Abstract
The utility model relates to a miniature pick-up head which can shoot chromatic vivid images, which comprises camera lenses and a lens mount. The utility model is characterized in that the camera lenses are aspherical camera lenses, and an imaging sensor is arranged behind the aspherical camera lenses. The camera lenses can accurately reflect images onto the imaging sensor, which enables the utility model to shoot vivid dynamic images, and meanwhile the pick-up head has the advantages of small volume and good expressive force for colors. The utility model is especially suitable for being arranged in mobile phones, palm personal computers and portable equipment.
Description
Technical field
The utility model relates to the camera head field, the specifically a kind of minisize pick-up head that can take colored picture rich in detail, and this camera volume is little, good to the expressive force of color, is highly suitable in mobile phone, palm PC and the portable set to be provided with.
Background technology
Minisize pick-up head, usually use and be arranged at various aspects such as mobile phone, visual telephone, palm PC, small digital cameras, toy, embedded aut.eq., watch-dog, multimedia computer, fingerprint identification device, bar code reader, Medical Devices, consider the big visual field that its volume is little and captured when being provided with, add aspheric surface in the lens combination of pick-up lens, be convenient to reduced volume, and have bigger visual angle.
But because their volume has certain limitation, big visual angle often means sacrifices its color representation power and sharpness, and employed in the market camera, and its resolution generally can not surpass 300,000 pixels, and its resolution is very limited.
Owing to its design feature of minisize pick-up head, determine it aspect mobile imaging, to have advantage in the practical application, rather than wide-angle imaging, and we also are to use as mobile imaging when using, so it is often volume is big for the camera group of sphere, does not reach portable effect, not too practical.
Summary of the invention
Based on this, the purpose of this utility model provides a kind of minisize pick-up head that can take the color picture rich in detail, and this camera volume is little, good to the expressive force of color.
Another purpose of the present utility model provides a kind of minisize pick-up head that can take the color picture rich in detail, and this camera volume is little, good to the expressive force of color, can take high-precision dynamic image, and low in energy consumption, the convenient use.
The utility model is achieved in that
A kind of minisize pick-up head that can take the color picture rich in detail, include lens group, lens mount, it is characterized in that this lens group is the aspheric lens group, and this aspheric lens group is provided with imageing sensor behind, imageing sensor is connected on the circuit board, so that clearly take dynamic image.The aspheric lens group makes this lens group can shorten the focusing distance between the lens, reduces the volume of this minisize pick-up head, and simultaneously, this lens group can be reflected to image on the imageing sensor exactly, makes it to shoot clearly dynamic image.
The described minisize pick-up head that can take colored picture rich in detail also is provided with integrated infrared low pass filter coating on its lens group, so that it can filter out unnecessary light, prevent its interference to taking, and improves shooting effect.
Described imageing sensor is the CMOS electro-optical imaging sensors, can become 24 very color dynamic images;
Described aspheric lens group, form by two high precision non-spherical lenses before and after it, the centre is equipped with and these two concave lens that non-spherical lens adapts, the focusing spacing between the lens that is arranged so that of non-spherical lens can become very little, can shorten the length of lens group thus greatly, make the volume of whole camera can be very little, be arranged at mobile phone, watch-dog, palm PC easily, and in other the portable set.
Above-mentioned aspheric lens group, the surperficial radian of the non-spherical lens of its front is greater than the surperficial radian of the non-spherical lens of back, so that take the image that has than broad visual angle, simultaneously this image is reflected to very exactly on the lens group imageing sensor behind.
Above-mentioned aspheric lens group, the non-spherical lens of its front are provided with integrated infrared low pass filter coating, to have suitable filter effect, guarantee captured dynamic image quality.
The described minisize pick-up head that can take colored picture rich in detail, its pedestal is made of sheet metal and flexible material, and sheet metal constitutes bracing frame, and flexible material is filled bracing frame, and forms the protection to sheet metal and lens group.
The utility model adopts above-mentioned frame mode, the setting of aspheric lens group, make this lens group can shorten the focusing distance between the lens, reduce volume of the present utility model, simultaneously, this lens group can be reflected to image on the imageing sensor exactly, makes it to shoot clearly dynamic image, and low in energy consumption, the convenient use.
Description of drawings
Fig. 1 is a contour structures synoptic diagram of the present utility model,
Fig. 2 is a cut-open view of the present utility model.
Embodiment
Shown in Figure 1, be a kind of embodiment of the present utility model.The utlity model has and be arranged at lens mount 10 inner aspheric lens groups, imageing sensor 20, imageing sensor are connected on the circuit board 40, are convenient to captured image information is sent in the control circuit on the circuit board 40 timely and accurately.
This aspheric lens group, its front and back are by two high precision non-spherical lenses 11,13 form: front lens 11 and rear lens 13 (shown in Figure 2), the concave part of two aspheric surface front lenss 11 and rear lens 13 all inwardly is provided with, the centre is equipped with the concave lens 12 that adapts with front lens 11 and rear lens 13, the preceding concave surface of concave lens 12 is corresponding with the projection radian of front lens 11, and the back concave surface of concave lens 12 is corresponding with the projection radian of rear lens 13, the focusing spacing between the lens that is arranged so that of this non-spherical lens can become very little, can shorten the length of lens group thus greatly, make the volume of whole camera can be very little, be arranged at mobile phone easily, watch-dog, palm PC, and in other the portable set.
Shown in Figure 2, in the aspheric lens group, the surperficial radian of its front lens 11, is reflected to this image on the lens group imageing sensor behind so that take the image that has than broad visual angle simultaneously very exactly greater than the surperficial radian of rear lens 13.
Above-mentioned aspheric lens group, the non-spherical lens of its front are provided with integrated infrared low pass filter coating 14, to have suitable filter effect, guarantee captured dynamic image quality.
The described minisize pick-up head that can take colored picture rich in detail, its pedestal is made of sheet metal and flexible material, and sheet metal constitutes bracing frame, and flexible material is filled bracing frame, and forms the protection to sheet metal and lens group.
This of the utility model formation can be taken the minisize pick-up head of color picture rich in detail, and volume is little, good to the expressive force of color, can take high-precision dynamic image, and low in energy consumption, the convenient use.
