Claims

A user interface;
A camera for acquiring an image of a scene including light from a light source;
And the processing module
A device for detecting an encoded light component , comprising:
The light from the light source, the modulated with encoded optical component, wherein the camera includes an image sensor is divided into a plurality of lines, thereby to obtain the image, in the order in time when the line is different Exposed, the imaging element defines a plane;
The processing module detects an orientation angle of the light source projected on the plane of the image sensor with respect to the line of the image sensor, and based on this, a footprint of light from the light source is the image. Determining a target reorientation of the device covering an increased number of the lines at
The device, wherein the user interface outputs an indication of the target reorientation to the user to guide the user to rotate the device to perform the target reorientation.

The target redirection is required for the footprint of light from the light source to cover the maximum number of the lines that can be covered by the footprint at the current distance of the device from the light source. The device of claim 1.

The device of claim 1 or 2, wherein the user interface includes a display and the acquired image is not displayed on the display.

The device according to claim 1, wherein the device is one of a portable device, a smartphone, or a tablet.

The device according to claim 1, wherein the user interface includes a display, and the indication of the target reorientation is output to the user via the display.

The display is
Sentence shown on the display, wherein the reading of the sentence is oriented on the display such that the user needs to rotate the device to the target reorientation And / or a graphic on the display, wherein viewing the graphic directly requires the user to rotate the device to the target reorientation to be oriented on the screen. The device of claim 5, comprising at least one of the following:

7. A device according to claim 5 or 6, wherein the display includes an arrow on the display indicating in which direction the device should be rotated to achieve the target reorientation.

The display is based on the orientation angle of the device relative to the target reorienting, the include varying the color and / or intensity on the display, according to claim 5, 6 or 7 device.

The color that is green indicates that the device is rotated in a direction that approaches the target reorientation, and the color that is red indicates that the device is rotated in a direction away from the target reorientation. 9. The device of claim 8, shown.

Wherein the display includes displaying a metric to measure the orientation angle of the device relative to the target reorientation, according to any one of claims 1 to 9 device.

The metric represents the current number of lines of the imager covered by the footprint relative to the maximum number of lines that can be covered by the footprint at the current distance of the device from the light source. Device described in.

The said processing module contains the image processing module which performs the said detection by detecting the orientation of the said light source as an external appearance in the said image acquired with respect to the said line of the said image pick-up element. Device described in.

The processing module is configured to measure the absolute orientation of the device measured using an orientation sensor, the position of the device measured using a positioning system, and a predetermined knowledge of the position and the absolute orientation of the light source. 13. The detection is performed based on a mapping of: and the processing module thus determines a relative orientation from the absolute orientation of the device compared to the absolute orientation of the light source. Device described in.

An image pickup device comprising: acquiring a scene image including light from a light source using a device camera, wherein the light from the light source is modulated with an encoded light component, and the camera is divided into a plurality of lines Whereby the lines are exposed in sequence at different times to obtain the image, and the imaging element defines a plane;
Detecting the orientation of the light source projected on the plane of the image sensor relative to the line of the image sensor;
Based on the detection, a footprint of the light from the light source determines a target reorientation of the device that covers an increased number of the lines in the image;
Outputting the indication of the target reorientation to a user via a user interface of the device.

Code embodied on at least one computer-readable storage medium, retrieved from the storage medium and / or downloaded via a communication network; and
An operation of acquiring an image of a scene including light from a light source using the camera of the device, wherein the light from the light source is modulated with an encoded light component, and the camera is divided into a plurality of lines. An operation comprising: an element, whereby the lines are exposed in sequence at different times to acquire the image, and the imaging element defines a plane;
Detecting the orientation of the light source projected on the plane of the image sensor with respect to the line of the image sensor;
Based on the detection, an operation in which a footprint of light from the light source determines a target reorientation of the device that covers an increased number of the lines in the image;
A computer program comprising the code executed on the device to perform an operation to output an indication of the target reorientation to a user via a user interface of the device.
