Is 256 Resolution Thermal Useable? With Image Super Resolution It Is!
Author: Nicholas C
Welcome! We at DNT Optics love to share our knowledge and our experiences in hopes they may help you. When it comes to seeing in the dark, many think that higher resolution is critical, but that is not always the case. In fact, you can be successful even with lower resolution systems. In the world of thermal, some people dismiss the entry level systems like 256 thermal devices. But we want you to know they can work and work well.
Yes, 256 thermal can absolutely work, but it is dependent on the activity you are pursuing. When hunting, think of how we normally hunt in the day time. We typically scan an area with our eyeballs first. Once our eye detects something of interest, we augment our natural vision with a tool that has magnification, like binoculars. If we see the game that we are pursuing, we then transition to our weapon and use our primary aiming device.
Higher resolution thermals can produce a nicer image, but there are other factors beyond pure resolution. Base magnification is something to take into account. If you compare 1x thermal devices like 640, 384, and 256, you'll see that at a certain point, there are diminishing returns. You can only see so far with said devices even if you spend more money. However, thermal excels at showing you a difference in temperature and since it does not rely on light like night vision, it can be used in absolute darkness. Thermals are very good at detecting heat, but being able to recognize, let alone positively identify, the object you are looking at requires you to get physically closer or use magnification (optical, not digital).
Remember, thermal devices are tools, and like other tools, they have their uses. A 256 resolution thermal can have its use in your tool box. A small 1x thermal scanner is easier to scan with at night than pointing your gun and moving it around all night just to look for potential game. 256 thermal monoculars are more affordable and they can help you scan an area to detect potential game quickly. Scan a field, see anything living? No? Now you can plan your next move. On the other hand, if a 256 thermal scanner shows you something of interest, then you need to decide what your next move is. Move closer or wait for it to come closer? Or deploy a higher magnification thermal or higher resolution thermal.
Our Hydra series of thermal scopes have an AI algorithm that we call Image Super Resolution (ISR). When you turn it on, the image is sharpened. For the entry level Hydra HS219 and HS225, it enhances the image at any magnification, making a 256 sensor thermal image as clear as a 384 sensor. Higher resolution models like the HS325, HS335 or HS635 benefit from ISR only in higher magnifications. With ISR, a 384 sensor delivers clarity near that of a 640 sensor. A 640 sensor can reach an impressive 960 at its maximum magnification. Depending on the size and distance of the object you are looking at, ISR might help you see it more clearly. This gives you more confidence at long distances and helps you decide your next move. Do you continue to pursue or move on to another target?
Lower resolution thermals are not a substitute for higher resolution devices but they have their uses. They are usually more affordable and when utilized properly, they can absolutely help you on your hunt.
