Patent number: 7061541Abstract: An apparatus to compensate a color carrier in an image processing system to convert an input analog image signal into a digital image signal includes a detector, a phase-locked loop unit, a difference detector, and a color signal processor. The detector detects a frequency of the color carrier in a color signal of the digital image signal. The phase-locked loop unit generates a subcarrier frequency by performing a phase-locked loop operation on a system clock signal applied to the image processing system. The difference detector detects a difference between the frequency of the color carrier and the subcarrier frequency. The color signal processor compensates for a phase deviation of the color carrier of the color signal using the subcarrier frequency generated by the phase-locked loop unit.Type: GrantFiled: May 6, 2003Date of Patent: June 13, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Hak Jae Kim

Patent number: 7015973Abstract: A method and an apparatus for generating a coast signal for enabling or disabling a phase comparator in a phase-locked loop of image processing apparatus. The phase-locked loop generates a sampling clock signal, which is used to convert an analog image signal into a digital image signal in response to a composite sync signal including a vertical sync signal and a horizontal sync signal. An enabled coast signal is generated at period other than detected horizontal sync period to prevent the phase comparator from comparing the composite synce signal to a reference signal, and a disabled coast is generated at periods corresponding to the horizontal sync period to permit the phase comparator to compare the composite synce signal to the reference signal.Type: GrantFiled: September 25, 2002Date of Patent: March 21, 2006Assignee: Samsung Electronics Co., LTDInventor: Hak-Jae Kim

Patent number: 7009660Abstract: A device and a method for automatically discriminating formats of video signals input to a monitor and processing the respective signals in accordance with the identified formats are provided. The device automatically identifies whether signals input to the same input port are RGB type PC signals or YPbPr type HDTV signals and processes the signals in accordance with the identified formats. Therefore, users have only to install a single input port commonly used to receive PC signals and HDTV signals rather than installing separate input ports for separately receiving PC signals and HDTV signals.Type: GrantFiled: March 11, 2002Date of Patent: March 7, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Hak-jae Kim
