[First Embodiment]

  Next, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the input device according to the first embodiment of the present invention. Referring to FIG. 1, image information is supplied to a patch panel 16, a display device 11 such as a CRT (Cathode Ray Tube) or a liquid crystal display device, a display control unit 12 that controls the display device 11, and the display control unit 12. Data input from the video memory (VRAM) 13 and the patch panel 16 is input to a CPU (Central Processing Unit) 15, and data (image information) output from the CPU 15 is output to the video memory (VRAM) 13. A configuration including an interface circuit 14 and a CPU 15 is shown.

  The display control unit 12 includes a CRT controller or an LCD controller that takes out image information from a video memory (VRAM) 13 and controls the display device 11.

  A video memory (VRAM) 13 holds image information sent from the CPU 15 via the interface circuit 14 and supplies the image information to the CRT controller 12.

  The CPU 15 calculates the size (contact area) of the contacted object based on the data (input position) input from the touch panel 16, and uses the value to calculate the contact area calculating means and the pointer. It functions as a position adjusting means. The processing contents as the contact area calculating means and the pointer position adjusting means can be realized by a program that causes the CPU to perform the operations described later.

  The touch panel 16 is disposed on the display screen of the display device 11 and inputs data to the CPU 15 through the interface circuit 14. As the touch panel 16 capable of detecting multi-point input positions so that the contact area can be calculated by the CPU 15, a projection capacitive type can be used. The projected capacitive touch panel has a large number of electrode patterns made of transparent electrode technology on a substrate such as glass or plastic, and measures the ratio of the amount of current generated by multiple electrode patterns near the contact position. Thus, the input position and its size (contact area) can be accurately determined. In addition, any method other than the above-described projected capacitance method can be adopted as long as it is a method capable of detecting multi-point input positions or contact areas with an accuracy sufficient to implement the present invention.

  Subsequently, the operation of the first exemplary embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a flowchart showing the operation of the input device according to the first embodiment of the present invention.

  Referring to FIG. 2, first, when the processing operation starts, the CPU 15 determines whether any touched object is touching the touch panel 16 (step S1).

  Here, when some touched object is touching the touch panel 16, the size (contact area) of the touched object is calculated from the data input from the touch panel 16, and the threshold value is determined by assuming the fingertip. It is determined whether it is larger (step S2). As the threshold value, a value corrected by the user may be used.

  As a result of the comparison with the threshold value, when it is determined that the size (contact area) of the contacted object is larger than the threshold value (Yes in step S2), the CPU 15 determines that the contacted object is a finger. Determination is made, and the coordinate value of the pointer is set at a position separated from the touch position (center of the contact position) by the distance H (for example, the upper right direction of the touch position, the position of the distance H) (step S3).

  On the other hand, when it is determined that the size (contact area) of the contacted object is equal to or smaller than the threshold value (No in step S2), the CPU 15 determines that the contacted object has a small contact surface such as a touch pen. Judgment is made and the coordinate value of the pointer is set at the touch position (at or near the contact position) (step S3).

  The CPU 15 displays a pointer at the coordinate position set in step 3 or step 4 (step S5).

  The above process is continued until the position input process is completed by a process confirmation operation or the like (to step S1).

  According to the present invention that operates as described above, for example, as shown in FIG. 3, when a touch is performed with a finger, the pointer P is located at a position that is a distance H from the touch position, that is, a position that is not hidden by the finger. Can be displayed.

  Also, as shown in FIG. 4, when a touch is performed with a pen or the like, the pointer P can be displayed immediately under or near the touch position. As the distance H at this time, a zero value or a value considering the thickness of a standard touch pen can be used.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments may be made without departing from the basic technical idea of the present invention. Can be added.

  For example, in the above-described embodiment, when the contact area is larger than a predetermined threshold value, the pointer is displayed at a position separated by the distance H from the touch position. It is also possible to increase the distance H as the size increases. In this way, for example, a position pointer that is not hidden by the finger but is closest to the touched position can be displayed depending on whether the user touches with the thumb or the little finger. In addition, when it is assumed that an object other than a finger is used for designating the position on the screen, the threshold value based on the average area when each object touches the screen, You may set each combination with the distance to apply.

  Further, in the above-described embodiment, it has been described that the pointer is displayed at the touch position (center of the contact position or very close to it) when the contact area is equal to or smaller than the predetermined threshold value. May be shifted to a trajectory drawing mode in which only the trajectory associated with the movement of the pen tip is drawn while the pointer is not displayed. In this way, it is possible to input a diagram or the like as if drawing with the pen tip.
