Description
- The present invention generally relates to monitors, and more particularly relates to a monitor that has a large visual field.
- Nowadays automobiles are often provided with a monitor secured in the tail thereof to cover the blind spots of their rearview mirrors. Generally, the visual angle of the monitor is designed to be about 60 degrees. Because the monitor is secured in the automobile, this visual angle is usually too limited to allow safe driving of the automobile. For example, when the automobile reversing, a driver can only see objects in a range covering a visual angle of about 30 degrees to left and right in which the automobile is reversing, thus increasing the possibility of an accident. Monitors provided with a visual angle of more than 60 degrees can be used to extend the visual field of the driver, but these monitors require expensive optical components such as components with high refractive index or low dispersive power, thus these monitors tend to be more complicated and more expensive.
- What is needed, therefore, is a simple and inexpensive monitor having a large visual field to overcome above-described problems.
- In a preferred embodiment thereof, a monitor used in an automobile includes an image sensor, a visual field adjustor and a display. The image sensing module is secured on the automobile. The visual field adjustor is installed on an incident light path of the image sensing module. The display is electronically connected with the image sensing module and mounted to the automobile.
- Other advantages and novel features will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- Many aspects of the monitor can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present monitor. Moreover, in the drawings, like reference numerals designate corresponding parts through-out the several views.

FIG. 2 is a schematic view of the monitor receiving an optical image signal with an inclination angle to an optical axis of an image sensing module shown inFIG. 1 ; -
FIG. 3 is a schematic view of the monitor in a use state shown inFIG. 1 ; -
FIG. 4 is a schematic view of a monitor in accordance with a second embodiment of the present invention; and -
FIG. 5 is a schematic view of the monitor shown inFIG. 4 in use. - Referring now to the drawings,
FIG. 1 shows amonitor 100 used in an automobile (not shown) according to a first embodiment of the present invention. Additionally, themonitor 100 can be used in other vehicles and also in fixed installations. Themonitor 100 includes animage sensing module 10, avisual field adjustor 20 and adisplay 30. Theimage sensing module 10 is installed in the automobile for receiving optical image signals. An optical axis of theimage sensing module 10 points to the rear of the automobile. Thevisual field adjustor 20 is installed on an incident light path of theimage sensing module 10 to adjust the visual field of themonitor 100. Thedisplay 30 is electronically connected with theimage sensing module 10 and is mounted to the automobile for processing and displaying image signals received by theimage sensing module 10 to a driver of the automobile. - The
image sensing module 10 includes animage sensor 11 and alens module 12. Theimage sensor 11 is a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor. Theimage sensor 11 is secured on an emitting light path of thelens module 12 and electronically connected with thedisplay 30. Optical image signals received by thelens module 12 and arriving at theimage sensor 11 are transformed into electronic image signals by theimage sensor 11. The electronic image signals are transferred to thedisplay 30 to be displayed. Thelens module 12 is installed in the automobile and has a visual angle of 60 degrees. - Also referring to
FIG. 2 , thevisual field adjustor 20 includes amirror 21 and anaxis 22. Themirror 21 is a thin planar mirror that includes two parallel reflectors (not labeled). Themirror 21 is rotatably installed on an incident light path of thelens module 12, and optical image signals reflected by themirror 21 are received by thelens module 12. One end of theaxis 22 is secured on the midpoint of one side of themirror 21. The other end of theaxis 22 is driven by a motor (not shown) installed in the automobile to rotate, thus themirror 21 is also driven to rotate. Speed of rotating theaxis 22 and themirror 21 is at least 50 revolutions per second. In other words, a cycle of rotation of theaxis 22 and themirror 21 is equal to or less than 0.02 seconds. - According to the laws of reflection, if the
mirror 21 and the optical axis (the line OZ shown asFIG. 2 ) of theimage sensing module 10 form an angle of n degrees, an optical image signal with an inclination angle of 2n degrees to an optical axis of theimage sensing module 10 is reflected to travel along the optical axis and received by theimage sensor 11. Therefore rotating themirror 21 through an angle of n degrees results in an effect equal to rotating theimage sensing module 10 through an angle of 2n degrees. In this way, if themirror 21 is rotated through an angle of n degrees from a place where themirror 21 and the optical axis of theimage sensing module 10 form an angle of 0 degrees, the visual field of themonitor 100 is correspondingly rotated through an angle of 2n degrees. Because thelens module 12 has a visual angle of 60 degrees, it receives optical image signals in a range covering a visual angle of 30 degrees to left or right according to the direction in which the automobile is reversing. If themirror 21 is rotated through an angle of 30 degrees from the place where themirror 21 and the optical axis form an angle of 0 degrees, the visual field of themonitor 100 is correspondingly rotated through an angle of 60 degrees, thus the visual field of themonitor 100 covers a visual angle of 30 to 90 degrees according to the direction in which the automobile is reversing. - Referring to
