Problems solved by technology

In this case, there is a concern that the touch panel device after performing the calibration process recognizes the state where the hand touches the touch panel during the calibration process as a non-contact state, so even if the hand is in the calibration process The touch operation is performed on the touched part, and the touch operation cannot be recognized

Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] figure 1 It is a figure which shows the structural example of the endoscope system to which the touch panel apparatus which concerns on one Embodiment of this invention is applied. Further, this endoscope system is a system used for endoscopy or the like in a medical institution (for example, a hospital).

[0024] like figure 1 As shown, the endoscope system 1 includes an endoscope (or a camera) 10 , a video processor (signal processing device) 20 , and a monitor 30 , and the video processor 20 is connected to the endoscope 10 and the monitor 30 .

[0025] The endoscope 10 includes an imaging unit 101 that captures the inside of a patient's body cavity, and outputs an image signal obtained by the imaging of the imaging unit 101 to the video processor 20 .

[0026] The video processor 20 includes a signal processing unit 201, a power source SW (switch) 202, a...

Abstract

The touch panel device includes: a capacitive touch panel; and a calibration execution unit that executes a first calibration process for performing a detection threshold value for a touch operation on the touch panel after power supply from a power source is started. adjustment of the reference potential; a touch operation detection section capable of detecting a touch operation in the touch panel after the first calibration process is completed; and a touch operation monitoring section which monitors the touch operation detection after the first calibration process is completed The detection of the touch operation in the part, when the first touch operation is detected by the touch operation detection part, instructs the calibration execution part to execute the second calibration process for adjusting the reference potential, wherein the calibration execution part is based on the touch operation monitoring part Instructs to execute the second calibration process.

Description

technical field [0001] The present invention relates to a touch panel device including an electrostatic capacitance type touch panel and a processing method of the touch panel device. Background technique [0002] Conventionally, it is known that, in an electrostatic capacitance type touch panel, the sensitivity of the touch panel changes according to a change in the surrounding environment (for example, temperature) used, or the like. Therefore, in a touch panel device including an electrostatic capacitance type touch panel, calibration processing for correcting the sensitivity of the touch panel is performed, for example, when the power is turned on (at the time of startup). In this calibration process, adjustment of a reference potential that becomes a detection threshold value of a touch operation on the touch panel, and the like are performed. [0003] The calibration process is premised on a non-contact state in which nothing touches the touch panel, but the calibrati...
