Filed: 2000-12-27
Abstract: PURPOSE: An image processing method and an image processor are provided to change the color and the gradation of, for example, a face image of a person included in an image so that it may have desired color and gradation. CONSTITUTION: Object image data representing object images having plural color gradation is stored in a storage means(5), and a user selects a target image having a desired color gradation from object image displayed on a monitor(3). Picture data which is inputted to an image processing means(2) and includes the face image of a person is displayed on the monitor(3). The user observes the image displayed on the monitor(3) to select an area including the face image which should be changed to the same color gradation as the target image. The image processing means(2) extracts a flesh color area from the designated area and extracts cumulative histograms of the target image and the flesh color area as feature quantities indicating the color gradations. The color gradation of the designated area is changed to that of the target image, on the basis of these cumulative histograms to obtain processed image data(S1) which has had the color gradation changed.

Title: Congestion Control Method in Message Transfer System
Inventor: HWANG CHAN SIK
IPC: G06F13/362
Filed: 2000-12-29
Abstract: PURPOSE: A method for controlling congestion in a message transmission system is provided to prevent a message congestion state in a common bus by making each slave module generate a bus usage request if a required time should pass. CONSTITUTION: A user sets a prescaler value and an interval value and stores them in an interval value storage part(S61). A usage grant determination part reads the prescaler value and the interval value from the interval value storage part and stores them in its internal memory element. Then the usage grant determination part downcounts the stored prescaler value at regular intervals and updates the downcounted value into the present prescaler value(S62). The usage grant determination part judges whether the prescaler value is 0(S63). In case that the prescaler value is 0, the usage grant determination part decreases the interval value(S64) and judges whether the interval value is 0(S65). In case than the interval value is 0, the usage grant determination part concedes that a relevant slave module's bus usage request is valid, and executes bus usage arbitration(S66). In case that bus usage permission for the slave module is determined according the usage grant determination part's determination(S67), the slave module transmits messages through the bus(S68).

Title: Method and apparatus for fail-safe resynchronization with minimum latency
IPC: H04L7/02
Filed: 1998-10-09
Abstract: A method and circuit for achieving minimum latency data transfer between two mesochronous (same frequency, different phase) clock domains is disclosed. This circuit supports arbitrary phase relationships between two clock domains and is tolerant of temperature and voltage shifts after initialization while maintaining the same output data latency. In one embodiment, this circuit is used on a bus-system to re-time data from receive-domain, clocks to transmit-domain clocks. In such a system the phase relationships between these two clocks is set by the device bus location and thus is not precisely known. By supporting arbitrary phase resynchronization, this disclosure allows for theoretically infinite bus-length and thus no limitation on device count, as well as arbitrary placement of devices along the bus. This ultimately allows support of multiple latency-domains for very long buses.
