Body illustrates that the part and the positioned opposite of step, numerical expression and numerical value for otherwise illustrating in these embodiments do not limit this
The scope of invention.
The description only actually at least one exemplary embodiment is illustrative below, never as to the present invention
And its any limitation applied or use.
May be not discussed in detail for technology, method and apparatus known to person of ordinary skill in the relevant, but suitable
In the case of, the technology, method and apparatus should be considered as a part for specification.
In all examples shown here and discussion, any occurrence should be construed as merely exemplary, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined in individual accompanying drawing, then it need not be further discussed in subsequent accompanying drawing.
The invention provides a kind of camera lens to be assembled and the assemble method of image sensor.Fig. 3 is shown according to the present invention
The camera lens to be assembled of one embodiment and the assemble method of image sensor.Referring to Fig. 3, the method at least includes step S302 extremely
Step S306.
Step S302, camera lens to be assembled and image sensor are assembled, wherein, the surface rendering of camera lens to be assembled has
Resolution chart, resolution chart is only realized being imaged on image sensor after the light beam for receiving specific light source injection；
Step S304, there is provided specific light source, using specific light source on image sensor imaging test figure；
Step S306, according to the imaging of resolution chart, judges whether camera lens to be assembled assembles with image sensor qualified.
The camera lens to be assembled that the present invention is provided and the assemble method of image sensor, paint by the surface of camera lens to be assembled
Resolution chart is formed with, the resolution chart is imaged on image sensor by the irradiation of specific light source, according in image sensor
The resolution chart of imaging, judges whether camera lens to be assembled assembles with image sensor qualified.Relative to prior art, the present invention is carried
The camera lens to be assembled and the assemble method of image sensor for supplying, it is no longer necessary to a test card is set, operating procedure is reduced, separately
Outward, due to no longer needing to set test card again, it is to avoid when being not in being parallel to each other due to test card and image sensor
Assemble the assembly error for causing to camera lens to be assembled.
The specific light source that above-mentioned steps S102 is related to is the light beam with particular range of wavelengths, specifically, for example, ultraviolet
Light, infrared light etc..It should be noted that, when camera lens to be assembled is irradiated with the light source of visible ray, it is arranged on camera lens table to be assembled
The resolution chart in face can not be imaged on image sensor, this ensure that using assembling qualified camera lens and image sensing
When device object to external world is shot, the resolution chart for being arranged on camera lens surface to be assembled will not be enterprising in image sensor
Row imaging.
In the embodiment of the present invention, camera lens to be assembled surface set resolution chart can for it is following any one：Cross
Shape, circle, square, triangle.Preferably, the resolution chart on camera lens surface to be assembled is arranged on around camera lens to be assembled
Central axis be uniformly distributed.
If the resolution chart being arranged on camera lens surface to be assembled is uniformly distributed around the central axis of camera lens to be assembled,
In above-mentioned steps S108, according to the imaging of resolution chart, judge whether camera lens to be assembled assembles with image sensor qualified, specifically
For, if the lines of the imaging of resolution chart are integrally presented clear, and resolution chart imaging around the center of image sensor
Axis is uniformly distributed, it is determined that it is qualified that camera lens to be assembled and image sensor are assembled, i.e., camera lens to be assembled and image sensor phase
Mutually parallel and both central axes；If there are obscure portions in the lines of the imaging of resolution chart, or, resolution chart
It is imaged the central axis not around image sensor to be uniformly distributed, it is determined that camera lens to be assembled does not conform to image sensor assembling
Lattice.
If the imaging lines of resolution chart are integrally presented clear, and resolution chart imaging not around image sensor
Central axis is uniformly distributed, but deviate from the central axis of image sensor, then can determine camera lens to be assembled with image
Shifted when sensor is assembled so that both central axis do not overlap, and then can be to the group of camera lens to be assembled
Dress is adjusted correspondingly.
If there are obscure portions in the imaging lines of resolution chart, and resolution chart imaging in image sensor
Heart axis is uniformly distributed, then can determine that camera lens to be assembled is rotated when being assembled with image sensor so that right
When the resolution chart for being arranged on camera lens surface to be assembled is imaged, the part lines of resolution chart are caused fuzzy feelings occur
Condition, and then the assembling of camera lens to be assembled can be adjusted correspondingly.
Although being described in detail to some specific embodiments of the invention by example, the skill of this area
Art personnel it should be understood that example above is merely to illustrate, rather than in order to limit the scope of the present invention.The skill of this area
Art personnel to above example it should be understood that can modify without departing from the scope and spirit of the present invention.This hair
Bright scope is defined by the following claims.
