Samsung has highlighted the value of a telephoto lens in the camera of mobile phones and advocated shortening distances through the wide angle, an idea reflected in its ultra-high resolution ISOCELL sensors, which use the Remosaic algorithm to achieve similar quality achieve like telephoto shots.
The telephoto lens, when integrated into a mobile camera system, is usually present in high-end devices, usually as a supplementary sensor and not as a second main camera, as Samsung points out in its official blog.
This company argues that the telephoto lens has “become a key factor in improving smartphone camera specifications,” and one example of this is portrait photography, where, it claims, it “really shines.”
This is because the telephoto lens reduces distortion on close objects, introducing the panoramic mode used by the wide-angle lens – for large environments – and easing the blurring effect created by the focal length.
However, Samsung believes that “closing the gap between wide-angle and telephoto cameras has become a key challenge for the smartphone industry.”
In this sense, the technology company relies on ultra-high resolution ISOCELL sensors, especially those with 200 megapixels (HP2 and HP3), which use the Remosaic algorithm, which uses deep learning to improve the representation of optimized details of the scene.
These sensors shorten the distances between wide angle and telephoto. Due to their large optical format of 1/1.3 to 1/1.4 inches, they are designed as the main camera for smartphones and can capture images with improved blur. and advanced technologies such as Tetrapixel, which merges up to 16 adjacent pixels to improve image quality in low light conditions.
The company has noted that ISOCELL HP2 and ISOCELL HP3 are currently in production for use in several smartphone models, although they have not been specified. However, it was clarified that both sensors have the same key feature: a 4×4 software deep learning remosaic algorithm that enables 2x/4x lossless zoom and 4x crop zoom on-chip.
