US Patent 11089202 Focus adjustment for image capture device

A control system for an image capture device. The control system includes an image sensor including sensor pixels including at least two sub-pixels respectively. First and second pluralities of the sensor sub-pixels capture first and second pixel data with a first and second exposure respectively. An image processor receives image data derived from a first set of the sensor sub-pixels including sub-pixels of the first and second pluralities of the sensor sub-pixels. On the basis of the image data, the image processor generates output data representing at least part of an output image. A focus controller receives focus data derived from a second set of the sensor sub-pixels including at least two of the first plurality of the sensor sub-pixels. On the basis of the focus data, the focus controller generates a control signal for adjusting a focus of the image capture device. Other examples relate to image sensors.
