US Classification:

358 303, 358523, 382252

Abstract:

Error diffusion is performed upon input image data. In one aspect, multiple error diffusion processing elements perform error diffusion on a selected pixel in parallel. In another aspect, the error diffusion logic is integrally formed with a fast local memory in the same electronic device, such as an ASIC. The error data produced by the error diffusion logic for a pixel is buffered in the fast local memory until it is to be used by the error diffusion logic on other pixels. In still another aspect, a first-in-first-out (FIFO) buffer regulates or buffers the color image data between the output of a color conversion system, such as a colorant lookup table, and the input an error diffusion processing element. In yet another aspect, the error diffusion logic has tagging logic that produces and stores an indicator, either in the output data stream itself or in a separate area, to indicate whether a raster contains printable data.

International Classification:

G06K 9/00
G06K 9/36

US Classification:

382166, 382251

Abstract:

A method of transforming a n-bit data packet to a m-bit data packet with a lookup table. The lookup table includes at least one entry data packet and at least one respective delta value associated with each entry data packet. The method includes the acts of receiving an input data packet having n-bits, indexing the lookup table with at least a portion of the input data packet to obtain one of the at least one entry data packet, and decompressing the obtained entry data packet with the at least one respective delta value associated with the obtained entry data packet, thereby resulting in an output data packet having m-bits. The decompressing act includes using a portion of the input data packet to determine the number of delta values called for decompressing the obtained entry data packet. The method can be used in, for example, an image processor.

Appl. No.:

10/414664

Inventors:

Curt Breswick - Georgetown KY, US
Joseph Yackzan - Lexington KY, US

International Classification:

H04N001/04
H04N001/46

US Classification:

358/514000, 358/483000

Abstract:

Shifting of data out of at least one image sensor is controlled by a programmable sequencer table. Sampling of the shifted data is also controlled by the sequencer table. The sequencer table is programmed with at least one pattern for controlling shifting of data out of the image sensor and sampling of the shifted data. The pattern programmed into the sequencer table depends upon the image sensor. Output of the pattern from the sequencer table is controlled by a sequencer control block. The sequencer table and the sequencer control block may be included in a single application specific integrated circuit which may be implemented in, e.g., a scanner. This provides flexibility in the selection of image sensors, without requiring different circuits for controlling shifting of data out of the image sensors.

Inventors:

Stephen Cunnagin - Lexington KY, US

Ronald Garnett - Lexington KY, US
David Murray - Lexington KY, US

International Classification:

G06K009/00

US Classification:

358474000, 382318000

Abstract:

A scanner includes a scan bar, a first scan-bar homing reference, a second scan-bar homing reference and an image placement area. The scan bar is movable along a subscan axis. The second scan-bar homing reference is spaced apart along the subscan axis from the first scan-bar homing reference. The image placement area is located between the first and second scan-bar homing references. A broad method uses the scanner. One step includes performing a prescan or an image scan of an image by moving the scan bar along the subscan axis from the first scan-bar homing reference in relation to the image. Another step includes performing a prescan or an image scan of the image or of an additional image by moving the scan bar along the subscan axis from the second scan-bar homing reference in relation to the image or the additional image.

International Classification:

H04N 1/46

US Classification:

358504000

Abstract:

The present invention is directed to a system and method for reducing the memory requirement for offset and gain calibration to relieve the size/performance bottleneck in scanner systems. The resulting methodology produces visually equivalent scanned results with a substantial increase in performance, which results in a shorter amount of time required to output a first copy in, for example, an all-in-one device. Since the calibration step is often the bottleneck in scanner performance, this method noticeably speeds up scan and copy time. Implementing the decompression in hardware requires a minimal amount of hardware overhead and complexity. Thus, this method has a minimal impact on the size and cost of the scanner controller (e.g., an ASIC—application specific integrated circuit). Since compression only takes place at most once per scan, this added step has no significant impact on the overall scan time. By allowing dynamic grouping of pixels using a single calibration packet, the quality of the compensation can be optimized with the size of the compensation data being minimized. Adding the ability to shift the compressed deviation stored in the calibration packet, the range of the pixel-to-pixel deviation can be increased without impacting the size of the calibration data. This flexibility makes this invention applicable to future image sensors that may have widely varying deviations in pixel-to-pixel offset and gain values.

International Classification:

G06K 9/36

US Classification:

382244

Abstract:

A method for dynamically compressing image data to fit within a predefined memory capacity of a memory buffer includes dividing the image data into a plurality of data bands; determining an average band memory size in the memory buffer for each data band of the plurality of data bands; compressing a current data band at a compression quality level; and adjusting the compression quality level for a next data band of the plurality of bans to be compressed based on the average band memory size and a compressed memory size of the current data band.
