Abstract

Methods and systems for a tiled output mode for image sensors are disclosed and may comprise receiving tiled image data from an image sensor that generates output in a tiled format, and sequentially processing the received tiled image data. The received tiled image data may comprise a plurality of lines. A tile received from the image sensor may overlap at least one neighboring tile. The neighboring tiles may be above, below, to the left and/or to the right of the current tile. The size of the received tiled image data may vary dynamically, and may vary based on, for example, a compression format and/or a desired resolution of the image sensor. The method may also comprise generating the tiled image data from an image sensor, and sequentially processing the generated tiled image data.

Claims
