4k quality thanks to the sensor and the Chip

The undeniable quality of the image of the SJ7 Star is given by two factors: the 4K quality and the Ambarella A12 chip. An explosive combination that has turned this device into a very powerful sports camera. This chip has been created specifically to work in this type of devices oriented to the image, it manages to process 4K images (2880 x 2160 pixels) at a rate of 30 images per second.

As you can see in the video, the stability is quite good and we can see that the quality too. But it is not the only thing in this camera that improves quality, it is also incorporated with the Sony IMX117 sensor, which is the same one that has previously used the GoPro Hero 4 Black model, among other cameras of this type.

Thus, its recording capacity increases to leave behind the interpolated 4K and reach this resolution natively.In addition, the SJ7 incorporates an electronic stabilizer to capture images more smoothly and naturally.

In the case of wanting to lower this figure in order to gain fluency, it is feasible to get video in 2K (2560 x 1440 pixels) at 60 fps, Full HD 1080p (1920 x 1080 pixels) at 120/60/30 fps and 720p ( 1280 x 720 pixels) reaching up to nothing less than 200 fps.

One of the most characteristic things about this brand is that it works a lot on its designs to differentiate itself from other brands of the competition. The SJ7 Star has a rectangular format and two buttons on the front. In addition, it is incorporated with a touch screen on the back of 2 inches.
