Abstract
An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.
Claims16
An image projection device for use with a mobile device having a camera flash, the image projection device comprising:
- a body defining an aperture, the body having an attachment mechanism to attach to the mobile device with the aperture positioned to receive light from the camera flash;
- a slide frame receiving slot within the body, the slide frame receiving slot is positioned to receive a slide frame in such a way that a slide on the slide frame is positioned in the aperture such that illumination of the camera flash transmits light along the aperture and through the slide;
- a magnifying lens positioned distally relative to the slide frame receiving slot to receive light from after having passed through and to project said light from after having passed through the slide;
- and
- a flash conditioner in the aperture and opposite the magnifying lens with respect to the slide frame receiving slot.
An image projection device for use with a mobile device having a camera flash, the image projection device comprising:
- a body defining an aperture, the body having an attachment mechanism to attach to the mobile device with the aperture positioned to receive light from the camera flash;
- a slide frame receiving slot within the body, the slide frame receiving slot is positioned to receive a slide frame in such a way that a slide on the slide frame is positioned in the aperture such that illumination of the camera flash transmits light along the aperture and through the slide;
- and
- a magnifying lens positioned distally relative to the slide frame receiving slot to receive light from after having passed through and to project said light from after having passed through the slide,
- wherein the attachment mechanism is any one of a clamp or a butterfly clip.
An image projection device for use with a mobile device having a camera flash, the image projection device comprising:
- a body defining an aperture, the body having an attachment mechanism to attach to the mobile device with the aperture positioned to receive light from the camera flash;
- a slide frame receiving slot within the body, the slide frame receiving slot is positioned to receive a slide frame in such a way that a slide on the slide frame is positioned in the aperture such that illumination of the camera flash transmits light along the aperture and through the slide;
- and
- a magnifying lens positioned distally relative to the slide frame receiving slot to receive light from after having passed through and to project said light from after having passed through the slide,
- wherein the slide frame receiving slot has a flexible detent projection, the flexible detent projection positioned for interacting with a notch on the slide frame to align the slide frame within the aperture.
A method of operating an image projection device in association with a mobile device having a camera flash, the image projection device including a body having a slide frame receiving slot for receiving a slide frame that contains a plurality of slide transparencies and encoding information associated with the at least one of the plurality of slide transparencies, an aperture that is positionable to receive light from the camera flash and transmit the light through at least one of the slide transparencies, and a lens positionable to project the light transmitted through the at least one of the slide transparencies, the method comprising:
- positioning the slide frame such that a first slide transparency from the plurality of slide transparencies is positioned for light transmission therethrough in the aperture;
- detecting first encoding information associated with the first slide transparency;
- emitting from the mobile device, based on the first encoding information, a first output selected from the group of output consisting of:
- audio output and visual output;
- positioning the slide frame such that a second slide transparency from the plurality of slide transparencies is positioned for light transmission therethrough in the aperture;
- detecting second encoding information associated with the second slide transparency;
- and
- emitting from the mobile device, based on the second encoding information, a second output selected from the group of output consisting of:
- audio output and visual output, wherein the second output is different than the first output.
A combination for use with a mobile device having a camera flash, comprising:
- a slide frame, wherein the slide frame a first side, a second side and an edge, and has a plurality of slides thereon;
- and
- an image projection device including:
- a body defining an aperture, wherein the body is attachable to the mobile device with the aperture positioned to receive light from the camera flash;
- a slide frame receiving slot within the body, the slide frame receiving slot is positioned to receive the slide frame in such a way that one of the slides on the slide frame is positioned in the aperture such that illumination of the camera flash transmits light along the aperture and through the slide, wherein at least one of the first and second sides of the slide frame has a plurality of features thereon each of which can mate with a corresponding feature in the slide frame receiving slot to align the slide frame in such a way that one of the slides on the slide frame is positioned in the aperture such that illumination of the camera flash transmits light along the aperture and through the slide;
- and
- a magnifying lens positioned distally relative to the slide frame receiving slot to receive light from after having passed through and to project said light from after having passed through the slide.
