Based on the received first detection information, the processing determination unit 13 determines whether an object is present within the range of the first detection range 51, that is, in a predetermined area in the space around the display device 3. It is determined (step ST2).

In step ST2, when the processing determination unit 13 determines that an object is not present in a predetermined area in the space around the display device 3 (step ST2 “NO”), the input control device 1 operates. finish.

In step ST2, when the processing determination unit 13 determines that an object is present in a predetermined area in the space around the display device 3 (step ST2 "YES"), the second reception unit 12 The second detection information is received from the second sensor 22 (step ST3). Next, the processing determination unit 13 determines whether an object approaches the operation unit 23 based on the received second detection information (step ST4).

In step ST4, when the processing determination unit 13 determines that the object approaches the operation unit 23 (step ST4 “YES”), the input control device 1 ends the operation.
In step ST4, when the processing determination unit 13 determines that the object is not approaching the operation unit 23 (step ST4 "NO"), the processing determination unit 13 performs processing corresponding to the detection of the object by the first sensor 21. The determination result information for instructing the output processing unit 31 to generate the control information is generated (step ST11). Thereafter, the processing determination unit 13 transmits the determination result information to the output processing unit 31 (step ST12), and the input control device 1 ends the operation.

As described above, the input control device 1 receives the first detection information from the first sensor 21 that detects the presence of an object in a predetermined area, and the operation unit 23.

The difference between FIG. 5 and FIG. 6 is that when the determination in step ST4 in FIG. 5 is “YES”, the process in step ST5 in FIG. 6 is added. Here, only processing of a portion having a difference from FIG. 5 will be described using FIG.

In step ST4, when the processing determination unit 13 determines that the object is approaching the operation unit 23 (step ST4 "YES"), the processing determination unit 13 detects the detection strength of the object in the first sensor 21, and It is determined whether the detection intensity of the second sensor 22 is stronger than the detection intensity of the first sensor 21 by comparing the detection intensity of the object in the two sensors 22 (step ST5).
In step ST5, when the processing determination unit 13 determines that the detection intensity of the second sensor 22 is stronger than the detection intensity of the first sensor 21 (step ST5 “YES”), the process determination unit 13 causes the user to operate It is determined that it is going to operate the unit 23, and the input control device 1 ends the operation.
In step ST5, when the process determination unit 13 determines that the detection intensity of the second sensor 22 is not stronger than the detection intensity of the first sensor 21 (step ST5 “NO”), the process determination unit 13 determines whether The process after step ST11 is performed.

As described above, the processing determination unit 13 compares the detection intensity of the object in the first sensor 21 with the detection intensity of the object in the second sensor 22, so that the input control device 1 detects the object by the first sensor 21. The determination as to whether or not to perform the process corresponding to the detection can be made more accurately.

Further, in the modification of the first embodiment, in addition to the processing of the first embodiment described above, the processing determination unit 13 determines the detection time of the object in the first sensor 21 and the detection time of the object in the second sensor 22. A process of comparing the detection time is added.
In this modification, in the determination process of step ST5 performed by the process determination unit 13, the time at which the second sensor 22 detects an object from the time at which the process determination unit 13 detects an object at the first sensor 21 This is realized by changing to a process of determining whether or not is ahead. In this modification, the detection times of the objects in the first sensor 21 and the second sensor 22 are compared, but even if the lengths of the detection times of the objects in the first sensor 21 and the second sensor 22 are compared good.
