Abstract
Image sensors may include an array of image sensor pixels. A subset of the array, sometimes referred to as a region of interest (“ROI”), can be read out using vertical readout lines and diagonal readout lines. The diagonal readout lines enable multiple adjacent or nonadjacent rows in the ROI to be simultaneously read out. Configured and operated in this way, frame rate gains can be achieved by reducing the ROI size in both the Y direction and the X direction.
Claims20
An image sensor comprising:
- an array of image sensor pixels;
- data converters that receive signals from the array of image sensor pixels;
- a plurality of vertical readout lines coupling the array of image sensor pixels to the data converters;
- and
- a plurality of diagonal readout lines coupling the array of image sensor pixels to the data converters.
2 more elements
A method of operating an image sensor, the method comprising:
- using an array of pixels in the image sensor to capture an image, wherein the array of pixels are arranged in rows and columns;
- simultaneously reading signals out from at least two different rows in the array;
- and
- receiving the signals from the at least two different rows in the array at a plurality of data converters.
