a non-integer number of pixels relative to another image provides information about portions of the subject that are between the pixels of the other image and usable for increasing resolution. Images shifted relative to each other by an integer number of pixels have aligned pixels that may provide different color information for the same portion of the subject when the aligned pixels correspond sensor elements having different color filters.

Filed:

Appl. No.:

10/284696

Inventors:

Xuemei Zhang - Mountain View CA, US
Ramakrishna Kakarala - Sunnyvale CA, US
Todd S. Sachs - Palo Alto CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G06K 9/00
G06K 9/32
G06K 9/36
H04N 1/46

US Classification:

382280, 382162, 382300, 358525

Abstract:

An image processing system and demosaicing method are provided to calculate estimated missing color sensor values in an image using a linear prediction from the raw color sensor value at the current pixel location. The raw image is divided into regions of sensor values, and the linear relations between color planes for each region are determined by a regression method that calculates the degree to which different color planes co-vary within each region The missing color sensor values per region are calculated as a scaled and shifted version of the raw color sensor values using linear regression coefficients determined from the local linear regression process.

Appl. No.:

10/801014

Inventors:

John Stewart Wenstrand - Menlo Park CA, US
Todd Stephen Sachs - Palo Alto CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

H01J 40/14
G09G 5/00

US Classification:

250221, 345211, 396 51

Abstract:

Eye detection is used as the basis for providing power management or other variations of operational parameters of a controlled device. The system includes an imager and eye detection processing which cooperate to detect light received from a person's eye. The eye detection processing generates an output that can be used for determinations regarding presence of one or more persons or presence of a specific person. This output is used as the basis for switching the controlled device between at least two power consumption states. Eye detection may also be used to allow a person to actively adjust operational conditions of the controlled device, since unnatural eye blinking patterns may be associated with particular commands.

International Classification:

H04N 9/73

US Classification:

3482261, 3482271

Abstract:

An image device, such as a digital camera, detects specific repeating patterns of signal variations by processing columnar information from the device's two-dimensional sensor array used to generate images. In one embodiment, the columnar information is derived from calculating row averages for two image frames, with each row average being a computed average of the multiple signal intensities generated from some or all of the sensors within a particular row. After the columnar information is determined for each of the two frames, a difference signal is generated as a sequence of the differences between the row averages for the first frame and the row averages for the second frame. This row averaging and frame differencing removes a large percentage of the signal energy that is not a result of the artifact of interest, such as the flicker generated by illumination having intensity fluctuations at 100 Hz or at 120 Hz. In some embodiments of the invention, the row averaging and/or the frame-to-frame comparison are deleted.

Abstract:

A device such as an optical mouse includes a light source for illuminating an imaging surface, thereby generating reflected images.
