Recently, in the past years, amidst the action cameras industries expanding rapidly, many manufacturers and companies are finding different ways to stay ahead and remain competitive.
Another method which I am going to discuss here would be using fake image sensors or chipsets to attract buyers.
How they go about doing it…
Most of the time, action cameras would state 12MP in their specifications or sometimes on the body itself but for cheaper action cameras, it is not the case most of the time. This is because it is actually resized or interpolated from a 4MP image sensor. Hence, if you are unsure, you can actually check the sensor datasheet to see the real image output resolution. Another thing you can do it to check the effective pixels of an image sensor. You can also feel free to ask me about the authenticity of the image sensor too.
What are effective pixels?
Effective pixels, unlike total pixels are actually the pixels the camera can see or is used for the output. Many times, action camera companies use the total number of pixels to falsely advertise for their camera, attracting more people. I can’t say that’s wrong because technically, it’s not.
Let me first explain what total pixels mean. Total pixels is the total pixels the sensor can detect, which includes pixels for both the processing of the image and also for the real output. There are pixels lined at the edge of the sensors that are unused for the capture but are used to process the image. This is there so that the camera has a reference point to an unexposed or black pixel, which then, the effective pixels can use as a reference for capture, the real output.
Hence, now you should understand why I say that using the total pixels to advertise is not technically wrong.
*Also, this is not the main ‘scam’ that companies use. The main scam is still done by interpolation or upsizing images which is mentioned above. *
Examples of these action cameras that are falsely advertised
Some examples of this would be the SJCAM M10+, Elephone Ele Explorer, F60 4K, Q3H 4K and Amkov AMK7000S 4K, which as the box or specs sheet specifies, has an output image resolution of 12MP and uses an Omnivision OV4689 image sensor. However, when you go and take a look at the sensor specs, you will realise that it is only 4MP and that this camera is falsely advertised to attract buyers to spend their money.
I know this may sound a little sketchy and a little unbelievable when I first knew about it. I also found out that many the companies that falsely advertise are actually from China and hence I can’t really fault them because the competition there is immense and they have to do everything they can to stay ahead of the competition.
Another thing to note is that although the image sensor or chipsets that they specify are false, the manufacturers are in no fault at this as it is the companies who uses these chipsets that falsely advertise.
Last but not least, I feel it is our responsibility to check more thoroughly about the product that we are going to buy before purchasing it because it is our money that we are using at the end of the day.
