Canon Files Patent To Reduce Noise And Aliasing

2013_12850_fig02-fd920

 

Another patent spotted by Egami (translated). Canon filed a patent to reduce sensor noise and aliasing by better processing the sensor output.

  • Patent Publication No. 2013-12850
    • 2013.1.17 Release Date
    • Filing date 2011.6.28
  • Traditional thinning processing
    • Sensitivity for color signal is lower than the luminance signal, the human visual characteristic is not a problem even if thinned out color signals
    • If the algorithm requires a memory, in terms of response and undesirable Continuous
    • Frequency band of brightness and color are different, depending on the algorithm, causes color streaks
  • Canon patent
    • By aligning the frequency band decimation and interpolation processing to the luminance signal, suppress the color stripes
    • Do to reduce the amount of data to be converted from YRB RG1G2B, decimating the RB
      • Each frequency band is divided into storage (YRB1 ~ YRB4)

Canon EF 24-70mm f/4L IS USM Review (Photography Blog)

Canon EF 24-70mm f/4L IS USM Review

The [shoplink 8251]Canon EF 24-70mm f/4L IS USM (price & specs)[/shoplink] is the standard choice for many pros using Canon full-frame cameras. The lens has image stabilization, macro features and an ultrasonic motor for AF. Although it has a price tag of $1499 it is still cheaper than the heavy discussed [shoplink 2160]Canon EF 24-70mm f/2.8L II USM (price & specs)[/shoplink], which comes at $2199. If you can live without the f/2.8 (but there is Canon’s excellent IS instead) this lens may be the right glass on your full-frame DSLR (like the entry level [shoplink 7139]Canon EOS 6D (price & specs)[/shoplink], the cam used to test the 24-70 f/4).

Photography Blog reviewed the 24-70 f/4 posting an exhaustive review (check the various sections about the lens’ sharpness, samples images here). In the conclusion they write (emphasis mine):

Given its L-series billing, the Canon EF 24-70mm f/4L IS USM build quality is reassuringly excellent and it makes a perfect partner to a full-frame Canon DSLR like the EOS6D that we tested it with. Auto-focusing is quiet and quick, with the ability to manually override it and focus manually if required proving a nice touch. The capable image stabilisation system used in conjunction with a high-ISO monster like the 6D is a low-light shooter’s dream ticket, making it easy to hand-hold the camera and get the shot, despite the relatively slow maximum aperture of f/4.

Canon EF 40mm f/2.8 STM DxOMarked (very sharp!)

Canon EF 40mm f/2.8 STM DxOMarked

DxOMark analyzed the [shoplink 5686]EF 40mm f/2.8 STM (price & specs)[/shoplink] using a [shoplink 254]EOS 5D Mark II (price & specs)[/shoplink], and the nifty pancake got figures:

Considering its relatively low price, the EF 40mm f/2.8 STM was a solid performer on our DxOMark Camera Lens Ratings. […] it rates among the top seven standard prime lenses (with a focal range between 35mm and 85mm) achieving an overall DxOMark Score of 26.

Strengths of the Canon EF 40mm f/2.8 STM include resolution […] Additionally, our sharpness measurements and field maps […] indicated that the lens delivered relatively consistent edge-to-edge sharpness from f/2.8 to f/11.

Other strengths include its low geometric distortion and well-controlled chromatic aberration as indicated by its low Chromatic Aberration score of 10µm.

The one weakness of the Canon EF 40mm f/2.8 STM was the strong vignetting evident at the widest apertures. You can see from the vignetting field maps below that at f/2.8, there is heavy shading across 2/3 of the field.

The Canon EF 40mm f/2.8 STM actually has price tag of $149. A bargain for a lens that has such a good perfomance (click on shop name): [shopcountry 5686].

The 40mm pancake performs slightly better than the much pricier Canon [shoplink 175]EF 50mm f/1.4 USM(price & specs)[/shoplink], and the cheaper [shoplink 173]EF 50mm f/1.8[/shoplink]. As you can see, all three lenses have very good sharpness figures.
