Abstract: An image sensor may include an image pixel array with both image pixels to gather image data and phase detection pixels to gather phase information. The image sensor may dynamically group the phase detection pixels into focus zones. Based on the characteristics of the scene being imaged and the use settings of the image sensor, the image sensor may determine the size, shape, and number of focus zones to be grouped. One or more focus zones may then be used to gather phase information data. The focus zones may vary in size and shape across the pixel array. A scene with low illumination level may result in larger focus zones with more phase detection pixels to ensure reliable phase information data.

Abstract: The technology disclosed here maximizes the size of the display area associated with the mobile device by various camera placement. In one embodiment, the camera is placed inside the mobile device, and can pop outside the mobile device when the camera is activated. When the camera is inactive the camera retracts inside the mobile device, and becomes unnoticeable to the user. In another embodiment, the camera is integrated into the mobile device display as a camera icon. The integrated camera serves two purposes: to record pictures, and to act as a camera icon, that when selected activates the camera. By removing the camera from the front side of the mobile device, or by integrating the camera into the display screen of the mobile device, the size of the mobile device display screen can be increased.
