Description

A digital imaging system for converting a film camera into a digital camera The present invention relates to a digital imaging system for converting a film camera into a digital camera, a method for capturing a digital image with a film camera using the digital imaging system, and a component kit including a digital imaging system for converting a film camera into a digital camera. Despite the widespread adoption of digital cameras today, analog film cameras are still in use, and many people enjoy taking photos with them. This is primarily due to the lack of complex exposure options commonly offered by digital cameras, combined with the challenge of obtaining good photos without the aid of digital aids such as programmed scene modes like Portrait, Landscape, and Fireworks. However, analog film and the process of developing the exposed film to obtain images are costly and cumbersome. In fact, the development of traditionally exposed film is carried out by professional shops, meaning results are obtained only after a considerable amount of time has passed since the photos were taken. Many proposals are being provided to address the aforementioned problems. For example, literature CN 2901369, WO 2023/228593 A1, and US 11,233,950 provides electronic devices for converting film cameras into digital cameras. However, these proposals are complex to handle, and realizing digital images from analog film cameras requires a large amount of energy and processing power.
