Abstract
Described are techniques that guarantee the best opportunity for a camera to capture an image with an acceptable level of quality. Too frequently, images captured with mobile devices such as smartphones and tablet computers fail to capture images of sufficient quality for optical character recognition, for example. Image capture is allowed only after successfully completing a check of sufficient stabilization and focusing of the camera. A variety of sensors may be used to check stability including gyrometers, proximity sensors, accelerometers, and light sensors.
Claims23
A method for capturing an image with a camera component of an electronic device, the method comprising:
- (1) sensing a signal associated with capturing an image with the camera of electronic device;
- (2) sensing a sensor signal from a sensor associated with the device;
- (3) identifying a state of relative stabilization of the electronic device based on said sensed sensor signal;
- (4) checking an indication of focusing of the camera component in the state of relative stabilization of the device;
- and
- (5) triggering capture of the image with the camera component of the electronic device.
A method for capturing an image with a camera of a mobile electronic device, the method comprising:
- (1) sensing a signal associated with capturing an image with the camera;
- (2) monitoring a signal from a sensor associated with the device;
- (3) identifying a period of relative stability greater than a time T from the recording of the signal from the sensor that indicates an interval of relative stability (“first period”);
- (4) performing an automatic focusing function of the camera in the period of relative stability;
- and
- (4) triggering capture of an image with the camera.
An electronic device for capturing images, the device comprising:
- a sensor capable of generating a signal related to motion of the electronic device;
- an image capturing component;
- a processor;
- a memory electronically in communication with the sensor, the image capturing component, and the processor, wherein the memory is configured with instructions to perform a method, the method including:
- detecting a signal indicative of a trigger to capture an image with said image capturing component;
- monitoring a signal associated with the sensor;
- identifying a period of relative stability greater than a time from the monitoring of the signal associated with the sensor that indicates an interval of relative stability (“first period”);
- triggering capture of an image with the image capturing component;
- and
- storing a representation of the image in the memory.
