Abstract
The invention discloses a module of array optical cameras free of focus. The module includes a cover of lens, a lens group and graphics chips, wherein the lens group comprises a plurality of lenses. Each lens is equipped with a plurality of secondary lenses, the secondary lenses on the same optical surface are distributed in array, and the positions of the secondary lenses on the optical surfaces which are adjacent to are corresponding. The theoretical pixel value of the lens is the sum of the pixel value of the secondary lenses and can reach 12 million and after being processed by softwares, the module pixel value of the lens can reach 8 million. In practical application, the lens group is matched with the pixel matrix of the graphics chips so that the colors of the images are better and smoother than those of the ordinary high pixel modules, the color variation is lowered, and the lens group can be applied to high pixel modules and can replace some high pixel camera modules made of aspheric surface and composed single lens. The height of the module is effectively lowered to only 3.2mm; therefore, the module meets the requirements of lightness and thinness for electronic products.
Description
Technical field
The invention belongs to the optical camera field, be specifically related to the high pixel of a kind of ultrathin array and exempt from the optical camera of focusing.
Background technology
Progressively to new material, high pixel, microminiaturized development, this just orders about traditional design needs further to improve in the development of camera module.
Conventional lenses needed to connect by packing ring between a plurality of eyeglasses in when assembling, and eyeglass for packing ring assembling need to separately to establish a segment structure regional, so just strengthened lens dimension, and then strengthen the module size, not only expend starting material, and be unfavorable for that product is to lightening development.
After having recorded and narrated machinery in patent documentation 1 (the open 201654308U patent gazette of China), Jiao foreshortens in 100 microns; save spacer ring camera lens directly is glued on the cover glass of image chip with glue, reduce with this method that manufacturing tolerance is made the high-quality optical camera module of exempting to focus.but in patent documentation 1, last surface of exempting from the focusing lens group is optical aspherical surface, can not be directly and the cover glass of image chip directly bonding, be used as the position bonding with the image chip cover glass and need to separately establish a segment structure zone beyond the optics effective diameter, so just increased the bore of exempting from focusing lens, make a slice glass wafer (diameter 200mm) upper obtain exempt from focusing lens product decreased number, thereby lifting exempt from the cost of products of focusing lens, and for the whole optical camera module of exempting to focus, exempt from focusing lens and image chip when bonding, only have the neighboring area bonding, and the centre is still separation, it is not very abundant causing bonded areas, product reliability can not optimization.
Summary of the invention
In order to overcome defects, the invention provides a kind of array optical camera module of exempting to focus, this array optical camera module of exempting to focus can effectively reduce the product height, takes into account simultaneously graphical quality.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of array optical camera module of exempting to focus, comprise camera lens outer cover, lens group and image chip, described lens group is made of some eyeglass stacks, the optical surface of every eyeglass has some story boards, and be positioned at some story boards on same optical surface and be array and arrange, the position of the story board on adjacent optical surface is corresponding.The theoretical pixel value of lens group is story board pixel value sum, can reach 1,200 ten thousand, after processing by software, camera module pixel value can reach 8,000,000, lens group coordinates the picture element matrix of image chip in actual applications, the shooting picture color is finer and smoother than common high pixel module, can effectively reduce aberration, satisfy the more and more higher image quality requirement of product.Lens group of the present invention is used for high pixel module, can substitute the high pixel optics camera module of single the camera lens making that is consisted of by many aspheric surfaces, effectively reduce the module height: the height of single 8,000,000 high pixel camera lenses is usually at 5mm usually, and lens group of the present invention is combined by low pixel story board, height can accomplish to be only 3.2mm, satisfies light, the thin requirement of present consumption electronic product.
Further technical scheme of the present invention is:
At least one optical surface of lens group is the differentiation structural design, and the face type that described differentiation structural design refers to be positioned at least one story board on same optical surface is different from the face type of all the other story boards.The differentiation structural design is in order to coordinate the partition characteristics of each picture element matrix of image chip R, G, B pixel, and chromatism of position that can the balance different color light is consistent the imaging surface of R, G, B different color light, all is imaged on well on the image chip image planes.
The story board that is positioned at same optical surface is one-body molded.Be positioned at some story board integral production cuttings of same optical surface, have higher consistance and bearing accuracy.
Be provided with adhesive coating between adjacent mirror, the bonding eyeglass that is positioned at its both sides of described adhesive coating.Adhesive coating can be high light transmission rate UV glue, and all eyeglasses directly adhesive coating of the high light transmission rate by several micron thickness fit together, and is guaranteeing to reduce the module height under high pixel prerequisite.The lens group periphery stretches out, and strengthens the cementing area that closes of UV, the improving product reliability.
Last surface of described lens group is that tabular and whole face are glued on described image chip.
Described image chip has cover glass, and last surface bonding of described lens group is on described cover glass front surface.Directly closely glued together by high light transmission rate UV glue between last surface of lens group and the cover glass (cover glass) of image chip; the thickness of UV glue is several microns; the spacer ring or the base that save Jiao after keeping between conventional lenses and chip; rear burnt tolerance is down to minimum; reach the effect of exempting to focus, guarantee that the camera module has high picture quality.
the invention has the beneficial effects as follows: the array of the present invention optical camera module group lens group of exempting to focus has some array story boards, the theoretical pixel value of lens group is story board pixel value sum, can reach 1,200 ten thousand, after processing by software, camera module pixel value can reach 8,000,000, lens group coordinates the picture element matrix of image chip in actual applications, the shooting picture color is finer and smoother than common high pixel module, can effectively reduce aberration, satisfy the more and more higher image quality requirement of product, lens group of the present invention is used for high pixel module, can substitute the high pixel optics camera module of single the camera lens making that is consisted of by many aspheric surfaces, effectively reduce the module height, the module height can accomplish only to be 3.2mm, satisfy present consumption electronic product light, thin requirement.
