Abstract
A handheld portable imaging device (100) including a first array of pixels and a second array of pixels embedded within the first array. A processor coupled to the first and second arrays processes data read from first array independently of data read from the second array. In one embodiment, data read from the first array is processed as an image, and data read from the second array is processed relatively quickly for controlling a lens actuator that focuses an image on the first array. In another embodiment, the data from the second array is used to stabilize an image captured by the first array.
Claims17
A handheld portable imaging device comprising:
- a first array of light sensitive pixels;
- a second array of light sensitive pixels embedded within the first array;
- a processor coupled to the first array and to the second array,
- the processor configured to process data read from second array processed independently from data read from the first array.
The imaging device 5, the pixels of the first array have a color filter associated therewith and the pixels of the second array are devoid of a color filter.
A method in a handheld portable imaging device, the method comprising:
- capturing data with a first array of light sensitive pixels;
- capturing data with a second array of light sensitive pixels, the second array of light sensitive pixels embedded within the first array of light sensitive pixels;
- processing data captured by the first array of light sensitive pixels independently of the processing of data captured by the second array of light sensitive pixels.
A handheld portable imaging device comprising:
- a first array of light sensitive pixels;
- a second array of light sensitive pixels embedded within the first array,
- the first array is larger than the second array;
- a processor coupled to the first array and to the second array,
- the processor configured to read data from first array independently of data read from the second array.
