Dual sensor camera

摘要

A dual sensor camera that uses two aligned sensors each having a separate lens of different focal length but the same f-number. The wider FOV image from one sensor is combined with the narrower FOV image from the other sensor to form a combined image. Up-sampling of the wide FOV image and down-sampling of the narrow FOV image is performed. The longer focal length lens may have certain aberrations introduced so that Extended Depth of Field (EDoF) processing can be used to give the narrow FOV image approximately the same depth of field as the wide FOV image so that a noticeable difference in depth of field is not see in the combined image.

主权项

1. A camera, comprising:
a first sensor that captures a first image; a first lens that directs light to the first sensor, the first lens having a first focal length; a second sensor that captures a second image; and a second lens that directs light to the second sensor, the second lens having a second focal length that is longer than the first focal length; and wherein the combination of the first sensor and the first lens are substantially aligned with the combination of the second sensor and the second lens to allow each to be directed toward the same subject; the first and second images are combined together to form a single combined image with the second image forming a central portion of the single combined image and a peripheral portion of the first image forming a peripheral portion of the single combined image; the combining of the first and the second images includes at least one of up-sampling the first image and down-sampling the second image; and when the first image is up-sampled, the first image is sharpened after the up-sampling.
