Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
The invention provides an assembling method of a lens to be assembled and an image sensor. Fig. 3 illustrates an assembly method of a lens to be assembled and an image sensor according to an embodiment of the invention. Referring to fig. 3, the method includes at least steps S302 to S306.
Step S302, assembling the lens to be assembled and the image sensor, wherein a test pattern is drawn on the surface of the lens to be assembled, and the test pattern realizes imaging on the image sensor only after receiving a light beam emitted by a specific light source;
step S304, providing a specific light source, and imaging a test pattern on the image sensor by using the specific light source;
and S306, judging whether the lens to be assembled is qualified to be assembled with the image sensor according to the imaging of the test pattern.
The invention provides an assembling method of a lens to be assembled and an image sensor, which comprises the steps of drawing a test pattern on the surface of the lens to be assembled, imaging the test pattern on the image sensor through the irradiation of a specific light source, and judging whether the lens to be assembled and the image sensor are assembled to be qualified or not according to the test pattern imaged on the image sensor. Compared with the prior art, the assembling method of the lens to be assembled and the image sensor does not need to arrange a test card any more, reduces the operation steps, and avoids the assembling error caused by assembling the lens to be assembled when the test card and the image sensor are not parallel to each other because the test card does not need to be arranged any more.
The specific light source involved in the above step S102 is a light beam having a specific wavelength range, specifically, for example, ultraviolet light, infrared light, or the like. When the lens to be assembled is irradiated by the light source of visible light, the test pattern arranged on the surface of the lens to be assembled cannot be imaged on the image sensor, so that it is ensured that the test pattern arranged on the surface of the lens to be assembled cannot be imaged on the image sensor when the lens and the image sensor which are assembled in a qualified manner are used for shooting an external object.
In the embodiment of the present invention, the test pattern disposed on the surface of the lens to be assembled may be any one of the following: cross, circular, square, triangular. Preferably, the test patterns provided on the surface of the lens to be assembled are evenly distributed around the central axis of the lens to be assembled.
If the test pattern arranged on the surface of the lens to be assembled is uniformly distributed around the central axis of the lens to be assembled, in the step S108, judging whether the lens to be assembled is assembled with the image sensor to be qualified according to the imaging of the test pattern, specifically, if the line of the imaging of the test pattern is wholly clear and the imaging of the test pattern is uniformly distributed around the central axis of the image sensor, determining that the lens to be assembled and the image sensor are assembled to be qualified, namely, the lens to be assembled and the image sensor are parallel to each other and the central axes of the lens to be assembled and the image sensor are coincident; and if the imaged lines of the test pattern are partially blurred or the images of the test pattern are not uniformly distributed around the central axis of the image sensor, determining that the lens to be assembled and the image sensor are not assembled properly.
If the imaging lines of the test pattern are clear as a whole, and the imaging of the test pattern is not uniformly distributed around the central axis of the image sensor but deviates from the central axis of the image sensor, it can be determined that the lens to be assembled is offset when being assembled with the image sensor, so that the central axes of the lens to be assembled and the image sensor are not overlapped, and the assembly of the lens to be assembled can be correspondingly adjusted.
If the imaging lines of the test pattern are partially blurred and the imaging of the test pattern is uniformly distributed around the central axis of the image sensor, it can be determined that the lens to be assembled rotates when being assembled with the image sensor, so that when the test pattern arranged on the surface of the lens to be assembled is imaged, the situation that the partial lines of the test pattern are blurred can be caused, and further, the assembly of the lens to be assembled can be correspondingly adjusted.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
