[0028] The implementation of the present invention will be described in detail below by taking a 3D light field camera as an example.
[0029] Please refer to attached figure 1 , a 3D light field camera, comprising a CCD image sensor 1 and a lenticular lens array 2 arranged parallel to each other, the lenticular lens array 2 is composed of several lenticular lenses 21 arranged side by side, the CCD image sensor 1 and the lenticular lens The distance between the arrays 2 is equal to the focal length of the lenticular lenses 21 . Wherein, the CCD image sensor 1 is used to record image information, which is covered with CCD pixels; the cylindrical lens array 2 is used to separate and focus the externally incident light on the CCD image sensor and form interpenetrating Arranged multiple parallax maps, because the distance between the CCD image sensor 1 and the lenticular lens array 2 is equal to the focal length of the lenticular lens, the lenticular lens array 2 can make multipl...

[0032] like figure 2 As shown, the difference between this embodiment and the first embodiment is that a light-transmitting substrate 4 is used between the CCD image sensor 1 and the lenticular lens array 2 to replace the gasket 3 in the first embodiment. The thickness of the transparent substrate 4 is equal to the focal length of the lenticular lens 21 . In this way, external light can be imaged on the CCD image sensor after passing through the lenticular lens array to form a plurality of parallax maps interspersed with each other.
[0033] The present invention also provides a method for processing images captured by a 3D light field camera as in Embodiment 1 or Embodiment 2, comprising the following steps:
[0034] S1 sequentially extracts the image information of the CCD pixel column at the same position of each unit and combines them into multiple disparity maps, and numbers the multiple disparity maps according to the order of extraction;
