DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full-color display device (8-bit 3-bit display for displaying image data).
Planes (planes for R (Red), G (Green) and B (Blue)), and R, G and B
In particular, the present invention relates to a menu display method in a full-color display device for displaying a menu in a full-color display device without a mask plane for menu display.

2. Description of the Related Art Conventionally, in a full-color display device without a mask plane for menu display, a menu is not displayed when an image is displayed (image display and menu display). Display cannot be performed simultaneously on one full-color display device). In order to simultaneously display an image and a menu, the menu is displayed on a dedicated display device for the menu. In other words, in the conventional menu display method in a full-color display device (the menu display method in a full-color display device not provided with a mask plane for menu display), one full-color display device displays an image and a menu at another time. Has been performed, or the display of the menu has been performed using a display device (dedicated display device for menu) different from the full-color display device for displaying an image.

In a menu display method in a full-color display device having a mask plane for menu display, the image display and the menu display are simultaneously performed on the full-color display device by using the mask plane. .

[0004]

In the above-described conventional menu display method in a full-color display device (a menu display method in a full-color display device without a mask plane for menu display), image display and menu display are performed. Since simultaneous operations cannot be performed in a full-color display device, there are the following disadvantages.

In order to display an image and a menu at the same time, a mask plane for displaying a menu must be added or a dedicated display device for the menu must be prepared. The cost of doing so increases.

[0006] Since the image and the menu are displayed at different times or the image and the menu are displayed on different display devices, the processing of the image data performed based on such display reference becomes complicated. Become.

FIG. 2 is a flowchart showing the processing of the menu display method in the full-color display device of this embodiment. This processing includes an image data input step 21, an output image data creation step 22, a menu data creation step 23, an LUT information creation step 24, and a data display step 25.

Next, the operation of the menu display system in the full-color display device according to the present embodiment thus configured will be described.

The processing information input unit 11 in the image data input means 1 stores a file name of an image data file in which image data to be processed (displayed) is stored and a processing range (a range of image data in the image data file). Is input, and the processing information is transmitted to the image data input unit 12.

The image data input unit 12 in the image data input unit 1 receives the image data to be processed stored on an auxiliary storage device such as a hard disk based on the processing information input by the processing information input unit 11. Image data specified by the processing information, which is composed of data of each band of R, G and B), is input to the memory (step 21).

The tone conversion table creating section 13 in the output value calculating means 2 converts the image data (image data having 256 tones for each of R, G and B bands) inputted by the image data input section 12 into R. , G and B, a table (gradation conversion table) for converting into image data (image data for output) having 240 gradations is generated, and the output value calculation unit 14 is activated. It should be noted that such a gradation conversion table is used and “256 gradations to 24
The “conversion to 0 gradation” is performed because the R,
This is for realizing coexistence of image data and menu data described later in each of the G and B planes.

Output value calculator 14 in output value calculator 2
Is a pixel value (a value indicating the tone at each pixel) in the image data having 256 tones for each of the R, G, and B bands, using the tone conversion table created by the tone conversion table creating unit 13. ), The pixel value (pixel value for display) in the output image data (image data having 240 tones for each band of R, G and B) is calculated, and the output pixel value having such a display pixel value is calculated. Create image data. That is, output image data corresponding to the image data input by the image data input unit 12 is created using the gradation conversion table (step 2).
2).

Menu creation section 1 in menu creation means 3
Reference numeral 5 denotes 16 tones out of 256 tones for each of R, G, and B planes in the display unit 19 (remains unused without being used in the output image data created by the output value calculation unit 14). Menu data (data indicating a menu for operating output image data)
Is created (step 23), and the menu data is transmitted to the data transfer unit 18. In this menu data, 1 is left without being used for output image data.
By using six gradations, a maximum of 4096 (= 1)
6 × 16 × 16) types of color expressions are possible (however,
Since the color representation of the menu becomes possible with about 16 colors, it is also possible to register the same value for each plane for R, G and B).

LUT information creation unit 1 in LUT creation means 4
Reference numeral 6 is used when displaying output image data (output image data created by the output value calculation unit 14) and menu data (menu data created by the menu creation unit 15) as an image and a menu, respectively. For this purpose, LUT information (LUT information for R, G, and B) indicating a luminance value (shade value) of 240 gradations for an image and a luminance value of 16 gradations for a menu is created (step 24). ), And transmits the created LUT information to the LUT setting unit 17.

The LUT setting section 17 in the LUT creating means 4
Is the LUT information created in step 24 (each L, G, and B LUT created by the LUT information creating unit 16).
UT information) to each of the L, G, and B L
Set to UT.

Data transfer unit 18 in data display means 5
Are output image data transmitted from the output value calculation unit 14 (output image data composed of data of each band of R, G and B created by the output value calculation unit 14) and from the menu creation unit 15. The transmitted menu data (menu data constituted by the data of each band of R, G and B created by the menu creating unit 15) and the planes for R, G and B in the display unit 19 Transfer to

The display unit 19 in the data display unit 5 displays the data relating to each of the R, G and B bands in the output image data transferred from the data transfer unit 18 into the RUT set by the LUT setting unit 17. , G and B are passed through each LUT to display an image having 240 gradations for R, G and B on the display. Further, by passing the data relating to each band of R, G and B in the menu data transferred from the data transfer unit 18 through each of the R, G and B LUTs set by the LUT setting unit 17, A menu having 16 gradations for each of R, G and B is displayed on the display (step 2).
5).

In the menu display system in the full-color display device of this embodiment, image data having 256 tones for each of the R, G and B bands is converted to an output image having 240 tones for each of the R, G and B bands. The case where the data is converted into data and 16 gradations of R, G and B are used for displaying a menu has been described. Here, the numerical values such as “240 gradations” and “16 gradations” are set so as to satisfy the condition that the image and the menu can be displayed simultaneously without essentially changing the image data. Value. Therefore, if such setting conditions are satisfied, “256 gradations” are changed to “24 gradations”.
It is also possible to realize a menu display method in the full-color display device of the present invention by converting into a gradation of a numerical value other than “0 gradation”.

[0029]

As described above, the present invention makes it possible to display a menu using a plane for displaying image data, thereby enabling a menu display in a full-color display device without a mask plane for displaying a menu. Images and menus in one full-color display without the need for a dedicated mask plane or dedicated display for displaying menus (without the expense of performing such installations) There is an effect that they can be displayed at the same time (the processing of image data performed based on such display reference can be simplified).
