Method for detecting a response of each probe zone on a test strip
First Claim
1. A method, comprising:
- providing a test strip having a background and a pattern displayed thereon, the pattern occurring in response to a tested solution contacting a first region of the test strip, the pattern having a plurality of test lines that each correspond to a probe zone configured to indicate the presence or absence of a corresponding substance in the tested solution;
capturing an image of the test strip using a scanning device;
selecting at least one scan line from the image, the scan line intersecting image lines of the pattern in the captured image;
identifying pixel positions located at intersections of the scan line and the image lines of the pattern in the captured image;
selecting a reference pixel position associated with an edge of the test strip; and
correlating each of the identified pixel positions with a particular one of the probe zones using the reference pixel position and a preset sequence of the probe zones.

Abstract
A method for detecting a response of each probe zone on a test strip is provided. The present method includes providing a test strip having a color pattern displayed thereon. The color pattern occurs in response to a tested solution contacting with the test strip and including a plurality of color lines displayed in sequence from a bottom portion of the test strip to a top portion thereof. The site of each color line represents a probe zone of the test strip. Capturing a whole image of the test strip and selecting at least one scan line perpendicular to the image of the color lines therefrom. Setting a pixel position of the scan line having a minimum pixel value corresponding to a bottom edge of the test strip and using the pixel position as a reference to identify respective pixel positions of the color lines on the scan line so as to identify the image positions thereof on the whole image. A response of each probe zone of the test strip related to a gray level of a corresponding image position is thus obtained.
