Abstract

The automatic zooming front-camera two-dimensional or QR code sensor without on-screen two-dimensional or QR code display has special characteristics in that the front camera captures a partial image of the QR code (5) and sends information for processing by a QR code sensor program (4) in order to detect the target image and conduct QR code image (5) analysis and instruct the front camera to automatically zoom in and out to clearly capture the QR code image (5) and decode the QR code (5) as relevant information (6).

Description

AUTOMATIC ZOOMING FRONT-CAMERA TWO-DIMENSIONAL QR CODE SENSOR WITHOUT ON-SCREEN TWO-DIMENSIONAL OR QR CODE DISPLAY
Background of Relevant Arts or Science
Reading of QR codes via front cameras with the use of modern smart phones or tablets requires that the front camera be turned on. The camera can capture an image positioned in an area with limited space. As a result, the user needs to position their smart phone or tablet in such a way that it can capture the entire QR code. Furthermore, the distance between the front camera and QR code needs to meet specifications in order for the front camera to capture clear images of the QR code that allows the smart phone or tablet to decode the QR code. The drawback is that the user is required to set the area and spacing between the front camera and QR code based on specifications, which is inconvenient, slow, complicated, outdated and forces the user to keep glancing at the display throughout the entire QR code reading.
In this invention, a concept arose to construct an automatic zooming front-camera two- dimensional or QR code sensor without on-screen two-dimensional or QR code display with characteristics in which smart phones or tablets can have installed a QR code sensor program with the following modes:
Mode 1 - The front camera captures a partial image of the QR code and sends information for processing by the QR code sensor program in order to detect the target image and conduct an analysis to confirm that it is a QR code image. Mode 2 - The QR code sensor program that provided the QR code image analysis will instruct the front camera to zoom in and out automatically in order to clearly capture the QR code image and decode the QR code as relevant data.
The results of the QR code image capture are not shown on the display modes of smart phones or tablets. Displays will use related programs to decode the QR code currently in use. Invention Characteristics and Objectives
The automatic zooming front-camera two-dimensional or QR code sensor without onscreen two-dimensional or QR code display with characteristics in which smart phones or tablets can have a QR code sensor program installed with the following modes:
Mode 1 - The front camera captures a partial image of the QR code and sends information for processing by the QR code sensor program in order to know of the target image and conduct an analysis to confirm that it is a QR code image.
Mode 2 - The QR code sensor program providing the QR code image analysis will instruct the front camera to zoom in and out automatically in order to clearly capture the QR code image and decode the QR code as relevant data.
The results of the QR code image capture are not shown on the display modes of smart phones or tablets. Displays will be of the usage of related programs to decoding the QR code currently in use.
This invention is intended to provide an automatic zooming front-camera two- dimensional or QR code sensor without on-screen two-dimensional or QR code display in order to facilitate, accelerate and modernize without the necessity to stare at the display throughout the entire time of reading a QR code.
Branch of Science Associated with the Invention
Engineering as related to the automatic zooming front-camera two-dimensional or QR code sensor without on-screen two-dimensional or QR code display.
Full Disclosure of the Invention
Figure 1 shows the schematics of the automatic zooming front-camera two-dimensional or QR code sensor without on-screen two-dimensional or QR code display with characteristics in which smart phones or tablets (3) can have installed the QR code sensor program (4) by the modes as follows: Mode 1 - (1) The front camera would capture a partial image of the QR code (5) and send information for processing by the QR code sensor program (4) in order to know of the target image and conduct an analysis to confirm that it is a QR code image (5).
Mode 2 - (2) The QR code sensor program (4) that provided the QR code image (5) analysis will instruct the front camera to zoom in and out automatically in order to clearly capture the QR code image (5) and decode the QR code (5) as relevant data (6) such as looking up IDs of persons or IDs of goods or services.
The results of the QR code image capture are not shown on the display modes of smart phones or tablets (3). Displays will use related programs to decode the QR code (5) currently in use such as the display of the LINE chat program.
