In January, the US Patent and Trademark Office published a patent application for a “darkroom” that could “produce images and video from ambient light without a photodiode.”
The patent was for a device that “produces images and videos from ambient illumination without a camera.”
As Ars Technic reported last year, the device uses a “tungsten lamp” to “producer images and media.”
The idea is that the tungsten light can be focused into a light-sensitive lens, which can then produce “images and video without a single camera sensor.”
What’s interesting is that “a tungsterect” device could work even without a lens.
The patent suggests that the device “may be able to produce images and/or video by projecting light onto a substrate.”
A tungsteel lamp, as Ars noted, is used in “boudubos” and “cinema theaters” where the light is not focused into the lens.
The patent describes a device which produces images and movies from ambient lighting “without a camera sensor, and with a flexible surface for mounting and attaching light source.”
While that sounds interesting, it’s a lot like a “dumb phone” in that it doesn’t require a camera to produce an image.
It could also be a prototype, as the device doesn’t have a camera.
The device is described as “adaptive to ambient light conditions” and works in “natural light conditions,” but there’s no mention of what the ambient light is in this patent.
Instead, the patent describes the device as “capable of generating images and film from ambient Light without a sensor.”
This means that the patent suggests the device is not only capable of producing images, but that it can “producing images and films from ambient conditions without a digital sensor.”
As Ars notes, the idea that the darkroom can produce images from ambient sunlight without a DSLR is “a novel approach to using light sources to produce light without the need for a camera,” and it could be an interesting way to do “deep imaging.”
The device also describes how the device can be “mounted and attached to a surface.”
The concept seems promising, but it could also end up being a lot of hype.
In the US, “light-sensitive” devices have been around for a long time.
The invention described by the USPTO describes a “light sensor” that is able to “project light onto flexible substrates and light sources.”
A “light sensitive sensor” is a device capable of “projecting light onto an opaque substrate.”
The patent doesn’t specify what type of substrate or light source it uses, but the US patent application suggests that it could possibly be “a flexible substrate such as a plastic substrate, a glass substrate, or even a flexible light source like a tung steel lamp.”
The light source “can be attached to the substrate, and then when the substrate is exposed to ambient sunlight the light source can be used to generate light,” according to the patent application.
In the US of A, light-sensing devices are “technically a novel and useful application of light sensors that can be attached and attached for purposes of generating light without an electronic sensor.”
But the concept of using light sensors to produce a device without a physical camera sensor has been around since at least the mid-20th century, and it’s not something that’s likely to come up again anytime soon.
