Struct PixelArraySize

pub struct PixelArraySize(pub Size);

The camera sensor pixel array readable area vertical and horizontal sizes, in pixels.

The PixelArraySize property defines the size in pixel units of the readable part of full pixel array matrix, including optical black pixels used for calibration, pixels which are not considered valid for capture and active pixels containing valid image data.

The property describes the maximum size of the raw data captured by the camera, which might not correspond to the physical size of the sensor pixel array matrix, as some portions of the physical pixel array matrix are not accessible and cannot be transmitted out.

For example, let’s consider a pixel array matrix assembled as follows

starting with two lines of non-readable pixels (x), followed by N lines of readable data (D) surrounded by two columns of non-readable pixels on each side, and ending with two more lines of non-readable pixels. Only the readable portion is transmitted to the receiving side, defining the sizes of the largest possible buffer of raw data that can be presented to applications.

This defines a rectangle whose top-left corner is placed in position (0, 0) and whose vertical and horizontal sizes are defined by this property. All other rectangles that describe portions of the pixel array, such as the optical black pixels rectangles and active pixel areas, are defined relatively to this rectangle.

All the coordinates are expressed relative to the default sensor readout direction, without any transformation (such as horizontal and vertical flipping) applied. When mapping them to the raw pixel buffer, applications shall take any configured transformation into account.
