DESCRIPTION OF THE INVENTION

(17) FIG. 1A illustrates a side view of an exemplary mobile device with a camera on the back, namely opposite from a display. The mobile device with camera 100 shown comprises both a touch display 102 in front and a camera 110 in the back. The camera 110 comprises a lens 106 and camera chip sensor 104, as shown in greater detail in FIG. 2. The camera 110 has been placed at the back of the phone to facilitate a visual of a photograph to be taken on the camera 110 via the touch display 102. In the embodiment shown, the touch display 102 consumes most of the frontal space of mobile device with camera 100. A mobile device with a touch display 102 is exemplary and is used to illustrate the structure and operations of various optical adapters. A mobile device with a non-touch screen could also use the optical adapters.

(18) FIG. 1B illustrates the back view of a mobile device with a camera 100. The mobile device with camera 100 contains a camera 110 on the back comprising a lens 106. Only the lens 106 portion of camera 110 is visible.

(19) Normal Light Input

(20) FIG. 2 illustrates normal light input into a camera lens. The rays of light 120 (a-d) shine through lens 106 and refract into the camera chip sensor 104. The camera chip sensor 104 digitizes the rays of light 120 to form a digital image, namely a photograph or a frame of video. Digitizing a digital image is referred to a capturing an image.

(21) Light Input Reflected Via Dual Mirrors and a Lens Reverser

(22) A novel aspect of the present invention is an optical adapter comprising a top mirror 140, a bottom mirror 142, and a novel lens reverser 200.

(23) The terminology “top” and “bottom” are used consistent with the drawings to identify the respective mirrors. It is understood that the optical adapters could be rotated 90, 180, or 270 degrees, relative to the mobile device such that the “top mirror” would be on the right, bottom, and left, respectively, and the “bottom mirror” would be on the left, top, and right, respectively. Such rotation would not alter the elements of the structure nor alter operation of the claimed invention.

(24) FIG. 3A illustrates a mobile device 100 with a first adapter configuration 300. The first adapter configuration 300 is placed on the back of the mobile device with camera 100 opposite the touch screen 102. The rays of light 120 shine from in front of mobile device with camera 100 into the first adapter configuration 300 where it first reflects down off of top mirror 140a and second reflects back in off of bottom mirror 142a, and ultimately enters into camera 110.

(25) FIG. 3B further illustrates the structure and operation of a novel lens reverser 200 of FIG. 3A. The rays of light 120 (a-d) shine straight through a lens reverser 200 and lens 106 respectively and are then digitized by the camera chip sensor 104 to form a digital image. The lens 106 and camera chip sensor 104 are both part of the mobile device with camera 100. The lens reverser 200 is configured to reverse the optical properties of the built-in lens 106. As shown here, the lens 106 has a convex outer surface, so to be effective the lens reverser has a precisely matching concave surface, such that in this example the light is straightened out. Once the light is straightened out it can travel any distance, from mirror to mirror, using the same lumen (or bore through a tubular adapter housing 150). In other situations, such as where the built-in lens 106 is behind a flat piece of exterior glass or plastic, the lens reverser 200 will have to be engineered to have the necessary reversing properties based on the external surface constraints and the precise distance that it will be mounted away from the refracting surface of the built-in lens 106

(26) FIG. 3C further illustrates the structure and operation of a first adapter configuration 300 of FIG. 3A. The rays of light 120 (a-d) shine from in front into the first adapter configuration 300 where it first reflects down off of top mirror 140a and second reflects back in off of bottom mirror 142a. Note that in this embodiment the mirrors are both at 45 degree angles. Next, the rays of light 120 (a-d) shine straight through a lens reverser 200 and lens 106, as a result of the lens reverser 200, and are then digitized by the camera chip sensor 104 to form a digital image. The lens 106 and camera chip sensor 104 are both part of the mobile device with camera 100. The lens reverser 200 and mirrors (140 and 142) are part of the optical adapter configuration 300.

(27) The Addition of a Re-Lens

(28) FIG. 3D illustrates a second adapter configuration such as shown in FIG. 5A through 5C. The embodiment of the second adapter configuration 310 is similar to the first adapter configuration 300 (FIG. 3C) with the addition of re-lens 210. The rays of light 120 shine through the re-lens 210, which reshapes the light for the original camera lens 106. With the first adapter configuration 300, the light gathering properties of the built-in lens 106 are reversed. In order for the standard software to work on the mobile device, it is desirable to recreate substantially the same optical characteristics of how the light is gathered. The re-lens 210 in some embodiments where the light is substantially straightened could be identical to the original lens 106. In other embodiments, it may be beneficial to slightly modify the light gathering characteristics to better facilitate the intended use, namely self-imaging or videoconferencing, which may have a preferred focal range of about 18 inches, for example, when the mobile device is held in the hand of the user.

(29) Mirror Angles can Reduce Thickness of Optical Adapter Housing

(30) FIGS. 3E and 3F illustrate alternate adapter embodiments. FIG. 3E illustrates a side view of a mobile device with camera 100 shown having a touch display 102. Both FIGS. 3E and 3F illustrate the workings and inner components of the wide adapter 400.

