As explained above also the photo is resized from the 4MP sensor! Therefore check the sensor type. The EKEN H9 is sometimes advertised as 12MP camera, but just the max. Same applies to the Aptina ON AR0330 sensor.īe aware, often cameras are advertised as 12 MP cameras, but the Megapixel just refer to the max. take the EKEN H9 which has a 4MP sensor (Omnivision 4689), but is branded 4K. Which means if the sensor is smaller than 8MP, you can’t get a 4K video out of it. Nevertheless if you multiply the pixels you’ll get a result of about 8,8 MP (4K) or 8,29 Megapixel (UHDTV). The 16:9 format (3840 x 2160 pixels) is called UHDTV (Ultra HD). When there should be motion but 2 frames show the exact image, the frame was doubled.ĤK resolutions is 4096 x 2160 pixels and is actually not 16:9. You can’t tell from specs when browsing them, only when looking through your footage frame by frame. The output file now shows 30fps, but it looks like 15 fps. 15 frames per second are recorded and each frame is doubled. Here’s an example of a 10fps 4K video, recorded with an EKEN H9 and an early firmware:Īs mentioned at the beginning there is another trick: Doubling frames. If it is less than 24fps it will be less fluent, more likely a stop motion video. Watch out which frame rate the camera can do in 4K. So how can you check if it is a real, native 4K camera? Frame Rate If the sensor / processor is not capable of doing 4K at a reasonable frame rate, the frames are doubled to state a better figure on paper. In other words the sensor’s output is a lower resolution than 4K and then the image is upscaled by interpolation. This process works by guessing or “interpolating” values based on a weighted average of known pixels in the vicinity. Upscaling uses known pixel values to estimate unknown intermediate pixels.

Therefore the original source at a lower resolution is upscaled to achieve a 4K output file. Real 4K or native 4K is simply explained: the original source (sensor output) is 4K resolution.Īs mentioned at the beginning, “4K cameras” sell better. Find out about the difference about real vs fake 4k: Although their output video size is 4K, it might not be real 4K.

Simple reason, they sell better wearing this logo. There are a lot of action cameras branded “4K camera”.
