The invention will now be further explained with the help of the following schematic drawing, in which: - fig. 1 shows a schematic side view of an apparatus according to the present invention, 30 - fig. 2 shows a schematic side view of an alternative embodi ment of an apparatus according to the present invention, - fig. 3 shows a schematic perspective view of the camera comprising a calibration knob, and - fig 4 shows a side view of an alternative embodiment of an 35 apparatus according to the present invention.
In the drawing, same parts are indicated with same reference numerals. However, not all parts that are required for a correct functioning of the apparatus are shown in the drawing, for reason of simplicity.
5
Fig. 1 shows a schematic embodiment of an apparatus 1 according to the present invention. The apparatus 1 comprises a frame 2 and a sub-frame 3. The frame 2 and sub-frame 3 are hingedly connected by means of an articulated joint 4. The frame 2 is by means of a suction 5 cup 5 connected to a windshield 6 of a vehicle. The sub-frame 3 comprises provisions 7, 8 for holding an electronic device 9.
A camera 10 is provided in the joint 4. Since the joint 4 is firmly connected to the frame 2, the camera 10 will nearly not suffer from any additional vibrations or movements, other than movements of 10 the vehicle itself.
An alternative embodiment is shown in Fig. 2, wherein the apparatus 1' comprises a differently embodied sub-frame 3'. The sub-frame 3' comprises an arm 11 and a mounting cradle 12 for an electronic device 9. The arm 11 is connected to the frame 2, whereas the cradle 12 15 is hingedly connected to said arm 11 by means of joint 13.
The joint 13 may be embodied as a ball joint, which provides for a 3-dimensional rotational movement of the cradle 12 with respect to the arm 11.
The apparatus 1' as shown in Fig. 2 comprises a camera 10' 20 which is connected to the sub-frame 3', more in particular to the arm 11 of the sub-frame 3'. The camera 10' may be connected to the sub-frame 3' by means of a ball joint, such that a calibration of the camera can be easily performed. A calibration of the camera 10, 10' is generally required, for directing the camera such that an adequate 25 view is obtained.
For example, if the apparatus 1, 1' is connected to a wind shield 6, the direction of the camera 10, 10' should be adapted to the angle under which said windshield 6 is positioned. Generally, it is required to position the camera 10, 10' such that a forward view 30 is obtained, i.e. in the direction of the front side of the vehicle, and wherein the camera 10, 10' is positioned generally horizontally. The camera may be positioned horizontally both in lateral and longitudinal direction.
A calibration means is schematically shown in Fig. 3. The cam-35 era 10, 10' (not shown) is placed with at least one rotational freedom in a frame (not shown) and connected to a calibration knob 14. The calibration knob 14 comprises an indicator 19 indicating the view direction of the camera 10, 10'.
6
If the camera 10' is connected to the sub-frame 3' as shown in Fig. 2, the connection may be embodied as a ball joint 16. Such ball joint 16 provides for a generally 3-dimensional rotational calibration of the camera 10'.
5 The camera 10, 10' is connected to the electronic device 9 by means of a wired connection 17. Such wired connection 17 may consist of a data transport cable as well as a power connector for withdrawing electricity from the electronic device or from a vehicle's battery.
10 An alternative embodiment of an apparatus according to the in vention is shown in Fig. 4. The apparatus is embodied as a base stand to be placed on a dashboard of a vehicle, or on a like surface. The base 19 may be connected to the dashboard or be placed thereon. From the base 19, a frame 2 extends upwards and comprises a joint 13 to 15 which a cradle 12 is connected, analogous to the fig. 2. Said frame 2 may be embodied as a leg.
As shown in fig. 4, a navigation device 9 is placed in said cradle 12. The navigation device comprises a memory card 18. Image data, obtained by means of the camera 10 may be stored on said memory 20 card 18. To that end, the camera is suitably connected to said navigation device 9 by means of a wired connection 17. Alternatively, the wired connection 17 may consist of a data transport cable as well as a power connector for withdrawing electricity from the electronic device or from the vehicle's battery.
25 The apparatus 1 according to the invention is placed at the inside of the vehicle. It may be connected to the windshield or it may be placed on the dashboard or another suitable surface inside the vehicle. The camera 10, 10' comprises a lens and a light sensitive chip (for example a CCD or CMOS chip, not shown). The lens is di- 30 rected to the windshield 6 of the vehicle and hence directed to the outside of the vehicle. A memory card 18 for storing image data made with said camera 10, 10' is provided in the apparatus 1 or in the electronic device 9 (as shown in the schematic drawing). The electronic device 9 is connected to the wired connection 17 for receiving 35 image data from the camera 10, 10'. The electronic device 9 may comprise an apparatus for viewing said image data or for storing the data. The camera's operating commands can be integrated in an interface of the electronic device 9. The interface could be based on a touch screen or on speech-recognition as is generally known for cell 7 phones and navigation devices. A plurality of cameras 10, 10' taking images of the outside of the vehicle in different directions and all provided with transmission means, designed to cooperate with receiving means in the electronic device or another receiving station, can 5 be embodied such that recorded image data are transmitted (wired or wireless) to the electronic device or another receiving station for storing and optionally processing said image data.
The images can be transferred by a wired connection 17 through the sub-frame 3, 3' and optionally the cradle 12 to the electronic 10 device 9. The electronic device 9 may be connected to the connection 17 in the cradle 12 or provision 7, through a USB or the like socket and plug connection.
