Description

TV Color Enhancement Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color enhancement processing apparatus for a television, and more particularly, to adjust a white balance of an entire screen for an image signal reproduced by a television to emphasize a specific color or to emphasize a color for a specific area of a screen A color emphasis processing apparatus for televisions for which processing is executed.

Current color televisions have pixels corresponding to the R / G / B color beams as the color beams emitted from the R / G / B electron guns in the CRT device collide with the R / G / B pixels formed on the fluorescent panel. The color of the dot is emitted to reproduce the color image. That is, in such a television, a color image approximating a natural color is realized by a combination of R / G / B color beams. A broadcast video signal transmitted from a broadcasting station or an image signal applied from a video tape recorder, for example, is R in the image processing system. When processed as a / G / B color signal and applied correspondingly to the R / G / B electron gun of the CRT device, the R / G / B color beam is emitted from the R / G / B electron gun to reach the fluorescent panel. The pixel point of the R / G / B color is emitted to reproduce a color image.

Typically, the R / G / B color beam emitted from the R / G / B electron gun is a three-element for depicting a color image, and when the R / G / B color beam is emitted at the same level, The R / G / B pixel points show the same amount of light emission, so that white color is drawn on the screen of the CRT apparatus. Therefore, the color beam of the CRT apparatus can be corrected based on the level of the white color by the harmony of the R / G / B colors.

In this case, for the CRT apparatus of the television, for example, a background screen of a specific color is generally applied to display the noise component so that the image noise component is not displayed on the screen during the period of no video signal. That is, the white balance by the R / G / B color is adjusted in a state where a specific color ratio is emphasized. As a specific color by adjusting the white balance, a blue system (eg, Korea) or a red system (eg, Europe) is used. Regional), green systems (eg Japan).

However, the color image drawn on the CRT device is largely dependent on the R / G / B color level included in the image signal at the time of imaging, so that the color image displayed on the screen of the CRT device is applied to the color image. It is customary to set regardless of the corresponding voice signal. Therefore, for example, when a description of a color image corresponding to an audio signal is provided, it can be foreseen to provide a color image with more realism. That is, when an audio signal, for example, 'sky is blue' is transmitted corresponding to the current video signal frame, the color of the 'sky' is usually reproduced only at the level of the image signal captured, but is depicted on a CRT apparatus, for example. When the color level of the color image is corresponding to the color of the audio signal (eg, 'sky'), for example, the blue level is emphasized, a more visual color image can be provided.

First, when the color emphasis processing mode is not specified by the remote controller 10, the controller 12 controls the normal image reproduction processing. When a specific channel is selected by the remote controller 10, the channel is selected. The video signal component applied to the channel is controlled by the video IF processor 14 by the predetermined video IF signal and applied to the video processor 16. Then, the image processing unit 16 reproduces the image IF signal as an R / G / B signal and applies it to the CRT device 18 so that a color image is reproduced on the CRT device 18.

In such a state, the control unit 12 waits for the setting of the color emphasis processing mode by the color emphasis mode button 10a of the remote controller 10, and the color emphasis mode button 10a by the color emphasis mode button 10a during the waiting. If the processing mode is specified, the color emphasis ID code detection result from the color emphasis ID code detection unit 20 is awaited in step 30 of FIG.

And a line memory 630 for recording / reading the color level of each provided horizontal line and providing the color emphasis processing unit 66 line by line.

Next, the operation of the color emphasis processing apparatus of the television according to the second embodiment of the present invention will be described in detail.

First, when the color emphasis processing mode is not specified by the remote controller 50, the controller 52 controls the normal video reproducing process and selects a channel when a specific channel is selected by the remote controller 10. Therefore, the video signal component of the tuned channel is IF converted by the video IF processor 54 based on a predetermined video IF signal and applied to the video processor 16. The image processing unit 16 reproduces the image IF signal as an R / G / B signal and applies it to the CRT device 18 so that a color image is reproduced on the CRT device 58.

