Title:
PRECISION LUXMETER METHODS FOR DIGITAL CAMERAS TO QUANTIFY COLORS IN UNCONTROLLED LIGHTING ENVIRONMENTS
Document Type and Number:
WIPO Patent Application WO/2016/025935
Kind Code:
A3
Abstract:
In one embodiment, a diagnostic system for biological samples is disclosed. The diagnostic system includes a diagnostic instrument, and a portable electronic device. The diagnostic instrument has a reference color bar and a plurality of chemical test pads to receive a biological sample. The portable electronic device includes a digital camera to capture a digital image of the diagnostic instrument in uncontrolled lightning environments, a sensor to capture illuminance of a surface of the diagnostic instrument, a processor coupled to the digital camera and sensor to receive the digital image and the illuminance, and a storage device coupled to the processor. The storage device stores instructions for execution by the processor to process the digital image and the illuminance, to normalize colors of the plurality of chemical test pads and determine diagnostic test results in response to quantification of color changes in the chemical test pads.
