Image data conversion

Abstract:

Embodiments of the present disclosure relate to an apparatus for converting image data from a Bayer format image to a four-plane image format using two memory channels. An example apparatus includes an interface for receiving the Bayer image including repeating pixel groups, where each pixel group includes a first pixel type, a second pixel type, a third pixel type, and a fourth pixel type. The apparatus also includes a memory and a circuit to write the Bayer image to the memory as four-plane data. The four-plane data includes pixels of the first type and the third type in the Bayer image that are written via the first memory channel, and pixels of the second type and the fourth type in the Bayer image that are written via the second memory channel. Embodiments also relate to converting three sensor image data to a Bayer format image using the two memory channels.