In such a state, the controller 52 waits for the color emphasis ID code detection result from the color emphasis ID code detection unit 60 when the color emphasis processing mode by the color emphasis mode button 50a of the remote controller 50 is designated. When the color emphasis ID code detection unit 60 is notified of the detection of the color emphasis ID code including the first and second color emphasis codes during the waiting period, the control unit 52 determines the color emphasis area determination unit 62. In addition to providing a color enhancement processing enable control signal (EN) to the image processing unit 56, a mode control signal (M) is applied to the image processing unit 56, the color applied from the color emphasis processing unit 66 under the color emphasis processing mode Control to reproduce the highlighted video signal.

Accordingly, the color enhancement area determination control unit 624 of the color emphasis area determination unit 62 is activated, and an image signal Vin of one frame to be processed by the image processing unit 56 is generated by the data conversion unit 620. The digital synchronization signal detector 622 detects a horizontal synchronization signal from the image signal Vin and applies it to the color enhancement area determination controller 624. Then, the color emphasis area determining controller 624 generates a sampling clock signal SCLK based on the horizontal synchronization signal and applies the sampling clock signal SCLK to the horizontal line sampling unit 626. Accordingly, the horizontal line sampling unit 626 is applied. ) Samples the image data of one frame converted by the data converter 620 serially in units of horizontal lines, and applies the same to the color filter unit 628, and R forming the color filter unit 628. The / G / B color filter detects color components (R / G / B colors) in pixel units from the results of sampling in the horizontal line units.

Color filtering data for each pixel filtered by the color filter unit 628 is transferred to the line memory 630 by a memory write / read control signal R / W 'applied by the color emphasis area determination controller 624. It is recorded sequentially and then applied to the color emphasis processor 66.

In this state, the control unit 52 controls the color emphasis items (eg, 'sky', 'cloud', 'designated by the first and second color emphasis codes detected by the color emphasis ID code detection unit 60). Acid ', ---) and its accent color components (eg' blue ',' blue ', ---;' white ',' white ', ---;' blue ',' blue ' '---' is determined and the color emphasis control signal C is applied such that only a specific color level is increased based on the first and second color emphasis codes among the pixel color levels recorded in the color emphasis processing section 66. Accordingly, the color level of the pixel unit stored in the color emphasis processor 66 is applied to the image processor 56 in a state in which the color level of the pixel unit is emphasized compared to the original color level.

That is, for example, when the video signal of the type shown in FIG. 5 (b) is applied to the frame of the current processing target, a color emphasis ID code transmitted from a broadcasting station is included in the state in which the word 'green' is included in the audio signal. If the first color accent code indicates 'mountain' as the color highlight item and the second color accent code indicates 'blue' as the accent color component, the data conversion part 620 performs digital conversion on the horizontal line. In the sampling unit 626, the sampling is performed in units of horizontal lines, and the color filtered by the color filter unit 628 is such that the color component of the area 58a representing 'mountain' of FIG. 5 (b) is generally green (G). As detected, the control unit 52 applies the color emphasis control signal C to the color emphasis processing unit 66 to perform the green system emphasis processing by the second color emphasis code. Accordingly, an image signal in which the color of the area 58a of the 'mountain' shown in FIG. 5 (b) is green-reinforced and applied to the image processor 16, and the green color is reinforced by the image processor 16. Is applied to the CRT device 58 to be displayed. In this case, the green color component of the entire screen displayed on the CRT apparatus 58 can be processed to be emphasized, thereby improving the visibility as the specific color of the color image (green in the above example) is emphasized.

As described above, according to the color emphasis processing apparatus of a television according to the present invention, when a color emphasis item included in an audio signal and a color component of the color emphasis item are created and transmitted as a color emphasis ID code, Since the color component of the entire screen or the color component of a specific region is emphasized on the basis, the visual effect on the color image displayed on the CRT apparatus can be further improved.
