Description

Image pickup apparatus

Technical Field

The present invention relates to an image pickup apparatus, and more particularly, to an image pickup apparatus having an adjustable focal position.

Background

The existing camera, no matter single-lens camera or double-lens camera, can't adjust the focal length position of the lens, because the focal length of the lens can't be adjusted, under the motionless condition of the camera, the distance between the object and the lens is also unchanged, and the object has longitudinal depth (namely, the linear distance between different parts of the object and the lens is different), so the unchanged focal length leads to the real stereoscopic effect of the object which is difficult to truly reflect finally through the image imaged by the lens, thereby the finally obtained stereoscopic image and the real object have deviation in the proportional size.

Therefore, there is a need for a camera device with better and more realistic stereoscopic effect.

Disclosure of Invention

The invention aims to provide a camera device with better and more real image stereoscopic effect.

The invention provides a camera device, which comprises a lens, a CCD device, a controller, a power supply unit and a processor, wherein the lens comprises a shell, a lens and a support piece, the shell and the support piece are both in a cylindrical structure, the shell is sleeved outside the support piece, the support piece is arranged in a manner of sliding up and down relative to the shell, a magnet is embedded in the support piece around the periphery of the support piece, the lens is horizontally embedded in the support piece, a coil is also arranged in the support piece, and when alternating current is supplied to the coil, the support piece can slide relative to the shell to change the focus position of the lens; the CCD device is arranged in the shell and is opposite to the lens, the CCD device, the coil and the power supply unit are electrically connected with the controller, the controller adjusts the power supply unit to supply alternating current to the coil by means of images picked up by the CCD device, the processor is in communication connection with the CCD device, receives the images picked up by the CCD device and superposes the images to form a new image

Preferably, the support member of the image pickup apparatus of the present invention has an inwardly projecting snap ring, and the lens is horizontally snapped in the snap ring.

Compared with the prior art, when alternating current is supplied to the coil, the energized coil and the magnetic field of the magnet embedded in the support part around the circle generate interaction force (namely ampere force), the magnet is embedded in the support part, and the support part can slide relative to the shell, so that the support part can slide up and down in the shell under the interaction force generated between the energized coil and the magnet, the displacement and the direction of the support part sliding up and down in the shell can be changed by changing the magnitude and the direction of the alternating current in the coil, the lens embedded in the support part can be driven to synchronously slide up and down by the sliding of the support part, and the focal position of the lens can be changed by the vertical sliding of the lens; according to the characteristic that when the lens is focused on the focal point, the brightness of the pixel on the corresponding CCD device reaches the peak value, therefore, when in use, the controller adjusts the magnitude and direction of the alternating current provided by the power supply unit to the coil in real time through the brightness of the pixel in the image picked up by the CCD device, so that the lens is continuously moved, the focus position of the CCD device is changed continuously, the CCD device picks up the image corresponding to the focus position every time the focus position is changed, finally, the brightness of pixels in the image picked up by the CCD device is at the peak value, the processor stores the pixels in the image picked up by the CCD device when the pixels are at the peak value, forms a new image by superposing the peak values of the stored images and outputs the new image, the new image formed by superposition can truly reflect the front-back distance relation of the object, thereby forming a real stereoscopic image with good stereoscopic effect.
