BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrolling screen transform apparatus, and more particularly to a scrolling screen transform apparatus for screen transformation by address shifting.

SUMMARY OF THE INVENTION An object of the present invention is to provide a scrolling screen deformation apparatus for screen deformation such as horizontal stretching or vertical stretching of a screen by applying address shifting.

Scrolling screen deformation apparatus for achieving the above object,

A horizontal address storage unit for storing M + b horizontal address values;

A vertical address storage unit for storing N + a vertical address values;

A horizontal address generator for generating a horizontal address stored in the horizontal address storage;

A vertical address generator for generating a vertical address stored in the vertical address storage unit;

A horizontal shift register for selecting M addresses among the M + b horizontal addresses generated by the horizontal address generator;

A vertical shift register for selecting N addresses from among N + a vertical addresses generated in the vertical address generator;

Set an initial value among M + b horizontal addresses generated in the horizontal address generator to select M addresses, and set an initial value among N + a vertical addresses generated in the vertical address generator to set N addresses. A horizontal / vertical address selection control unit which transmits a control response signal to the horizontal shift register and the vertical shift register to select the control unit; And

And a horizontal / vertical address selector for selecting a signal output from the horizontal shift register and the vertical shift register.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of a preferred embodiment of the scrolling screen deformation apparatus according to the present invention.

In FIG. 1, the scrolling screen deformation apparatus according to the present invention includes a horizontal address storage unit 100, a horizontal address generator 102, a horizontal shift register 104, a vertical address storage unit 106, and a vertical address generator ( 108, a vertical shift register 110, a horizontal / vertical address selection control unit 112, and a horizontal / vertical address selection unit 114.

The horizontal address storage unit 100 stores M + b horizontal address values, and the vertical address storage unit 106 stores N + a vertical address values. The horizontal address generator 102 generates a horizontal address stored in the horizontal address storage unit 100, and the vertical address generator 108 generates a vertical address stored in the vertical address storage unit 106. The horizontal shift register 104 selects M addresses among the M + b horizontal addresses generated by the horizontal address generator 102, and the vertical shift register 110 is generated by the vertical address generator 108. N addresses are selected from among N + a vertical addresses. The horizontal / vertical address selection controller 112 selects M addresses by setting an initial value among the M + b horizontal addresses generated by the horizontal address generator 102 and generates the vertical address generator 108. The control response signal is transmitted to the horizontal shift register 104 and the vertical shift register 110 so that an initial value is set among the N + a vertical addresses. The horizontal / vertical address selector 114 selects signals output from the horizontal shift register 104 and the vertical shift register 110.

The configuration of the horizontal address storage unit 100 and the vertical address storage unit 106 will be described in detail with reference to FIGS. 2A through 2C.

FIG. 2A shows the horizontal address storage unit 100 of FIG. 1 applied to the present invention. The horizontal address storage unit 100 is set from address 0 to address M + b.

2b shows the vertical address storage 106 of FIG. The vertical address storage section 106 is set from address 0 to address N + a. Also, FIG. 2C is a diagram illustrating a relationship between the pixels of the monitor and the horizontal / vertical address storage units 100 and 106.

In FIG. 2C, reference numeral 200 denotes a monitor and 210 denotes horizontal / vertical address storage units 100 and 106. The monitor 200 has N x M pixels. The horizontal / vertical address storage unit 210 includes gray level information of all pixels of the monitor 200. The horizontal address storage unit 100 has a storage unit corresponding to the number of b more pixels than the number of horizontal pixels of the monitor 200. In addition, the vertical address storage unit 106 has a storage unit corresponding to the number of a pixels more than the number of vertical pixels of the monitor 200. That is, the memory corresponding to a × b is an unused area. On the other hand, the memory corresponding to unused axb is not fixed, but the range in (N + a) x (M + b) is a flexible area while maintaining the memory of axb.

Detailed description will be made with reference to FIGS. 3A to 3C for a proper understanding of FIG. 2C.

FIG. 3A shows that information of (N + a) x (M + b) is recorded in the horizontal / vertical address storage 210 of FIG. 2C. In FIG. 3B, information as much as N × M in FIG. 3A is displayed on the monitor 200 in FIG. 2C. That is, the hatched portions are portions that are not displayed on the monitor 200.

The portion displayed in the monitor 200 according to the address designation in the horizontal / vertical address storage unit 210 may be the same as in FIG. 3C.

A hatched portion in FIG. 3c is a portion that is not displayed on the monitor 200. Of course, the portion displayed on the monitor 200 corresponds to N × M.

That is, the part displayed on the monitor 200 is determined according to how the address of the horizontal / vertical address storage unit 210 of FIG. 3a is set.

4A shows an address setting on the monitor when it is displayed as shown in FIG. 3B, and FIG. 4B shows an address setting on the monitor when it is displayed as in FIG. 3C.

Then, when the address is set as shown in FIG. 5a, the screen may be modified as shown in FIG. 5b. In addition, if the address setting for screen modification with respect to FIG. 4B is readjusted as shown in FIG. 6A, the screen will be transformed and displayed as shown in FIG. 6B.

Specifying the address as described above can obtain the result of the screen transformation.

The scrolling screen deforming device as described above provides an effect of simply performing a screen deformation that is vertically or horizontally distorted according to addressing.
