Embodiment Construction

[0038] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] The mask camera structure is as follows figure 1 As shown, 1 is the mask plate, and 2 is the photosensor array. The mask plate is made of a piece of transparent glass coated with a metal film, such as image 3 As shown, the black area is the coating area, the coating area is opaque, and the white area is the light transmission area. The two-dimensional mask pattern is generated by multiplying two one-dimensional near-perfect sequences.

[0040] The pixels of the photoelectric sensor array can receive the object-side light through the light-transmitting area of ​​the mask. If the two-dimensional mask is multiplied by two one-dimensional sequences, the encoding of the object-side light is formed on the photoelectric sensor array:

[0041] Y=φ L Xφ R T (10)

[0042] Among them, Y is the encoded image output by the photoelectric sensor ...

Abstract

The invention discloses a mask plate of a mask plate camera. The two-dimensional mask is the product of two one-dimensional sequences, and each one-dimensional sequence is composed of a nearly perfect sequence; specifically, the mask is generated from two one-dimensional sequences, and according to the required mask length, each Each one-dimensional sequence is composed of one or more complete near-perfect sequences, and the two one-dimensional sequences are multiplied as column vectors and row vectors to obtain the required two-dimensional mask matrix. The invention improves the imaging quality and image signal-to-noise ratio of the mask camera, realizes high-quality imaging of the mask camera, expands the design mode of the encoding imaging coding array, and lays a foundation for the high-quality imaging of the mask camera.

Description

technical field [0001] The invention belongs to the technical field of digital imaging, and relates to the improvement of imaging quality and signal-to-noise ratio of a mask camera, and in particular to a mask of a mask camera. [0002] technical background [0003] Due to the existence of complex lenses in traditional cameras, the entire camera is bulky, which limits the application of the camera. For example, in aerospace remote sensing imaging, the camera is usually required to have a small mass, and in biomedical imaging (medical gastroscope, etc.), the camera is often required to have a small volume, and in these cases, the traditional camera is powerless. Therefore, how to achieve ultra-thin lensless imaging is an important research direction in the field of optical imaging. The mask camera consists of a mask and a photoelectric sensor array, and is a new type of ultra-thin lensless camera. Its thickness is only a few millimeters. Therefore, the mask camera has great...
