News Shooter: The Problem With Resolution

https://www.newsshooter.com/2020/11/26/the-problem-with-resolution/

“The recent announcements of some very high-resolution cameras have prompted fierce discussions on the nature of resolution. Sensor patterns, interpolation, compression, and many other factors all play into our understanding of resolution far beyond the simple count of photosites that usually marks the beginning and the end of the conversation about a camera’s resolution….”

Sony: IMX294CJK Diagonal 21.63 mm (Type 4/3) Approx. 10.71M-Effective Pixel Color CMOS Image Sensor

https://www.sony-semicon.co.jp/products_en/new_pro/may_2017/imx294cjk_e.html

“Sony Semiconductor Solutions Corporation has commercialized the “IMX294CJK” Type 4/3 back-illuminated CMOS image sensor with approximately 10.71M-effective pixels for the expanding security camera market.

The “IMX294CJK” is the first in-house image sensor for security cameras to adopt the Type 4/3 format, and realizes output of the number of pixels needed for 4K at 120 frame/s (in ADC 10-bit output mode). In addition, use of a large-size pixel achieves SNR1s of 0.14 lx*1, and use of a Quad Bayer pixel structure (see Figure 1) realizes an HDR (High Dynamic Range) function with no time difference, enabling video imaging with a wide dynamic range….”

“The IMX294CJK uses a Quad Bayer structure, and outputs data binned in 2 x 2 pixel units in normal mode. In HDR mode, integration can be divided into long-time integration and short-time integration for each 2 pixels in the Quad array. In this case there is no time difference between long-time integration and short-time integration, which realizes HDR with little blending offset when imaging moving subjects.”
