Problems solved by technology
[0004] However, the problem with such an operation method is that since the active light source 110 and the sensing device 120 only detect light and shadow changes intermittently in the standby mode, if the light and shadow changes caused by hand movements cannot be detected during this period (for example : the hand movement is too fast), it takes a long time for the sensing system 100 to return to the normal operation state and perform gesture detection
This is because in the standby mode, the operating frequency of the sensing system 100 is low, and it is easy to miss the movement of the user's hand.
In this way, when the user wants to activate the sensing system again in standby mode, there will be a noticeable delay

Embodiment Construction
[0024] Please refer to image 3 , which is a schematic structural diagram of an embodiment of the electronic device of the present invention. As shown in the figure, the electronic device 300 of the present invention includes: a sensing system 310 , a sensing device 320 and a control unit 330 . Wherein, the sensing system 310 may be a gesture detection device, and includes a sensing device 315 for selectively detecting an object to be detected (eg, a hand) to generate a detection result SR_1 . The detection result SR_1 can indicate the motion of the object to be detected. The sensing device 315 is mainly composed of a sensor array and related computing and control circuits. The sensing device 320 is used for selectively detecting the object to be detected to generate a detection result SR_2. The purpose of the detection result SR_2 is to indicate whether the object to be detected is in a specific spatial range L (ie, the effective sensing range of the sensing system 310 ). ...

The invention provides a sensor array, a method for controlling a sensing device and a related electronic device. The method can lower power consumption of a gesture sensing device. Mainly an auxiliary sensing device is used for sensing if an object to be sensed is located within an effective sensing range of a gesture sensor, and then operation states and power consumption of the gesture sensing device and the auxiliary sensing device are determined. Before the auxiliary sensing device senses that the object to be sensed is located within the effective sensing range or before the object to be sensed moves, the gesture sensing device can be made to operate in a low-power-consumption operation state, and power consumption of the gesture sensing device is lowered.
Description
technical field [0001] The present invention relates to an image sensor, and more particularly to a method for reducing power consumption of a gesture detector, an electronic device and a related sensor array. Background technique [0002] At present, gesture detection devices are widely used in various fields, providing an innovative and intuitive human-computer interaction method, which mainly detects the user's hand movements and sends corresponding control commands to the user interface. Take control. Generally speaking, existing sensing systems for gesture detection include figure 1 The architecture shown. Wherein, an active light source 110 periodically illuminates the hand, and then, the sensing device 120 correspondingly periodically detects the light and shadow changes generated after the illumination. The computing circuit inside the sensing device 120 will determine whether the hand movement corresponds to a specific gesture pattern, and further generate contro...
