Appl. No.:

09/399933

Inventors:

Shang-Hung Lin - San Jose CA

Assignee:

Seiko Epson Corporation - Tokyo

International Classification:

G09G 508

US Classification:

345157, 345158, 353 42, 353121, 348744

Abstract:

An interactive presentation control system, used with a display computer, a computer-controlled image projector, a laser pointer, and a projection screen, comprises a digital camera and a control module. The display computer generates electronic images which are projected onto the projection screen as presentation images. During operation, a presenter uses the laser pointer to trace out a pre-established gesture spatial pattern onto the presentation image. The digital camera acquires these presentation images from which images a processing section in the control module analyzes and identifies the gesture spatial pattern. The identified gesture spatial pattern is compared to a set of pre-established patterns to find a match and to subsequently select a correlated display command. The display command, which can be executed within the control module or transmitted to the display computer, changes the presentation image by an action such as: advancing to the next image, highlighting a text segment, or zooming in on the image.

Abstract:

An automatic white balancing method and system. A modification of “color in perspective” white balancing technique is implemented. Rather than a default projection plane used by the typical white balancing technique, the projection plane for a RGB space is automatically selected to allows the projected reference gamuts in the projection plane to be as disjoined as possible, thereby making them as uncorrelated as possible. In turn, automatic white balancing is performed using the color temperature associated with the projected reference gamut most correlated with the projected gamut of an image sensor.

International Classification:

H04N 5/225
H04N 17/02

US Classification:

34820799, 3482221, 348180

Abstract:

Method and system for a single-chip camera where an image sensor is a single-chip digital color imaging device that incorporates a sensor array that captures still or full-motion video and converts the images to digital data. Moreover, the image sensor employs a built-in correlated double sampler, an internal analog-to-digital converter, and a timing circuitry. Output from the sensor is an 8-bit or more raw data, horizontal sync signals, and vertical sync signals. The output raw data may then be fed into a compression circuit that generates packets of compressed output data. The compressed data is transmitted with a USB transceiver using isochronous packets. The packets are then received, decompressed, and color processed by a host PC.

Abstract:

A method and system for image chroma suppression of an image sensor system. Chroma suppression is performed to reduce the false color phenomena. The amount of chroma suppression is performed based on the strength of spatial frequency for a current processing pixel measured during edge detection. In determining the strength of spatial frequency of the current processing pixel, only a small number of green pixel values are needed, regardless of whether or not the current processing pixel is a green pixel within the Bayer pattern. As such, line buffers from the color interpolation module of an image sensor system can also be used for the purpose of chroma suppression.

US Classification:

382312, 382307

Abstract:

A device driver for an image capturing device. The device driver detects and monitors characteristics of the image capturing device as well as that of a host machine processing image data coming from the device. Based on the detected and monitored characteristics, the device driver coordinates image processing on the host machine by configuring on-the-fly a plurality of functional modules supported by the host machine for performing various image processing tasks. When monitored characteristics warrants a different configuration of functional modules, the device driver on-the-fly reconfigures the functional modules.

International Classification:

G06K 9/40

US Classification:

382167, 382162, 382274

Abstract:

Methods and systems for processing image data are described. A scene classifier determines the probabilities that various scene classes are associated with the image data. A gamut mapper determines the probabilities that various combinations of illuminant color and scene class are associated with the image data. The probabilities from the scene classifier are used to weight the probabilities from the gamut mapper. The weighted results can be used to select an illuminant color. The image data can be adjusted to compensate for the selected illuminant color.

Abstract:

An optical image stabilization system for a camera module is disclosed. The stabilization system comprises a voice coil motor (VCM), at least one digital gyroscope for receiving signals from the VCM, and an angular velocity sensor for receiving signals from the digital gyroscope and outputting an angular position error signal. The stabilization system further comprises signal processing logic for receiving the error signal, and comparing the error signal to a reference signal and providing a stabilized image based upon that comparison, wherein the hard-coded logic, digital gyroscope and rate and position sensor resides on the same chip.
