DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a white balance adjustment, a focus adjustment, a brightness adjustment, a contrast adjustment, a sharpness adjustment, and an amplitude adjustment in a TV (television receiver), a display monitor television set (hereinafter, a monitor TV set) and the like. This is related to the display of a pattern.

2. Description of the Related Art Conventionally, for a white balance adjustment, a focus adjustment, a brightness adjustment, a contrast adjustment, a sharpness adjustment, and an amplitude adjustment in a monitor TV set, a device having a signal generation function is separately prepared in advance.
Alternatively, a dedicated signal or character for performing various adjustments is output by using a signal generator incorporated in the monitor TV set, and the adjustment is performed.

FIG. 8 is a block diagram showing a case where white balance adjustment, focus adjustment, brightness adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment are performed in a conventional monitor TV set. The monitor TV set 21 is connected to the external signal source 22 or the monitor TV set 2
1 uses a character generator 23 that outputs a dedicated image for adjustment prepared exclusively for the inside, and sets the output image to an image type suitable for each adjustment. By inputting the signal output from the external signal source 22 or the character generator 23 to the monitor TV set 21 to be adjusted, the image of the monitor TV set 21 to be adjusted is switched from the normal image to the adjustment image. In this state, each adjustment is performed on the operation unit 24 of the monitor TV set 21, and the adjustment is repeatedly performed until a desired adjustment result is obtained.

[0004]

However, in the above-mentioned conventional configuration, in order to perform various adjustments, a signal generator capable of generating a signal of a type suitable for each adjustment is provided inside or outside the monitor TV set. When the above device is not prepared, various adjustments are very difficult to perform, and even when the above device is prepared, adjustment is performed to switch to an image dedicated to adjustment. However, there is a problem that a simple adjustment cannot be performed while continuously checking the images up to this point.

[0005] The present invention solves the conventional problems.
Especially for easy white balance adjustment, focus adjustment, brightness adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment without preparing a device having a dedicated signal generation function or preparing a dedicated character generator inside the monitor TV set. It is an object of the present invention to provide a screen display control device capable of simplifying the structure of a monitor TV set for displaying characters and performing various adjustments.

[0006]

In order to achieve this object, a screen display control device according to the present invention comprises a television receiving control device.
Machine and display monitor television set (hereinafter,
A monitor TV set), an on-screen character display device for displaying various information on a screen, a microcomputer for controlling the on-screen character display device, and character data to be output to the on-screen character display device. ROM

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A screen display control device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows white balance adjustment using on-screen character characters.
FIG. 2 is a block diagram illustrating a display of each adjustment pattern for focus adjustment, brightness adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment.

In FIG. 1, reference numeral 1 denotes a microcomputer, and 2 denotes an on-screen character display device for displaying various information on a screen. The on-screen character display device 2 is controlled by the microcomputer 1. Reference numeral 3 denotes a control panel such as a push switch or a remote controller for obtaining a request from the outside, which is an input device for requesting display of an adjustment character pattern. Reference numeral 4 denotes a ROM that stores on-screen character data to be output to the on-screen character display device 2.

Next, the operation of the above-mentioned constituent device will be described. In a normal use state, the microcomputer 1 operates in response to various external requests from the control panel 3, and the microcomputer 1
RO on the V-set screen according to the situation
A combination of characters and numbers to be read and displayed from M4 is calculated and transmitted to the on-screen character display device 2. The on-screen character display device 2 that has received the data from the microcomputer 1 adds the received data to the video signal in the form of a character signal and outputs the image as a monitor TV set image.

The microcomputer 1 receives from the control panel 3 instructions to perform white balance adjustment, focus adjustment, bright adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment, and further displays an adjustment image display from the control panel 3. Upon receiving the designation, the type of the designated adjustment is analyzed, the image of the output character required for performing the adjustment is calculated by calculation, and the type of the adjustment content is determined. Then, the microcomputer 1 determines the type of image that is optimal for each adjustment content, and stores the optimal character data for each adjustment in the ROM.
Take out from 4.

The microcomputer 1 which has taken out the character data from the ROM 4 designates the character data and the display position of this character on the on-screen character display device 2 in accordance with various adjustment contents. The on-screen character display device 2 receiving the data from the microcomputer 1 adds the received data to the video signal in the form of a character signal and outputs the image as a monitor TV set image.

According to the above-described processing, in the example of the screen display during the adjustment indicated by reference numeral 6 in FIG. 2, several to ten characters of white “□” are displayed near the center of the screen indicated by reference numeral 5 in FIG. By displaying one large frame by arranging several characters, it is possible to display a character pattern which is a window for white balance adjustment.

Reference numeral 7 in FIG. 3 shows a display example of an on-screen character for judging the focus at a plurality of positions during focus adjustment, and reference numeral 8 in FIG. Numeral 9 in FIG. 5 shows a display example of an on-screen character for determining shading at the time of contrast adjustment, and numeral 10 in FIG. 6 shows a display example of an on-screen character for determining fineness at the time of sharpness adjustment. Reference numeral 11 in FIG. 7 indicates a display example of an on-screen character for determining the size of the display screen at the time of amplitude adjustment.

According to the above-described embodiment, an on-screen character display device that originally displays on-screen character characters on a screen for the purpose of transmitting various states of a monitor TV set and various information displays to a user. By devising the control, it is possible to simply output an adjustment image required for various adjustments such as white balance adjustment, focus adjustment, bright adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment.

Further, since the adjustment image can be output without switching the displayed image to the adjustment image, the white balance adjustment, the focus adjustment, the brightness adjustment, the contrast adjustment, and the sharpness can be performed while continuously checking the image. Adjustment and amplitude adjustment can be performed.

[0017]

As described above, according to the present invention, the white balance adjustment, the focus adjustment, the brightness adjustment, the contrast adjustment, the sharpness adjustment, and the amplitude adjustment are not particularly required, and a special signal generator is not required. During balance adjustment, focus adjustment, brightness adjustment, contrast adjustment, sharpness adjustment, and amplitude adjustment, adjustments can be made without switching the video output to the screen, and white balance adjustment, focus adjustment, brightness adjustment, and contrast adjustment Even an operator who does not have expertise in sharpness adjustment and amplitude adjustment can easily make adjustments.
