Method and system for configuring an imaging device for the reception of digital pulse recognition information
First Claim
1. A mobile device, comprising:
- an image sensor;
a processor coupled to the image sensor;
a memory; and
software in the memory to be run by the processor, wherein running of the software by the processor configures the mobile device to implement functions, including functions to;
determine that the mobile device is in a location enabled with light sources that generate modulated visible light signals;
in response to the determination, initialize parameter settings of the image sensor including locking an exposure setting of the image sensor to optimize the image sensor to receive the modulated visible light signals generated by the light sources;
capture using the image sensor according to the initialized image sensor parameter settings an image containing a representation of a modulated visible light signal generated by one of the light sources in the location; and
obtain information from the visible light signal generated by the one light signal by demodulating the representation of the modulated visible light signal contained in the captured image.

Abstract
In one aspect, the present disclosure relates to a method for configuring one or more imaging sensors of an imaging device to capture digital images for digital pulse recognition demodulation. In some embodiments, the method includes initializing one or more imaging sensors of the imaging device, determining a subset of the one or more imaging sensors to configure, setting a configuration for each of the one or more imaging sensors of the subset by defining a region of interest as a metering area for each of the one or more imaging sensors of the subset and automatically adjusting a setting for each of the one or more imaging sensors of the subset, and adjusting input parameters of a demodulation function based on a device profile of the imaging device. In some embodiments, the adjusted setting is locked to prevent further adjustment of the adjusted setting.
