Abstract
Capturing a target image includes activating a first image sensor for capturing the target image. A sequence of images is captured with a second image sensor while the first image sensor remains activated. A determination is made as to whether the sequence of images captured by the second image sensor includes a shutter gesture while the first image sensor remains activated. If a shutter gesture is included in the sequence of images captured by the second image sensor, the first image sensor captures the target image in response.
Claims15
A method of initiating an image capture of a target image with an image capturing device without initiating the image capture by physically contacting the image capturing device, the method comprising:
- activating a first image sensor for capturing the target image;
- capturing a sequence of images with a second image sensor different from the first image sensor, wherein the first image sensor and the second image sensor are included in the image capturing device and wherein each image in the sequence of images is captured with only a portion of pixels in sectors of the second image sensor;
- determining if the sequence of images captured with the second image sensor includes a shutter gesture performed by a user;
- determining a category of the shutter gesture and selecting an exposure time based on the category of the shutter gesture;
- and
- capturing the target image at the exposure time with the first image sensor in response to determining the sequence of images captured with the second image sensor includes the shutter gesture from the user.
An imaging system comprising:
- a first image sensor;
- a second image sensor;
- and
- control circuitry coupled to transmit a shutter signal to the first image sensor and coupled to receive image data from the second image sensor, wherein the control circuitry includes a non-transitory machine-accessible storage medium that provides instructions that, when executed by the imaging system, will cause the imaging system to perform operations comprising:
- activating the first image sensor;
- capturing a sequence of images with the second image sensor, wherein each image in the sequence of images is captured with only a portion of pixels in sectors of the second image sensor;
- determining if the sequence of images captured with the second image sensor includes an image capture pattern from a user;
- determining a category of the image capture pattern, wherein the shutter signal controls an exposure time of the first image sensor based on the category of the image capture pattern;
- sending the shutter signal from the control circuitry to the first image sensor when the image capture pattern is included in the sequence of images captured with the second image sensor;
- and
- capturing a target image at the exposure time with the first image sensor in response to receiving the shutter signal from the control circuitry.
A non-transitory machine-accessible storage medium that provides instructions that, when executed by an image capturing device, will cause the image capturing device to perform operations that initiate an image capture of a target image without physical contact with the image capturing device to initiate the image capture, the operations comprising:
- activating a first image sensor for capturing a target image;
- capturing a sequence of images with a second image sensor, wherein the first image sensor and the second image sensor are included in the image capturing device, wherein each image in the sequence of images is captured with only a portion of pixels in sectors of the second image sensor;
- determining if the sequence of images captured with the second image sensor includes a shutter gesture from a user;
- determining a category of the shutter gesture and selecting an exposure time based on the category of the shutter gesture;
- and
- capturing the target image at the exposure time with the first image sensor in response to determining the sequence of images captured with the second image sensor includes the shutter gesture from the user.
