Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The preposition cameras with fixed focus vertical view of one that Fig. 1 provides for the utility model embodiment;
Fig. 2 is a kind of lens group that the utility model embodiment provides preposition cameras with fixed focus end view static relative to sensitive chip;
A kind of lens group that Fig. 3 provides for the utility model embodiment is being parallel to the preposition cameras with fixed focus end view of sensitive chip direction movement;
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1,2, Fig. 1 preposition cameras with fixed focus of one provided for the utility model embodiment are provided.The preposition cameras with fixed focus end view of one that Fig. 2 provides for the utility model embodiment.
In a kind of concrete execution mode, the utility model provides a kind of preposition cameras with fixed focus, comprises lens group 104 and sensitive chip 106, also comprises: the gyroscope 101 gathering wobble information; According to the microprocessor of described wobble information calculation compensation displacement; The control and drive system 102 of described lens group movement is driven according to described compensate for displacement amount; Positional information after described lens group being moved feeds back to the Hall element of described control and drive system.
Camera under static state, lens group 104 mediates, image formation by rays is in the center of sensitive chip 106, when there is skew in light, can not image in the center of sensitive chip 106, cause the image frame of shooting fuzzy, the preposition cameras with fixed focus that the utility model provides is after sensing that self rocks, can drive lens group 104 that respective direction occurs to move, make incident light after lens group 104, be in the center of sensitive chip 106 all the time.Specifically, the wobble information collected is changed into the signal of telecommunication and gives microprocessor by gyroscope 101, and microprocessor is according to wobble information calculation compensation displacement.Wherein, compensate for displacement amount is exactly the displacement needing movement according to the lens group 104 that wobble information is calculated, according to compensate for displacement amount, control and drive system 102 controls to drive lens group 104 to move, it is to be noted, owing to being preposition cameras with fixed focus, lens group 104 can only move in the direction being parallel to sensitive chip 106, and the direction namely perpendicular to motor 103 inwall is moved.The motion that control and drive system 102 has promoted lens group 104 carrys out the impact that compensate for jitter produces, and Hall element feeds back to control and drive system 102 the positional information of lens group 104, thus forms closed-loop control.
Owing to adding gyroscope 101, microprocessor, control and drive system 102 and Hall element in existing preposition cameras with fixed focus, by gather wobble information and analyze wobble information obtain lens group 101 should the displacement of movement, make light by offseting after lens group 104, still image is focused on sensitive chip 106, form image clearly, then the positional information after lens group 104 being moved feeds back to Hall element, is convenient to calculate the displacement of lens group 104 next time.
Further, in order to make image stabilization when taking pictures, prevent the shake of hand on the impact of quality of taking pictures.When pressing shutter, the shake action of record hand, the shake of hand is fed back to microprocessor, more steady and audible picture can be caught, wherein, the instrument of record dither action is gyroscope 101, and described gyroscope 101 is the gyroscope gathering displacement information, and displacement information is the minor shifts amount that camera produces due to shake.In like manner, described gyroscope 101 is the gyroscope of acquisition angle velocity information.Gyroscope 101 both can gather displacement information also can acquisition angle velocity information, by recording and the displacement information stored because shake produces or angular velocity information.
Further, the direction that can only be parallel to sensitive chip 106 due to lens group 104 is moved, and the direction namely perpendicular to motor 103 inwall is moved.So, when lens group 104 moves, the moving direction that lens group 104 is fixing can be set, realize lens group 101 displacement by control and drive system 102.Described control and drive system 102 is drive lens group 104 to be parallel to described sensitive chip 106 and along the control and drive system 102 of Y-direction movement according to described compensate for displacement amount driving lens group 101 being parallel to the control and drive system 102 of described sensitive chip 106 and movement in X direction or described control and drive system 102 according to described compensate for displacement amount.It is to be noted, X-direction and Y-direction are all in the plane being parallel to sensitive chip 106, X-direction and Y-direction are preferably mutually vertical, also can have a certain degree, object better allows the light of subject enter into lens group, in sensitive chip 106 centre focus, form image clearly.
The utility model provides a preposition cameras with fixed focus, the situation of the fuzzy pictures produced because of shake in shooting process can be prevented, and, even if under dark situation, the shake of picture also can be alleviated, prolonging exposure time, thus improve the shooting quality of electronic equipment under dark situation, the imaging definition taken the photograph before can effectively strengthening, complies with electronic product development trend, makes product more possess the market competitiveness.
The utility model additionally provides a kind of electronic equipment, comprises above-mentioned preposition cameras with fixed focus, and described preposition cameras with fixed focus is connected with the screen of described electronic equipment.Electronic equipment can be mobile phone, IPAD or camera etc., and preposition cameras with fixed focus can be connected with the screen of electronic equipment, is arranged at in the same plane of electronic equipment visible range, is convenient to gather image.
Finally, it should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ...
