In a specific embodiment, the present embodiment provides an image pickup apparatus, which may be specifically a monitoring image pickup apparatus, and specifically the image pickup apparatus includes a first lens 1, a second lens 2, a photo sensor chip 3, and a switching device.
The first lens 1 and the second lens 2 are arranged in a reverse manner, so that the opposite two sides can be viewed. In order to make the imaging device completely have no dead angle, the first lens 1 and the second lens 2 are preferably both fish-eye lenses. It should be noted that, the first lens 1 and the second lens 2 are disposed opposite to each other, and may be overlapped in the direction away from each other or may not be overlapped. The lens collects and emits the emitted light through the convex lens of the lens, and the purpose of framing is achieved.
The light sensing chip 3 has a light receiving surface, which receives the light emitted from the lens and can convert the optical signal into an electrical signal. The photosensitive chip 3 may be a CCD device (charge coupled device), a CMOS device (metal oxide semiconductor device), or a CPD device (charge driven device). Specifically, the selection may be performed as needed.
The switching device is used for controlling the light receiving surface of the light sensing chip 3 to alternately receive the light emitted by the first lens 1 and the light emitted by the second lens 2, so that the light receiving surface of the light sensing chip 3 alternately views the images from the first lens 1 and the second lens 2, and the images of the same part of the light receiving surface are prevented from being viewed by the first lens 1 and the second lens 2 at the same time. To view from the second lens 2 after viewing from the first lens 1, and then view from the first lens 1. In order to ensure that the frame rate of the video is good, the switching speed is fast to ensure the continuity. In order to ensure the image pickup effect, uniform switching is preferably performed, so that the time length of the interval between two adjacent viewfinders of the photosensitive chip 3 is the same. The switching device may receive the light emitted from the lens with the light-receiving surfaces thereof alternated by the light-blocking sheet 4. The light receiving chip 3 may be driven to operate so that the light receiving surface of the light receiving chip 3 alternately enters the light path of the first lens 1 and the light path of the second lens 2.
In the embodiment, when the image pickup device is used for recording videos, the first lens 1 and the second lens 2 can be used for viewing from two opposite directions, so that the viewing range of the image pickup device is wide. And the switching device enables the light receiving surfaces of the light sensing chip 3 to receive the emergent light from the first lens 1 and the second lens 2 in a crossed manner, so that the recording of scenes on two sides can be realized. In summary, in the imaging apparatus, two lenses are disposed opposite to each other, so that the viewing surface is increased. Moreover, the photosensitive chip 3 can simultaneously complete the video recording of the first lens 1 and the video recording of the second lens 2 through the switching device, so that the scene video recording at two sides can be simultaneously completed, the video recording range is wide, and the cost is low. In summary, the image capturing apparatus effectively solves the problem of the limited image capturing range of the image capturing apparatus in the prior art.
Further, for convenience of switching, the switching device preferably includes a light shielding sheet 4 capable of blocking light emitted by the lens when the switching device moves to the blocking position, and the photosensitive chip 3 may not rotate at this time, so that the switching device is convenient and simple to operate, and the switching device is correspondingly configured to drive the light shielding sheet 4 to alternately enter and exit the current blocking position, so as to alternately frame a certain lens, and to frame the current lens from other lenses when the current lens does not frame the current lens. Two light-shielding sheets 4 may be provided to shield the light emitted from the first lens 1 and the light emitted from the second lens 2, respectively. Here, only one light-shielding sheet 4 may be provided in order to reduce the overall volume. Specifically, when the light shielding sheet 4 is located at the first blocking position, the light shielding sheet can block the light emitted from the first lens 1 from entering the light receiving surface, wherein the first blocking position should be located on the path of the light emitted from the first lens 1, specifically, the light shielding sheet can block the light emitted from the first lens 1 from passing through the light receiving surface; the light shielding sheet 4 is located at a second blocking position, which is located on the path of the outgoing light of the second lens 2, and can block the outgoing light of the second lens 2 from entering the light receiving surface, specifically, can block the outgoing light of the second lens 2 from passing through the light receiving surface. The switching device further comprises a driving device capable of driving the light shielding sheet 4 to move back and forth between the first blocking position and the second blocking position, so that the light emitted from the first lens 1 and the light emitted from the second lens 2 alternately enter the light receiving surface of the photosensitive chip 3. The driving source of the driving device mainly adopts a motor and is correspondingly provided with a transmission mechanism, and the transmission mechanism is generally a lead screw nut transmission mechanism or a crank slider mechanism.
Considering that the light receiving surface of the light receiving chip 3 is a plane, in order to allow both the light emitted from the first lens 1 and the light emitted from the second lens 2 to enter the light receiving surface, a reflective mirror 5 may be provided, and the light emitted from the first lens 1 and/or the light emitted from the second lens 2 may be projected onto the light receiving surface by the reflective mirror 5. In order to reduce the cost, it is preferable that the emitting end of the first lens 1 is disposed opposite to the light receiving surface of the light sensing chip 3, so that the light emitted from the first lens 1 can be directly projected onto the light receiving surface of the light sensing chip 3. The second lens 2 is offset from the first lens 1, and a reflective mirror 5 is disposed to reflect the light emitted from the emitting end of the second lens 2 onto the light receiving surface of the photosensitive chip 3.
As described above, the photosensitive chip 3 may be driven to rotate, so that the photosensitive chip 3 may alternately receive the light emitted from the first lens 1 and the light emitted from the second lens 2. Specifically, when the light sensing chip 3 is rotated to the first angular position, the light receiving surface can receive the light emitted from the first lens 1, and at this time, the light emitted from the second lens 2 cannot be received, so as to avoid overlapping; when the light sensing chip 3 rotates to the second angular position, the light receiving surface can receive the light emitted from the second lens 2, and at this time, the light emitted from the first lens 1 cannot be received, so as to avoid the overlapping. The switching device further comprises a rotation driving device for driving the photosensitive chip 3 to rotate back and forth between the first angular position and the second angular position. Specifically, the light emitted from the first lens 1 and the light emitted from the second lens 2 can be emitted at an angle of 90 degrees to the photosensitive chip 3 through the reflective mirror 5, and at this time, the photosensitive chip 3 rotates at an angle of 90 degrees to a second angle position from a first angle position.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
