Samsung is working on a 200 Mpx sensor for its future ultra high-end smartphones. The particularity of this one being that it would be reserved for the telephoto lens.

On ultra-premium smartphones, if we wanted to establish a hierarchy between the photo modules, the main wide-angle sensor is often the most pampered. Then come telephoto lenses and finally ultra-wide-angle.
At Samsung for example, the wide-angle is the first to have been fitted with a 200 Mpx sensor on the Galaxy S23 Ultra. It was also he who had benefited from the 108 and 50 Mpx sensors before that. For the other sensors, nothing. Just a recent rumor claims that Samsung is considering integrating a 50 Mpx sensor into its Galaxy S24 Ultra on the X3 telephoto lens.
Samsung would be determined to get out of this rut. In blog post (since unpublished, but still visible on Internet Archive), the Korean giant has detailed a 200 Mpx sensor designed for telephoto lenses.
A telephoto lens with a bigger sensor for smaller noses
The Seoul firm first develops an argument to explain the interest in developing better telephoto lenses. She mentions in particular the distortion caused by wide angles in portraits which tends, among other things, to create big noses in photos.

Samsung explains that the main difference in quality between wide-angle and telephoto lenses, beyond the number of pixels, is to be found in the size of the sensor. The smaller the sensor, the smaller the photosites. It is therefore impossible to create a sensor with 100 or 200 Mpx starting from a sensor that is too small. However, wide-angle lenses, as Samsung writes, tend to integrate sensors of the 1/1.4 inch to one inch type while telephoto lenses are larger, of the 1/2.7 inch to 1/2 inch type.

We understand, Samsung therefore wants to improve the sensors used with its telephoto lenses. And the firm writes its project in black and white: “Image sensors currently used in wide cameras (1/1.3″ to 1/1.4″) might also be incorporated into telephoto modules in the future. » The firm further details that its sensors already used on wide angles, the SOCELL HP2 and ISOCELL HP3 are “well suited to this type of application. Although they differ in some ways, both sensors have the same main feature: a deep-learning 4×4 remosaic algorithm that enables 2x/4x lossless zoom and 4x crop zoom on-chip. »
The use that Samsung has in mind is clearly to extend the possibility of zooming in an image even further while limiting losses, thanks to the 200 Mpx. We understand this in particular in this comparison that the brand highlights between a 200 Mpx X1 sensor in which we digitally zoomed to X4 and an 11 Mpx X3 sensor pushed up to X3.9. The image below aims to prove that the loss is limited in the case of 200 Mpx.
Between the lines, we therefore believe that Samsung might be tempted to integrate a 200 Mpx sensor into a telephoto lens with a moderate zoom factor, like an X3. This would make it possible to go for an almost lossless digital X6. We are excited.