The recorded images can be sequentially written to the memory-card. The oldest images recorded will be overwritten by new images 15 using the FIFO algorithm (First-in First-out).
When the user connects the Navigation unit to a receiving station, like a personal computer, a television or the like, a software program copies the recorded images to said receiving station. A generally accepted format for storing said image data, like MPEG, H264 20 or HD, is preferred.
As the apparatus 1 is detachable from the electronic device 9, it can be replaced by a replacement model. For example, a camera with a different light sensitive chip, for example with night-vision or higher definition than the original chip, might be used as a replace-25 ment. This provides the advantage that an electronic device can be upgraded with an improved camera, without having to replace the electronic device itself.
As a matter of fact, all cameras available on the market can be used in the present invention, as far as the camera can be incorpo-30 rated inside the apparatus 1. The size and weight of the camera should preferably be as small and low, respectively, as possible.
Since the windshield 6 of a vehicle is not completely flat, and windshields of cars and trucks in general are embodied differently, the camera is provided with a calibration knob 14 allowing a user to 35 adjust a positioning of the camera for a proper view of the road ahead. Most cars have a windshield angle between 30 and 40 degrees. In trucks and buses the windshield can be almost entirely vertical (90 degrees). A vertical variation range of preferably at least 60 degrees therefore will be sufficient.
8
Apart from adjusting the vertical angle of the camera, the calibration knob 14 may be embodied such as to enable an adjustment in the horizontal direction of the camera, as well. This enables an attachment to a left corner of the windshield or a right corner of 5 the windshield. Generally, a horizontal variation range of maximally about 30 degrees will be sufficient.
Rotating (R) the knob 14, as shown in Fig. 3, will provide in a variation of the vertical angle of the camera 10. A sliding movement (F) of the knob 14 in the slit 15 will provide for a variation of the 10 horizontal viewing angle of the camera 10. As shown in Fig. 3, the camera 10 is in an almost vertical position, directing upwards in the plane of drawing of fig. 3.
As a matter of fact, an adjustment of the viewing angles of the camera may be obtained by means of a calibration knob that is pro-15 vided inside the housing and that can be reached at by means of a screw driver or the like. Then, a smooth appearance of the apparatus 1 is obtained.
Furthermore, a calibration means may be provided for a variation of the camera's horizon angle, by adjusting the calibration 20 knob 14 in a vertical direction. Then, positioning the apparatus 1 exactly horizontally to the windshield 6 is of minor importance. By adjusting the horizon angle of the camera 10 pictures taken by the camera 10 will be level at all times. In such a case, the slit 15 may be provided as a circular hole for enabling such movement of the knob 25 14.
The camera of the present invention provides the possibility of collecting images of the roads in a central server. For example, the camera or the navigation device may be provided with a wireless or wired connection with a telephone, preferably one with a UMTS or 30 other high speed wireless connection, for example LTE (long term evolution) or LTE2. Every fixed or dynamically calculated time period, an image can be sent to the central server. Especially in case of traffic congestion, images of vehicles in front of the said congestion may provide images so as to enable traffic controllers to deter-35 mine the reason of said congestion. In case of an accident, police and paramedics may be ordered to go to the specific location. Providing a gps-system in the camera or using the navigation device's gps-system, will help further in determining the exact location of the vehicle and hence of the accident.
9
The central server may be provided with control means to instruct the camera or navigation device to amend the send frequency. Such is useful in case of normal traffic circumstances where a low frequency is sufficient. In case of congestion or an accident, a 5 higher frequency may be useful.
In case of car theft or the like search for a specific car, the cameras may be used to identify the identity of cars in the vicinity of said vehicle containing the camera. Image processing may be performed centrally.
10 The apparatus, comprising wireless communication functionality, may include first and second antennas, a receiver, a driver circuit, an image sensor, a correlated double sampling (CDS) unit, a gain control unit, a transmitter and a power source. Of course, the apparatus may also include various other or different components as will be 15 known to those skilled in the art. The apparatus may be in communication with a video receiver unit that is configured to transmit signals recorded by the wireless camera over a communications network, and to receive a series of video signals for display on a screen. As a matter of fact, the electronic device may be embodied such so as to 20 comprise these functional components.
The images taken from the image sensor, which may consist of still or video images, is a so-called raw analog output from the image sensor which is fed into a CDS unit, as is generally applied for converting analog to digital images. The CDS unit takes a first 25 sample and a second sample of the raw analog output. The CDS unit then generates a filtered output that corresponds to the difference between said first and second samples. The purpose of this step is to remove low frequency noise and any offsets common to both samples.
The filtered output of the CDS unit is then fed into a so-30 called gain control unit, which controls the gain of the filtered output in order to prevent later stages from being overloaded. Gain-controlled output of the gain control unit is fed into a transmitter for modulation. The modulated image signals are then transmitted to a receiver unit.
35 A person skilled in the art will recognize that the above func tional components may be implemented in a variety of ways. For example, the image sensor may take the form of a charge-coupled device (CCD), CMOS sensor, or the like. The transmitter, receiver, and antennas may operate according to a variety of protocols, including the 10 IEEE 802.11 RF wireless standards (i.e., 802.11, 802.11a, b, g or n), Bluetooth, HiperLan, and HiperLan/2. The CDS may take the form of two parallel sample-and-hold circuits. The gain control unit may be either an automatic or manual gain control circuit, both of which are 5 well known in the art. And the power source may take the form of a battery, examples of which are well known in the art.
Finally, the camera according to the invention may be used as a surveillance camera. It may have a direct connection with a memory card for storing the images.
