![]() ![]() This is why a lot of premium dash cams often perform even better than premium action cameras in low-light situations. For the best results, the engineers need to spend time not only coding but also testing in real-life situations, gather their findings and further improve their algorithms.Ī good dash cam will generally be tuned to produce useful footage in a wide range of lighting situations, including at night. They do so by applying noise reduction, color correction and a multitude of other tweaks. ISP tuning is the process by which engineers take the raw image output by the sensor and convert it into the final image produced by the camera. That’s why image signal processor (ISP) tuning is becoming more and more important to extract the best results out of any chip and sensor combination. However, as the available light goes down or the action speeds up, blurriness will always become an issue. Even the cheapest cameras nowadays can capture decent footage in bright daylight. The truth is, out of the box, even the best CMOS sensors from the most reputable manufacturers can produce subpar results if they are not tuned properly. However, one of the common misconceptions about video quality is that if you are using a good lens, sensor and processor, you will mechanically end up with good image quality. Oh, and of course, these components need to be somewhat affordable enough for a consumer-level product. Then the processor needs to be efficient and generate as little heat as possible as well. ![]() The lens should have a wide-enough view angle to cover the action without introducing too much distortion or blur. When it comes to image quality, this means choosing a sensor that will have high enough resolution but also good low-light sensitivity, all in a small form factor and without generating too much heat. It goes without saying that selecting the best components for the job is a crucial part of building a quality dash cam. ![]() Image quality (hardware + ISP tuning) Quality hardware components: lens, sensor, processor. why alternatives like action cameras may not be ideal to use as a dash cam.what goes into the development and manufacturing of a premium dash cam, such as a BlackVue.Or perhaps you are thinking about using an action camera or an old phone instead of a dedicated dash cam? In this article, we will cover: One of the most common comments we get here at BlackVue is “why does this dash cam cost this much? I found one on Amazon for $30!”. ![]()
