Description

색위상보정장치Color Phase Correction Device

본 발명은 색위상보정장치에 관한 것으로, 특히 수신되는 방송신호의 각 채널마다 색위상을 보정하여 메모리에 저장하고, 채널선택시 자동으로 저장된 색위상보정데이타를 참고하여 색위상보정이 가능하도록 한 자동색위상보정장치에 관한 것이다.The present invention relates to a color phase correction apparatus, and in particular, to correct color phase for each channel of a received broadcast signal and store the result in a memory, and to perform color phase correction by referring to the color phase correction data automatically stored when selecting a channel. It relates to an automatic phase correction device.

일반적으로, NTSC방송의 경우 방송국별 송출 데이터의 색상(tint)이 각각 다르다. 그러므로, 사용자는 최적의 색상으로 시청하기 위해 수동으로 색상(tint)을 가변한다.In general, in the case of NTSC broadcasting, the tint of transmission data for each broadcasting station is different. Therefore, the user manually changes the tint to watch in the optimal color.

이러한 방법은 한 방송만을 시청할 경우에는 문제가 없으나, 다른 방송을 시청하기 위해 채널을 전환하면, 이전 채널에 맞게 색위상이 설정되어 있으므로, 현재 선택한 채널에 맞도록 다시 색위상조정을 해야 최적의 화질을 얻을 수 있었다. 이렇게 종래에는 채널변경시마다 색위상을 각각 수동으로 재조정해야하는 불편함이 따랐다.This method does not have a problem when watching only one broadcast, but if you switch channels to watch another broadcast, the color phase is set to match the previous channel, so you need to adjust the color phase again to fit the currently selected channel. Could get Thus, in the conventional art, the inconvenience of having to readjust the color phase manually at each channel change has been accompanied.

그러므로, 본 발명의 목적은 위와같은 불편함을 해소하기 위해 각 채널마다 색위상을 보정하여 색위상보정데이터를 채널별로 메모리에 저장하고, 이후 해당 채널을 선택했을 때 메모리에 저장된 색위상보정데이타를 참고로하여 색위상 보정이 자동으로 이루어지도록 한 자동색위상보정장치를 제공함에 있다.Therefore, an object of the present invention is to correct the color phase for each channel in order to solve the above inconvenience, and to store the color phase correction data in the memory for each channel, and then the color phase correction data stored in the memory when the corresponding channel is selected For reference, the present invention provides an automatic phase correction device that automatically performs color phase correction.

The color phase correction apparatus including a control unit for controlling to store in.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명하겠다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 색위상보정장치를 보여주는 도면이다. 본 발명의 장치는 방송신호를 수신하는 튜너부(11)와 튜너부(11)에서 수신된 신호를 복조하는 복조부(12)를 구비한다. 색위상보정부(13)는 복조부(12)에서 복조된 색신호의 위상 틀어짐을 보정하여 디스플레이부(14)로 출력하며, 이때의 색위상보정데이타는 메모리(17)에 저장된다. 그리고, 본 발명의 장치는 키입력부(15)와 각 부를 제어하는 제어부(16)를 구비한다.1 is a view showing a color phase correction apparatus of the present invention. The apparatus of the present invention includes a tuner section 11 for receiving broadcast signals and a demodulator section 12 for demodulating the signals received at the tuner section 11. The color phase compensator 13 corrects the phase shift of the color signal demodulated by the demodulator 12 and outputs it to the display unit 14, and the color phase correction data at this time is stored in the memory 17. In addition, the apparatus of the present invention includes a key input unit 15 and a control unit 16 for controlling each unit.

도 1에서, 튜너부(11)는 방송국으로부터 송출되는 방송신호를 수신하여 복조부(12)로 출력한다. 복조부(12)는 튜너부(11)에서 수신된 방송신호를 복조한다. 색위상보정부(13)는 복조된 색신호의 위상 틀어짐을 보정하여 디스플레이부(14)로 출력한다. 그리고, 색위상 보정데이타를 현재 설정된 채널데이타와 함께 메모리(17)에 저장한다. 다른 채널을 선택하는 타채널선국신호가 키입력부(15)를 통해 입력되면, 제어부(16)는 채널변환신호를 튜너부(11)로 출력한다. 튜너부(11)는 제어부(16)의 제어하에 선택된 채널에 해당하는 방송신호를 수신한다. 복조부(12)는 변환된 채널의 방송신호를 복조한다. 또한, 제어부(16)는 메모리(17)에 현재 수신된 방송신호의 채널에 해당하는 색위상보정데이타가 있는지 판단한다. 제어부(16)는 메모리(17)에 현재 선택된 채널에 해당하는 색위상보정데이타가 있으면, 색위상보정부(13)로 색위상보정데이타를 출력한다. 색위상보정부(13)는 메모리(17)로부터 인가되는 색위상보정데이타를 참고하여 복조된 방송신호의 색위상 틀어짐을 보정한다. 그러나, 메모리(17)에 현재 수신된 방송신호의 채널에 해당하는 색위상보정데이타가 없으면, 색위상보정부(13)는 복조된 신호의 색위상을 보정하여 디스플레이부(14)로 출력하고, 메모리(17)에 색위상 보정데이타를 현재 선택된 채널과 함께 저장한다.In Fig. 1, the tuner unit 11 receives a broadcast signal transmitted from a broadcasting station and outputs it to the demodulator 12. The demodulator 12 demodulates the broadcast signal received by the tuner 11. The color phase compensator 13 corrects the phase shift of the demodulated color signal and outputs it to the display unit 14. The color phase correction data is stored in the memory 17 together with the channel data currently set. When another channel selection signal for selecting another channel is input through the key input unit 15, the control unit 16 outputs the channel conversion signal to the tuner unit 11. The tuner 11 receives a broadcast signal corresponding to a selected channel under the control of the controller 16. The demodulator 12 demodulates the broadcast signal of the converted channel. In addition, the controller 16 determines whether there is color phase correction data corresponding to the channel of the broadcast signal currently received in the memory 17. The controller 16 outputs the color phase correction data to the color phase compensator 13 when the color phase correction data corresponding to the channel currently selected in the memory 17 is present. The color phase compensator 13 corrects the color phase shift of the demodulated broadcast signal with reference to the color phase correction data applied from the memory 17. However, if there is no color phase correction data corresponding to the channel of the broadcast signal currently received in the memory 17, the color phase compensator 13 corrects the color phase of the demodulated signal and outputs it to the display unit 14, The color phase correction data is stored in the memory 17 together with the currently selected channel.

상술한 바와같이, 본 발명은 수신되는 방송신호의 각 채널마다 색위상을 보정하여 그 색위상보정데이타를 메모리에 저장하고, 채널선택시 자동으로 저장된 색위상보정데이타를 참고하여 색위상보정이 가능하도록하여 어느 채널을 선택하더라도 사용자가 설정한 최적의 화질로 시청할 수 있는 효과가 있다.As described above, the present invention can correct the color phase for each channel of the received broadcast signal, store the color phase correction data in the memory, and perform color phase correction with reference to the automatically stored color phase correction data upon channel selection. By selecting any channel, the user can watch at the optimal quality set by the user.