(31) FIG. 3E illustrates an embodiment where the rays of light 120 shine into and reflect down off of the wide top mirror 140b (angled at 145 degrees), back in off of bottom mirror 142b (angled at 55 degrees) and then into lens 106. Note that in this example, as shown, the light is gathered into the top mirror 140b at an angle that is below perpendicular to the front face of the mobile device 100. In an alternate configuration the light could be gathered at an angle that is above perpendicular to the front face of the mobile device. FIG. 3E further illustrates that unlike FIGS. 3C and 3D, the mirrors do not have to be at 45 degree angles and this allows the top mirror 140b to be position forward over the top edge of the mobile device 100. This allows the bottom mirror 142b to be smaller than the top mirror 140b, and also allows the light to be gathered into a narrower beam as it enters the adapter and reflects from mirror to mirror. This eliminates the need for a lens reverser 200 or a re-lens 210 thus simplifying the optical adapter. This embodiment may be housed in a wide adapter 400 (shown in cross section by the dashed lines; see also FIGS. 4A and 4B.

(32) FIG. 3F illustrates an embodiment where the rays of light 120 shine into and reflect down off of a wide top mirror 140c (at 150 degrees), back in off of a bottom mirror 142c at 60 degrees, then through lens reverser 200, and ultimately into lens 106. This is another example where the mirrors are not necessarily at 45 degree angles and the top mirror 140c may be forward of top edge of the mobile device 100 (not shown but indicated by the relative position of the camera chip sensor 104 and the lens 106). In contrast to the example shown in FIG. 3E, the light is received at an angle that is perpendicular to the face of the mobile device 100 (not shown). This embodiment may also be housed in a wide adapter 400 (not shown).

(33) Wide Optical Adapters for Mobile Devices with a Camera

(34) FIGS. 4A and 4B illustrate a wide adapter 400 mounted on an exemplary mobile device with camera 100.

(35) FIG. 4A illustrates a perspective front view of mobile device with camera 100. In this exemplary illustration the mobile device 100 has a touch display 102. The display 102 illustrates the mobile device 100 being used in a videoconference where the local user is facing the display 102 is able to simultaneously view both the image being transmitted and the image being received. Alternatively, the local user can be viewing more than one remote participant in the videoconference while simultaneously capturing the local image via the wide optical adapter 400. In this front view, the top mirror 140b is visualized angled over the top edge of the mobile device 100.

(36) FIG. 4B illustrates a back view of mobile device with camera 100. The wide adapter 400 mounts onto the top of the mobile device with camera 100 and houses, for example, the first adapter configuration 300 of FIG. 3C, the embodiment shown in FIG. 3E or the embodiment shown in FIG. 3F. The wide adapter 400 is shown in this example comprising a rectangular wide top mirror 140b and a smaller round bottom mirror 142b both held into position with a housing 150a. The rays of light 120 (not shown) pass through the adapter, as described above with each respective embodiment, and ultimately into the built-in lens 106.

(37) The wide adapter 400 shown in FIGS. 4A and 4B is configured to slip on and off of the mobile device 100. This allows for easy setup and use. The optical adapter can be easily transported attached to the mobile device 100, for example in a garment pocket, or holster. Alternatively it can be transported separately and removably attached when needed. The housing 150a of the wide adapter 400 protects the internal components of the optical adapter and may be configured to mate with specific mobile devices 100.

(38) Narrow Optical Adapters for Mobile Devices with a Camera

(39) FIG. 5A through 5D illustrate narrow embodiments of optical adapters for the mobile device with a camera 100.

(40) FIG. 5A illustrates a perspective front view of a narrow adapter 500 mounted on an exemplary mobile device with camera 100. In this exemplary illustration the mobile device 100 has a touch display 102. The display 102 illustrates the mobile device 100 being used in a videoconference where the local user is facing the display 102 is able to simultaneously view both the image being transmitted and the image being received. Alternatively, the local user can be viewing more than one remote participant in the videoconference while simultaneously capturing the local image via the narrow adapter 500.

(41) FIG. 5B illustrates a back view of the narrow adapter 500 mounted on the exemplary mobile device with camera 100.

(42) The narrow adapter 500 mounts onto the top of the mobile device with camera 100 and houses, for example, the second adapter configuration 310, as described in reference to FIG. 3D. The narrow adapter 500 comprises a re-lens 210, a top mirror 140a, a bottom mirror 142a, and a lens reverser 200 all held into position with a housing 150b. As shown in FIG. 5A, the re-lens 210 may be in the same plane as the display 102. As shown in FIG. 5B, in this embodiment, each of the lens 106, bottom mirror 142a and top mirror 140a are round. In this example, the top mirror 140a and the bottom mirror 142a are about the same size, which is made possible by the light straightening features of the lens reverser 200 (see FIG. 3D) and the beam being able to pass through the same sized lumen between the mirrors (140a and 142a).

