Multi-dimensional image detection apparatus

摘要

According to the present invention, a multi-dimensional image detection apparatus includes a touch surface, at least one two-vision image sensing module located proximally to the touch surface, and a control module coupled to the image sensing module. The multiple-dimensional image detection apparatus can detect a foreign object's image with at least two different dimensional modes. A method of multiple-dimensional image detection is also disclosed by reading the image data acquired by the image sensing module and comparing with a pre-stored background data to determine detecting the foreign object under a predetermined dimensional mode.

1. A multi-dimensional image detection apparatus, said apparatus comprising:
a touch surface on a substrate; a first image detection module comprising a first image sensing module and a first light screen; a second image detection module comprising a second image sensing module and a second light screen; at least one light source for emitting a first predetermined light spectrum being infrared light; wherein the first image detection module and the second image detection module located proximally to the touch surface on the substrate for capturing image data based on a received light spectrum, wherein each of the first light screen and second light screen having a first region and a second region, and wherein a first region of each of the first light screen and the second light screen permits only the first predetermined light spectrum to pass through, and a second region of each of the first light screen and the second light screen permits a second predetermined light spectrum to pass through, the second predetermined light spectrum being visible light; and a control module coupled to each of the first image sensing module and second image sensing module, wherein the control module: processes at least a portion of the image data captured by at least one of the first image sensing module and the second image sensing module; determines a location of a foreign object within a detection region based on the processed image data in comparison; and switches, automatically, a mode of operation of the first and second image sensing modules between a first mode of operation and a second mode of operation based on the determined location of the foreign object relative to the touch surface, wherein the location of the foreign object is determined based on the first predetermined light spectrum when operating in the first mode of operation, and wherein the location of the foreign object is determined based on the second predetermined light spectrum when operating in the second mode of operation.
