Problems solved by technology

Furthermore, in order to recognize the shape of the hand, processing for distinguishing the background image from the image of the hand is performed, but if the background image also contains texture similar to the hand, the shape (region) of the hand cannot be accurately extracted, and an error Possibility of recognizing gestures is higher

Embodiment approach 2

[0213] In the above-mentioned embodiment, when the temperature sensor chip 6 has a structure in which 4×4 infrared sensors are arranged, the gesture recognition is described in which a gesture is recognized by processing 4×4 temperature information obtained from these infrared sensors. The structure of device 1.

[0214] However, the configuration of the gesture recognition device 1 of the present invention is not limited to the above. The arrangement of the infrared sensors of the temperature sensor chip 6 can be configured in any pattern. For example, the infrared sensor may be arranged not only in a square shape but also in a rectangular or circular shape. In addition, it is also possible to increase the number of infrared sensors arranged so that the temperature sensor chip 6 has a high resolution. According to this configuration, it is possible to detect a plurality of objects (for example, the movement of both hands) only by using temperature information, or to accurat...

Deformed example 2

[0251] In the above-mentioned embodiments, the case where the sensor unit 2 and the gesture recognition device 1 (smartphone 100 ) are integrally configured has been described, but the configuration of the gesture recognition device 1 of the present invention is not limited thereto.

[0252] For example, a configuration in which the sensor unit 2 is provided at a distance from the gesture recognition device 1 and the gesture recognition device 1 acquires a detection signal from the sensor unit 2 using an appropriate communication means is also included in the present invention. That is, the gesture recognition device 1 does not need to include the sensor unit 2 , and in this case, it only needs to include an appropriate communication means for acquiring a detection signal from the sensor unit 2 .

Abstract

A non-contact input function in which high-speed processing and high accuracy are achieved irrespective of brightness of a service space is implemented, A gesture recognition apparatus (1) of the invention includes a temperature sensor chip (6) in which plural infrared sensors are arranged, a change amount calculator (32) that specifies a change region where a temperature change is generated as a region indicating a hand based on a temperature detected by each infrared sensor of the temperature sensor chip (6); and a gesture recognition unit (34) that specifies a movement locus of the change region specified by the change amount calculator (32) and recognizes a gesture of the hand.

Description

technical field [0001] The present invention relates to a gesture recognition device for recognizing a gesture, a gesture recognition method, a control program, and a recording medium. Background technique [0002] Conventionally, input functions to electronic devices such as mobile phones, PDAs (Personal Digital Assistants), televisions, video playback devices, personal computers, and digital cameras have been realized in various forms. As a method of realizing the input function, first, there is a method of bringing an object (finger, stylus, etc.) into contact with an input device (button, touch panel) to perform input (for example, Patent Documents 1, 2, etc.). Second, there is a method of making an input device (camera, etc.) recognize an object to input to an input device or an electronic device in a non-contact manner (for example, Patent Document 3, etc.). [0003] In the first contact-type input realization method, various inputs can be reliably and instantaneously...
