Problems solved by technology

[0003] However, when the general gesture recognition system is used to detect motion information, such as: gesture motion, proximity judgment or even other object sensing, only single-function object detection can be performed, such as: close-range gesture image judgment or far Gesture image of distance
That is to say, when it is possible to detect close-range gesture images, it cannot detect long-distance gesture images, and vice versa

[0047] see Figure 6 and Figure 7 and cooperate Figure 5A ~ Figure 5C as shown, Figure 6 is a functional block diagram of detecting an object to be tested according to the third embodiment of the present invention, Figure 7 It is a schematic diagram of the photosensitive array 1a of the image sensor A according to the third embodiment of the present invention. The third embodiment of the present invention provides an image sensor A, including a photosensitive array 1 a and a processing unit 2 . The photosensitive array 1a includes a plurality of first photosensitive pixels 14 and a plurality of second photosensitive pixels 15, the first photosensitive pixels 14 sense light in a visible wavelength range, and the second photosensitive pixels 15 sense light in an invisible wavelength range, and The number of first photosensitive pixels 14 is greater than the number of second photosensitive pixels 15. The reason is that what the first photosensitive pixels 14 sense is an i...

Abstract

The invention provides a method for detecting the action information, a light sensing array, and an image sensor. The method comprises the following steps: providing the light sensing array which is used for detecting an image of a to-be-detected object in a first distance range or a second distance range, wherein the light sensing array comprises a plurality of invisible light sensing pixels anda plurality of visible light sensing pixels; employing the invisible light sensing pixels for image detection in the first distance range, so as to obtain a plurality of invisible light images; employing the visible light sensing pixels for image detection in the second distance range, so as to obtain a plurality of visible light images; processing the invisible and visible light sensing images through a processing unit, so as to obtain the action information of the to-be-detected object. The method solves a problem that a gesture recognition system just can achieve the detection of a short-distance gesture image or a long-distance gesture image and cannot achieve the simultaneous detection of the short-distance and long-distance gesture images when the gesture recognition system is used for detecting gesture images.

Description

technical field [0001] The invention relates to a method for detecting motion information and a photosensitive array, in particular to a method capable of simultaneously detecting motion information in a range of far and near distances, a photosensitive array and an image sensor. Background technique [0002] Generally, touch methods are used to control electronic products, such as remote controllers, mice, and touch screens. In recent years, in order to improve the convenience of human-computer interaction, gesture recognition systems or voice control systems in non-touch control systems have been introduced into game consoles, smart TVs, smart phones, tablet devices, and automotive electronics. in consumer electronics. The development of the gesture recognition system, in addition to making the machine-machine interaction more unrestricted, also provides users with a more convenient and higher-quality lifestyle. [0003] However, when the general gesture recognition syst...