FIG. 3 , when using of themonitor 100, the motor drives themirror 21 to rotate. When themirror 21 rotates to a first place where themirror 21 and the optical axis of theimage sensing module 10 form an angle of 30 degrees in one side, optical image signals in a range covering a visual angle of 30 to 90 degrees to one side according to the direction in which the automobile is reversing are reflected into the visual field of thelens module 12 by themirror 21. When themirror 21 rotates from the first place to a second place where themirror 21 and the optical axis form an angle of0 degrees, themirror 21 can not shield thelens module 12 because it is very thin, thus thelens module 12 receives optical image signals in a range covering a visual angle of 30 degrees in left or right according to the direction in which the automobile is reversing. When themirror 21 rotates to a third place where themirror 21 and the optical axis form an angle of 30 degrees in another side, optical image signals in a range covering a visual angle of 30 to 90 degrees in another side according to the direction in which the automobile is reversing are reflected into the visual field of thelens module 12 by themirror 21. - The optical image signals coming from above three positions all covering a visual angle of 60 degrees are received by the
lens module 12, and arrive at theimage sensor 11. Theimage sensor 11 transforms the optical image signals into electronic image signals and transfers the electronic image signals to thedisplay 30. Thedisplay 30 transforms the electronic image signals into a panoramic image covering a visual angle of 180 degrees behind the automobile. As the rotation cycle of themirror 21 is not more than 0.02 seconds, i.e. less than the time of visual persistence. Before a panoramic image disappears displayed on thedisplay 30 in the driver's eyes, it is replaced by another panoramic image that comes from the optical image signals received by thelens module 12 after themirror 21 rotates. In this way, changing of the panoramic images caused by rotating themirror 21 can-not be sensed by the driver's eyes. Therefore the driver sees that the panoramic images covering a visual angle of 180 degrees behind the automobile are continuously displayed on thedisplay 30. - Referring
FIG. 4 andFIG. 5 , amonitor 200 according to a second embodiment is provided. All components of themonitor 200 are similar to themonitor 100 except that themirror 21 of themonitor 100 is replaced by aprism 41. Theprism 41 is movably installed in the incident light path of thelens module 12. Theprism 41 is made from transparent materials such as glass and includes a trapeziform bottom (not labeled), afirst side 411, asecond side 412, athird side 413 and afourth side 414. Thefirst side 411 is parallel to thesecond side 412 and the area of thefirst side 411 is larger than the area of thesecond side 412. Thethird side 413 and thefourth side 414 both intersect with thefirst side 411 and thesecond side 412. Thethird side 413 and thefourth side 414 both form an angle of 60 degrees to thefirst side 411. Two reflectors (not shown) are respectively installed on thethird side 413 and thefourth side 414. Thesecond side 412 is located between thefirst side 411 and thelens module 12. Theprism 41 is driven by a motor (not shown) installed in the automobile to move back and forth. A cycle of moving theprism 41 is equal to or less than 0.02 seconds. - In use of the
monitor 200, the motor is turned on to drive theprism 41 move back and forth. When theprism 41 moves to a first place where thethird side 413 is located in an incident light path of thelens module 12, optical image signals in a range covering a visual angle of 30 to 90 degrees in one side according to the direction in which the automobile is reversing are reflected into the visual field of thelens module 12 by the reflector on thethird side 413. When theprism 41 moves from the first place to a second place where thesecond side 412 is located in the incident light path of thelens module 12, optical image signals in a range covering a visual angle of 30 degrees in left or right according to the direction in which the automobile is reversing travel through thefirst side 411 and thesecond side 412, then thelens module 12 receives the optical image signals. When theprism 41 moves to a third place where thefourth side 414 is located in the incident light path of thelens module 12, optical image signals in a range covering a visual angle of 30 to 90 degrees in another side according to the direction in which the automobile is reversing are reflected into the visual field of thelens module 12 by the reflector on thefourth side 414. - The optical image signals coming from above three positions all covering a visual angle of 60 degrees are received by the
lens module 12, and arrive at theimage sensor 11. Theimage sensor 11 transforms the optical image signals into electronic image signals and transfers the electronic image signals to thedisplay 30. Thedisplay 30 transforms the electronic image signals into a panoramic image covering a visual angle of 180 degrees behind the automobile. A moving cycle of theprism 41 is not more than 0.02 seconds, i.e. less than the time of visual persistence. Before a panoramic image disappears displayed on thedisplay 30 in the driver's eyes, it is replaced by a next panoramic image that comes from the optical image signals received by thelens module 12 after theprism 41 moves back and forth. In this way, changing of the panoramic images caused by rotating themirror 21 can not be sensed by the driver's eyes. Therefore the driver sees that the panoramic images covering a visual angle of 180 degrees behind the automobile are continuously displayed on thedisplay 30. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
