Abstract: An image sensor includes: a chip structure including normal pixels and auto focus pixels; a grid structure disposed on the chip structure; and color filter regions defined by the grid structure over the chip structure. The color filter regions include normal filter regions and auto focus filter regions. The normal filter regions correspond to the normal pixels. The chip structure includes a first region at a first distance, and a second region a second distance greater than the first distance. The auto focus filter regions include a first auto focus filter region on the first region and a second auto focus filter region on the second region. A first width of a first grid portion disposed adjacent the first auto focus filter region among the grid structure is narrower than a second width of a second grid portion disposed adjacent the second auto focus filter region among the grid structure.

Abstract: A device and method with battery state estimation are disclosed. A method includes charging a battery in a constant current (CC) charging mode, iteratively updating a full state of charge (SOC) value of the battery while in the CC charging mode, when a measured voltage value of the battery is determined to be greater than or equal to a cutoff voltage value, switching from the CC charging mode to a constant voltage (CV) charging mode and charging the battery in the CV charging mode, and iteratively updating the full SOC value while the battery is in the CV charging mode.
