However, according to the conventional color adjustment or screen color adjustment method of the conventional screen, it is inconvenient to arbitrarily adjust the desired state whenever necessary, and of course, the color or color stored in the memory of the microprocessor. If you select the mode according to the degree and adjust it to your preference or environment, the movie scene on the screen is the theme of cool summer sea.If the color composition of the screen is the warmth of winter, In this case, the selected mode does not match the current picture situation or the surrounding conditions.

Accordingly, an object of the present invention is to provide a method and apparatus for adjusting the four seasons color of a screen in which the mode is changed so that the mode is changed by automatic or user selection according to the change of season by setting the four seasons mode.

To this end, the present invention is a user's automatic or manual on the TV having the color and color control function of the screen set the four seasons mode to show the bright colors in spring, cool colors in summer, clear colors in autumn, warm colors in winter Selecting color adjustment, determining the season of the current date in case of automatic color adjustment, and automatically switching colors of spring, summer, autumn, and winter in order, and one season of four seasons if manual color adjustment. By adjusting the color by the step of selecting, and the step of switching to the color of the selected season to configure the screen with a sense of reality and lively.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration of a color TV having a function of manually or automatically converting color images in accordance with the present invention, wherein a remote controller signal input from the remote controller 1 is received by the remote controller module 2 and then a microprocessor ( 3) is entered. At this time, the microprocessor 3 receives the key signal by the remote control module 2 or the key matrix 4 to perform various functions of the television.

If the channel tuning key is pressed on the remote controller 1 or the key matrix 4, the microprocessor 3 generates a phase lock loop signal PLL for controlling the tuner 5 so that the tuner TUNER ( 5) allow the television broadcast signal received via the antenna 6 to be tuned.

The signal tuned by the tuner 5 is applied to the voice processing IC 8 and the chroma IC 9 via an intermediate frequency amplifier (IF) 7 from the microprocessor 3. The voice signal via the voice processing IC 8 receiving the signal is amplified by the voice amplifier 10 and then output to the outside through the speaker 11, and the color signals R, G, and B are the microprocessor. The video control signal from (3) is output from the chroma IC 9 which is input, and applied to the video processing IC 12.

At this time, the video processing IC 12 receives the data signal DATA, the clock CLK, and the strobe signal STROBE from the microprocessor 3 as well as the color signal for television broadcasting, which is output from the screen display IC 13. By processing color signals for on-screen display and providing them to the driver 14, the mode control logic is input through the two output ports P1 and P2 to adjust the internal brightness control unit or to adjust the size of the hole of the shadow mask. While adjusting, the monitor 15 displays the television broadcast and / or the on-screen display character whose color and color are adjusted.

2 shows the types of keys on the key matrix and the remote controller. The power key (POWER), channel up key (CH- ↑), channel down key (CH- ↓), volume up key (VOL- ↑), volume down Common keys such as the key (VOL- ↓), TV / Video Switch, TV / Video, etc., as well as the four season keys for switching to adjust the color manually, the TIMESET, the screen PICTVRE, SOUND, FUNCTION, and FOUR SEASON can be displayed on the monitor 15 through the screen display IC 12. ENTER key to select or execute the next routine, MODE UP key (MODE ↑), MODE DOWN key (MODE ↓) to select the desired program while moving sequentially while the program is displayed up and down or left and right. , Mode Left Move Key (Mode ←) Ui-dong mode is provided with the key (mode →).

The four-season color adjustment method of the screen of the present invention configured as described above is a color signal (R,) from the video processing IC 13 so that each can feel bright colors in spring, cool colors in summer, clear colors in autumn, and warm colors in winter. Port 1 (P1) and port 1 control signals to the driver 14 for controlling the operation of the monitor 15 by receiving the inputs G and B and signals for the hole size adjusting means of the shadow mask of the monitor 15. In a TV to be output through 2 (P2), when the user turns on the power key (step 20), the microprocessor 3 that recognizes the power supply supplies the necessary power to each of the internal parts, and the user selects a different menu. While controlling the key to perform the desired operation (step 21), while determining whether the user wanted to manually adjust the color by turning on the key four seasons (step 22), if not used Is the state that wants automatic color control, the microprocessor (3) receives the time information from the timer not shown in the drawing, and how many days are now through the register which stores the current time as well as the year, month and day. Receive the date information for (step 23).

The microprocessor (3) judges the input date as spring in March-May, summer in June-August, autumn in September-November, and winter in December-February (step 24). Through the two ports P1 and P2, the signal level as shown in Fig. 2A is outputted to the driver 14 (step 25). While continuously checking (step 26), the corresponding mode selection signal is output through the ports P1 and P2 (step 27).

On the other hand, if the key is turned on in step 22, it is the case that the user wants to select the color manually. Therefore, the microprocessor 3 checks whether the table of contents key (MENU) is turned on to select the color control mode among the program types. (Step 28), if it is on, a menu as shown in (b) of FIG. 3 is displayed on the part of the screen of the monitor 15 via the screen display IC 12 (step 29), and the user moves up or down the mode. After selecting the four seasons program using the left, right, and right movement keys (step 30), it is checked whether the movement key is turned on (step 31).
