Electronic device for scene evaluation and image projection onto non-planar screens
View Patent ↗An electronic device may have one or more imaging sensors. The imaging sensors may be used in combination with an optional mechanical gesture to analyze the lighting conditions of the environment around the electronic device. The electronic device may set auto-exposure, auto-white balance, and auto-focus settings based on the analysis. The electronic device may include a shaped display. The imaging sensors may be used in calibration of a projector for the shaped display and may be used in sending touch inputs associated with the shaped display. The electronic device may be able to capture a photograph during video capture. The electronic device may generate a display screen that identifies which portions of the scene being imaged correspond to the video and which portions correspond to the photograph.
1. A method, comprising:
with an electronic device, prompting a user to perform a mechanical gesture with the electronic device, wherein prompting the user to perform the mechanical gesture with the electronic device comprises prompting the user to move the electronic device along a curved path while holding the electronic device at arm's length;
with at least one camera sensor in the electronic device and during the particular mechanical gesture, capturing image data of an environment around the electronic device;
with image processing circuitry in the electronic device, identifying lighting characteristics of the environment based on the image data;
with circuitry in the electronic device, determining imaging settings based on the identified lighting characteristics; and
with the at least one camera sensor, capturing an image using the determined imaging settings.
2. The method defined in claim 1 wherein the lighting characteristics comprises at least one lighting characteristic selected from the group consisting of:
a location of a light source, a color temperature of the light source, a color profile of the light source, an intensity of the light source, and a relative velocity of the light source.
3. The method defined in claim 1 wherein the determined imaging settings comprise at least one imaging setting selected from the group consisting of: an auto-white balance setting, an auto-exposure setting, and an auto-focus setting.
4. The method defined in claim 1 wherein prompting the user to perform the mechanical gesture comprises:
with the electronic device, prompting the user to rotate the electronic device between 180 and 360 degrees.
5. The method defined in claim 1 comprising:
with location sensing circuitry, determining a location of the electronic device; and
storing the determined location together with at least one of the captured image data, identified lighting characteristics, and determined imaging settings in nonvolatile storage in the electronic device.
6. The method defined in claim 5 wherein the location sensing circuitry comprises global positioning system circuitry.
