[Industrial application field]

The present invention relates to a mask pattern input device that generates and inputs a mask pattern that specifies a processing target area of an image.

When an operator performs image conversation processing with an image display device, he inputs a boundary line image between the processing target area and the non-processing area of the image, that is, a mask pattern, to define the processing area. May be limited.

[Conventional technology]

Conventionally, there are two methods for inputting a mask pattern: a method in which a mask pattern is generated on a host computer and the like and downloaded to a display device, and a method in which the mask pattern is input continuously from a tablet or the like.

When inputting a mask pattern using a tablet, there is usually only one coordinate reading device, so the coordinate reading device is moved along the desired mask pattern and coordinate points are continuously input.

[Problem to be solved by the invention]

This conventional method, i.e., the former method in which mask patterns are generated using a host computer, etc., makes it difficult to create flexible mask patterns. The problem was that I had to type it in.

The present invention was created in view of the above points, and an object of the present invention is to provide an apparatus that can freely shape a mask pattern and easily perform the process manually.

[Means to solve the problem]

In order to achieve the above-mentioned objects, a mask pattern setting section includes a sensing element arranged on a freely bendable annular member, a coordinate point signal generation circuit generates a coordinate point signal and scans a coordinate input device; An input signal control circuit that generates coordinate point data from the signals of the sensing elements of the mask pattern setting section, an input memory that stores the coordinate point data, and a mask pattern generation circuit that generates mask pattern data by performing spline interpolation between the coordinate points. and a mask pattern memory to constitute a mask pattern input device.

[For production]

The mask pattern setting section is shaped like a flexible ruler, so
Shape along the desired mask pattern on the coordinate point input device.

The sensing element of the mask pattern setting unit senses the coordinate point signal scanned by the coordinate point signal generation circuit, and the input signal control circuit generates coordinate point data of the sensing element based on the coordinate point signal of the sensing element.

Then, the coordinate point data is stored in the input memory, and the mask pattern generation circuit generates coordinate points between the coordinate points stored in the input memory by a predetermined interpolation method, thereby creating continuous closed curve mask pattern data.

The mask pattern data is stored in a mask pattern memory and defines an area to be processed in the image by subsequent means.

〔Example〕

FIG. 1 is a block diagram showing the configuration of an embodiment of the mask pattern input device of the present invention, and FIG. 2 is a diagram showing the external appearance of the mask pattern input device of the present invention.

In the mask pattern input device, as shown in FIG. 2, a coordinate point signal generation circuit 1 generates a coordinate point signal and scans a coordinate point signal Z.

A flexible ruler-shaped annular member M whose shape can be freely set is placed on this coordinate input device Z.

A mask pattern setting section 2 in which sensing elements S for sensing coordinate point signals are arranged at predetermined intervals is installed on the annular member M.

Then, the operator shapes the annular member M into the shape of a desired mask pattern.

The sensing element S of the mask pattern setting unit 2 corresponds to the signal attribute of the coordinate point signal. For example, if the coordinate point signal is an electric field signal, an electrostatic sensor is used, and if the coordinate point signal is a magnetic field signal, a magnetic sensor is used.

The coordinate point signal generation circuit 1 scans the coordinate points using, for example, an electric field signal.

The electrostatic sensor of the mask pattern setting section 2 senses an electric field signal scanning its own coordinate point, and sends the signal to the input signal control circuit 2.
sends a sensing signal to.

The input signal control circuit 3 identifies the coordinates of the electrostatic sensor from the scanning coordinate point of the electric field signal and the time point when the sensing signal is generated, and stores the coordinate point data in the input memory 4.

In this way, the coordinate point data of the electrostatic sensor of the mask pattern setting section 2 stored in the input memory 4 is read out to the mask pattern generation circuit 5.

Then, coordinate point data is interpolated and set so as to be linearly continuous between adjacent coordinate point data by spline interpolation.

For example, in the quadratic curve interpolation method, a quadratic curve connecting a plurality of adjacent coordinate points is approximately set using the method of least squares, and coordinate points on the curve are interpolated to generate mask pattern data.

The mask pattern data generated by the mask pattern generation circuit 5 is stored in the mask pattern memory 6, and becomes processing data to be performed in a subsequent stage circuit (not shown).

〔Effect of the invention〕

By incorporating a plurality of coordinate input elements into a flexible ruler and controlling input signals, it is possible to perform mask-back input without operator operations.
