Abstract
Methods, systems, and apparatuses are provided to perform phase-detection autofocus control. By way of example, the methods can receive luminance values measured by a plurality of sensing elements in a sensor array, and the sensing elements can include imaging pixels and phase-detection pixels. The methods can compare luminance values measured by at least one of the phase-detection pixels to luminance values associated with a subset of the imaging pixels including two or more imaging pixels. The comparison can be performed at extended horizontal density or full horizontal density along a first sensor-array row that includes the at least one phase-detection pixel and the two or more imaging pixels. The methods can also perform a phase-detection autofocus operation based on an outcome of the comparison.
