Abstract
A method and portable device for capturing a still image is described. The portable device comprises both an image projector for projecting images and a sensor for capturing images. A first image is captured and a flash image is generated based on the captured first image to adjust lighting of the image subject. The generated flash image is projected onto the image subject using the projector and a second image is captured while the flash image is projected onto the image subject.
Claims15
A method of capturing a still image on a portable device comprising:
- capturing first image data of an image subject using an image sensor of the portable device;
- processing the captured first image data to identify a red-eye condition area of the first image data;
- generating a flash image mask light, or red light, from being projected onto the red-eye condition area;
- projecting the generated flash image onto the image subject using a projector of the portable device;
- and
- capturing second image data of the image subject while the flash image is projected.
3 more elements
A portable device comprising:
- an image sensor for capturing image data of an image subject;
- at least one processor coupled to the image sensor for processing the captured image data and generating a flash image to illuminate the image subject;
- a memory unit coupled to the at least one processor storing instructions for execution by the processor, the instructions when executed by the at least one processor configuring the portable device to generate the flash image, the instructions comprising:
- instructions for processing the captured first image data to identify a red-eye condition area of the first image data;
- and
- instructions for generating the flash image to mask light, or red light, from being projected onto the red-eye condition area;
- and
- an image projector for projecting images or videos for display and the generated flash image for adjusting lighting of the image subject.