(43) The narrow adapter 500 shown in FIGS. 5A and 5B is configured to slip on and off of the mobile device 100. This allows for easy setup and use. The optical adapter can be easily transported attached to the mobile device 100, for example in a garment pocket, or holster. Alternatively it can be transported separately and removably attached when needed. The housing 150b of the narrow adapter 400 protects the internal components of the optical adapter and may be configured to mate with specific mobile devices 100.

(44) FIG. 5C illustrates the front view of a side adapter 510 mounted on an exemplary mobile device with camera 100 in a landscape position. The side adapter 510 mounts onto the mobile device with camera 100 and houses, for example, the second adapter configuration 310, as described in reference to FIG. 3D. The side adapter 500 comprises a re-lens 210, a top mirror 140a, a bottom mirror 142a, and a lens reverser 200 all held into position with a housing 150c. As shown in FIG. 5C, the re-lens 210 may be in the same plane as the display 102. The landscape position allows the camera 110 (not shown) to capture images and display them at a wider angle.

(45) The side adapter 510 shown in FIG. 5C is configured to slip on and off of the mobile device 100. This allows for easy setup and use. The optical adapter can be easily transported attached to the mobile device 100, for example in a garment pocket, or holster. Alternatively it can be transported separately and removably attached when needed. The housing 150c of the side adapter 510 protects the internal components of the optical adapter and may be configured to mate with specific mobile devices 100. The side adapter 510 reduces the overall length of the combined system comprising the mobile device 100 and the side adapter 510, when compared to the wide adapter 400 shown in FIG. 4A or the narrow adapter 500 shown in FIG. 5A.

(46) FIG. 5D shows an adjustable adapter 520 which is be mounted on a mobile device with a camera 100. The adjustable adapter 520 may comprise, for example, the second adapter configuration 310, as described in reference to FIG. 3D. The adjustable adapter 520 may comprise a re-lens 210, a top mirror 140a, a bottom mirror 142a, and a lens reverser 200 all held into position with a housing 150d. The adjustable adapter 520 can be positioned in either a vertical or horizontal position. In one embodiment, it may be attached with a swivel attachment allowing it to be rotated 90 degrees by the user. Once positioned it may alternatively be held in place by a flexible cover, such as a rubberized skin or leather case (not shown).

(47) Adapters for iPhone G3

(48) After my initial drawings for optical adapter, Apple released a new version of the iPhone, the iPhone G3, which has a few notable features including locating the camera 110 in a corner on the back and various buttons/toggles 602(a-c) at the top and side. FIG. 6A through 6E illustrate alternate embodiments of optical adapters for, but not limited to, the iPhone 600. The optical adapters are not limited to the iPhone, and may be used or modified for use with other mobile devices with cameras available now and in the future.

(49) These adapters can be easily applied to and removed from the mobile device with a camera, such as an iPhone, or iPhone-like device. Application for these adapters may be performed directly over an existing skin, cover, or protector so that the existing skin does not have to be removed for videoconferencing use.

(50) FIG. 6A shows an iPhone 600 with an optical adapter having a second adapter configuration 310 (in a housing 150d, not shown, similar to adjustable adapter 520), held in place by a horizontal casing 610 which clips over the upper left corner and reaches out between the buttons/toggles 602(b-c) on the side. In addition, cutouts provide access and operation of the button/toggle 602a on the top.

(51) FIG. 6B shows an iPhone 600 with an optical adapter having a second adapter configuration 310, held in place by a vertical casing 620 that clips over the upper left corner and reaches down to the bottom. In addition, cutouts provide access and operation of the button/toggle 602a on the top.

(52) FIG. 6C shows an iPhone 600 with an optical adapter having a second adapter configuration 310, held in place by a diagonal casing 630 that clips over the upper left corner and reaches down over the bottom right corner. In addition, cutouts provide access and operation of the button/toggle 602a on the top.

(53) FIG. 6D shows an iPhone 600 with an optical adapter having a second adapter configuration 310, held in place by a full casing 640 that clips over the entire iPhone 600 (over all 4 corners). The entire front of the iPhone 600, including touch display 102, is uncovered and operational. In addition, cutouts provide access and operation of the buttons/toggles 602(a-c).

(54) FIG. 6E shows an iPhone 600 with an optical adapter having a second adapter configuration 310, held in place by an adjustable casing 650 which clips over the upper left corner and moveable arm 652 reaches out between the buttons/toggles 602(b-c) and clips along the sides and front. The spring 656 inside the adjustable casing 650 provides the inward tension to keep the adapter firmly in place. This allows the adjustable casing 650 to fit over an existing cover or skin, and allows the adjustable casing to fit directly on the mobile device (e.g. iPhone 600). The thumb knob 654 provides leverage to allow the moveable arm 652 to be pulled open and have the adjustable casing removed. In addition, the buttons/toggles 602(a-c) are unobstructed.

(55) The various casing embodiments can be made of rigid plastic or metal. Alternative they can be molded of soft plastic or silicon and configured to go over a plastic or metal housing 150d. Still another alternative is for the casing to be made of leather with appropriate internal or edge reinforcements.
