  • Image sensing apparatus, image sensing method, distance measuring apparatus, and distance measuring method
    Patent number: 10484585
    Abstract: There is provided an image sensing apparatus according to the present invention including: an image recovery portion which recovers an image from a sensed image by using a digital signal processing technique which uses a sparse representation for each measurement matrix; and a distance measurement portion which measures a distance of an object by using a norm of a value using at least light amount information of the estimated pixel which is estimated for each measurement matrix, in which the image recovery portion recovers the image by using the measurement matrix corresponding to the distance measured by the distance measurement portion. According to the present invention, when an image is sensed using compound eyes, image sensing can be performed without a separate distance measuring device or the like.
