Methods and systems described herein address the issue of how to efficiently capture an image circle within an image sensor associated with a wide field of view camera. In one embodiment, a processor obtains several criteria, such as a plurality of sizes of a plurality of image circles, a minimal portion of the image circle to be recorded by the image sensors, and a minimal portion of the image sensors engaged in recording the image. Based on these criteria, the processor determines a number of image sensors, a number of image sensor sizes, and a number of image sensor shapes. In another embodiment, the processor receives additional criteria, such as the desired aspect ratio and the desired shape associated with the image sensor. Based on these criteria, the processor determines a number of image sensors and a number of image sensor sizes.
