I received some information that a large Japanese camera manufacturer is working on a digital film (that's right, film) that can be used in traditional analogue camera equipment.
The film uses a new type of binary image sensor technology that allows images to be captured and stored on the film without the need for electrical power to retain the data. Until now, imaging sensor technology has been limited to the use of volatile memory, necessitating the use of traditional CMOS or CCD imaging sensors and storage of the captured data on internal flash drives.
Binary image sensor technology is reminiscent of traditional photographic film. Each pixel in the sensor has a binary response, giving only a one-bit quantized measurement of the local light intensity. The response function of the image sensor is non-linear and similar to a logarithmic function, which makes the sensor suitable for high dynamic range imaging.
After exposure, the film is advanced in the same way as traditional analogue film.
When the digital film has been fully exposed, the roll is removed from the camera and connected to a computer or smartphone using a USB interface. Each stored image is read out successively and sent to the computer. The film can then be 'formatted' for re-use.
One roll can hold up to 24 images, but with advances in digital film technology it is expected that higher storage capacities will become available when the film can be made thinner and wrapped more tightly.
