Abstract

Apparatus and methods are disclosed for allowing smart phone users to “capture the moment” by allowing easy access to a camera application when a mobile device is in an above-lock (or locked) mode, while also preventing unauthorized access to other smart phone functionality. According to one embodiment of the disclosed technology, a method of operating a mobile device having an above-lock state and a below-lock state comprises receiving input data requesting invocation of an camera application when the mobile device is in the above-lock state and invoking the requested camera application on the device, where one or more functions of the requested application are unavailable as a result of the mobile device being in the above-lock state.

Claims

1. One or more computer-readable storage devices or memory storing computer-readable instructions that when executed by a computer cause the computer to perform a method of operating a mobile device having a plurality of authentication states, including an above-lock state and a below-lock state, the method comprising:

invoking an application on the mobile device in the above-lock state, wherein;

at least one or more of the following functions are available in the above-lock state;

capturing an image, providing an image capture settings menu, or toggling between a video capture mode and a still image capture mode, and

at least one or more of the following functions of the application are available to a user while the mobile device is in the below-lock state but are unavailable to the user of the mobile device while the mobile device is in the above-lock state;

deleting an image, sending an image, or uploading an image to a remote server;

based on receiving input data requesting one of the unavailable functions, presenting a user interface operable to change the state of the mobile device to the below-lock state;

receiving input data using the user interface;

based on the received input data, changing the state of the mobile device to the below-lock state; and

after the changing the state of the mobile device to the below-lock state, providing the requested application on the mobile device, unless a proximity sensor detects an object in proximity with the mobile device, wherein at least one of the previously unavailable functions is made available to the user of the mobile device.

2. The computer-readable storage devices or memory of claim 1, wherein the method further comprises:

capturing an image; and

after the capturing, determining the state of the mobile device, wherein;

if the state of the mobile device is the below-lock state, transmitting the image to a location remote from the mobile device; and

if the state of the mobile device is the above-lock state, not transmitting the image to a location remote from the mobile device.

3. The computer-readable storage devices or memory of claim 1, wherein the method further comprises waking the mobile device from a standby state based on receiving input data requesting invocation of the application.

4. The computer-readable storage devices or memory of claim 3, wherein the input data is received as a result of an image-capture button being depressed for a predefined duration.

5. The computer-readable storage devices or memory of claim 3, wherein the input data is received as a result of both an image-capture button press being detected and second input data being received after detection of the image-capture button press.

6. The computer-readable storage devices or memory of claim 3, wherein the input data is received as a result of an image-capture button being pressed concurrently with another button coupled to the mobile device.

7. The computer-readable storage devices or memory of claim 1, wherein the invoking the application further comprises evaluating a previously-stored user setting permitting the application to be invoked when the mobile device is in the locked state.

8. The computer-readable storage devices or memory of claim 1, further comprising providing haptic feedback when invoking the application.

9. The computer-readable storage devices or memory of claim 1, wherein the method further comprises evaluating both a proximity sensor and a light sensor coupled to the mobile device, and wherein the providing the application occurs unless the evaluating determines an object in proximity with the mobile device.

10. One or more computer-readable storage devices or memory storing computer-readable instructions that when executed by a computer cause the computer to perform a method of operating a mobile device having a plurality of authentication states, including an above-lock state and an below-lock state, the mobile device being coupled to a proximity sensor, the instructions comprising:

instructions for determining when the mobile device is in the above-lock state, and if so, presenting an unlock user interface;

instructions for evaluating the status of the proximity sensor to determine that an object is not in proximity with the mobile device by;

checking the status of the proximity sensor after the input module receives the input data,

preventing invocation of the unlock user interface if the evaluated status indicates that an object is in proximity with the apparatus, and

allowing invocation of the unlock user interface if the checked status indicates that an object is not in proximity with the apparatus;
