 What Is an Orientation Sensor and How Is Is Used in a Camera?

When talking about modern cameras an ‘orientation sensor’ is a sensor within a camera which can detect when a photographer switches the camera from a landscape to a portrait orientation. An orientation sensor us usually a type of basic accelerometer which can only detect major changes in orientation. They allow camera display information to be rotated to remain readable by the shooter regardless of whether they are holding the camera vertically of horizontally. Orientation sensors are also used during image playback to allow the user to switch orientation when viewing portrait images.
