Learn about 12-bit integers, memory addresses, or other data units that are 12 bits wide. Find out the history and examples of 12-bit CPU, ADC, and microcontroller architectures.
With 12-bit resolution, $2^{12}= 4096$ different numbers can be represented, this means that the measuring range of a given sensor gets split into 4096 pieces. As an example, if your sensor can measure from 0V to 409.6V (just for nicer math), then with 12-bit resolution, you can resolve the measured value in increments of 0.1V.
While the video above is tailored more towards video, the same holds true for stills. This is why we've seen the progression from 10Bit RAW files to 12Bit, with 14Bit now the standard amongst most medium-to-high end DSLRs and mirrorless cameras. 14Bit, by the way, can contain over 4 trillion different colours and shades.
What is 8-bit, 10-bit and 12-bit color depth? Color depth is also known as bit-depth which refers to the number of bits used to define the color channels, red, green or blue, for each pixel. In most RGB systems, there are 256 shades per color channel. If you know binary system well enough, this number 256 should sound very familiar to you.
OK, you're conflating a lot of things here. 8-bit, 10-bit and 12-bit refer to your color depth.With RGB color each value (red, green, and blue) is stored using a unit that is measured in bits.. Quick background on this: a bit is the smallest digital unit of storage, it's a binary unit, either 1 or 0.. So with an 8-bit color depth you have 8 bits to describe how red a pixel is, 8 bits to ...
Example Calculation for 12-bit ADC. For example, if an 12-bit ADC has a reference voltage (Vref) of 5V, the smallest change it can detect (quantum) is Vref / 2 12 = 5V / 4096 ≈ 1.22 mV. This means each step of the digital output corresponds to a change of about 1.22 mV in the input signal.
Learn how bit depth affects the number of colors and brightness levels that a display can show, and why 12-bit color is better for HDR than 10-bit color. Find out the differences between HDR10, Dolby Vision, and other standards, and how they use bit depth to avoid banding.
12-bit means 4096 possible values. Assuming the same input range, we now get 1.25 mV resolution. That's obviously much better. Critics argue that one is not able to utilize the full 12-bit in a real world application due to quantization noise among other things.
But, in most other commercial clips I did some testing, I found that 12bit encoding gives better results (smaller size AND better VMAF). It goes without talking that they both are better than 8bit encoding of those 8bit source videos. If you go to 10bit source videos, 12bit encoding also gives better results than 10bit encoding.
Figure 6: 12-bit vs. 24-bit color In real world content on most 8-bit per color displays, you might perceive bit-depth banding issues in the transitions of light levels and colors in a sunset, or in the different hues of blue in a sky. Other bit-depth artifacts can be seen around the edges of objects, such as the transition between a planet in ...
