摘要

An embodiment includes capturing, via a first camera, a first image having a first pixel density, a pixel of the first image corresponding to the first optical axis is substantially centered within the first image; capturing, via the second camera, a second image having a second pixel density that is greater than the first pixel density, where a pixel of the second image that corresponds to the first optical axis is off-center within the second image; processing the second image to generate a fourth image such that a pixel of the fourth image that corresponds to the first optical axis is substantially centered within the fourth image, where a pixel density of the first image is substantially equal to a pixel density of the fourth image, and where the fourth image represents a field of view that is substantially equal to field of view represented by the first image.

說明書

At block 706, the method 700 includes processing the first image to generate a third image. Referring to FIGS. 11 and 12 for example, the imaging device 6 can “upscale” the image 80 to generate the image 88 using any image upscaling technique known in the art (e.g., a bilinear upscaling algorithm). That is, the image 88 has a pixel per row density and a pixel per column density that is greater than the respective pixel per row density and pixel per column density of the image 80. The image 88 shows the same field of view as the image 80. The image 88 has a pixel per row density and a pixel per column density that is less than the respective pixel per row density and pixel per column density of the image 84, however.

At block 708, the method 700 includes processing the second image to generate a fourth image such that a pixel of the fourth image that corresponds to the first optical axis is substantially centered within the fourth image. In this context, a pixel density of the third image is substantially equal to a pixel density of the fourth image and the fourth image represents a field of view that is substantially equal to a field of view represented by the third image.
