Pixel Shift Resolution

Advanced resolution technology for capturing still life subjects in ultra high definition

The in-body SR (shake reduction) mechanism is used to move the image sensor unit in minute increments, a single pixel pitch at a time, to capture four shots. Pixel Shift Resolution merges those shots into a single image to generate an ultra high-definition image. This method differs from the traditional Bayer method, which acquires only a single element of color information for single pixel, by acquiring all RGB color information for individual pixel. This difference makes it excellent for detail and color reproduction, creating super high-definition images. This also prevents false colors from occurring theoretically, and also has a high-sensitivity noise reduction effect when compared to normal shooting.

Photographed RAW images can be processed on the camera and also developed using the included utility software as Pixel Shift Resolution.

*Be sure to use a tripod for thorough stabilization when shooting.
*When shooting, use Drive Mode options: Self-timer, Remote Control, or Mirror Lock-up Shooting.
*Effects may not be gained if the subject moves or the camera shakes.

Normal shot

 


Move the image sensor unit a single pixel pitch at a time to capture four shots.

This acquires all RGB color information for individual pixel. By merging those shots into a single image, an ultra high-definition image is generated.

Pixel Shift Resolution 

Advanced resolution technology for capturing still life subjects in ultra high definition

The CMOS sensor is operated to consecutively shoot four images for individual pixel. Using the overwhelmingly large volume of color information (24M×RGB), the Pixel Shift Resolution generates a single ultra-high-definition image. The increase in resolving power and color reproducibility makes it possible to obtain such high-definition images, especially when photographing stationary subjects. Noise is also greatly reduced, and, in theory, moiré and false color are not generated. During shooting, an electronic shutter is used so camera shake can be minimized.

*When shooting please keep the camera stationary using a tripod, etc.


Pixel Shift Resolution 

Normal shot

[Color information obtained

[Color information obtained]

Four images are shot, with color and brightness information being
obtained for RGB at 24M resolution for each

For each pixel, color and brightness information is obtained for one
color only.

*High resolution and many gradations are achieved because the
image is generated using color and brightness information with
high resolving power.
*False color and color moiré are not generated because pixel
interpolation is not done.

Due to color filter RGB proportions, the resolution for each color is
1/2 for green and 1/4 for R and B.

 

[Demosaic processing]

Neighboring pixels and outlines are analyzed and missing pixel color
and brightness information is estimated (pixel interpolation).

When there are instances where the estimated color and actual color
differ, the result is false color and color moiré.

 

 *Images are for representation purpose only.

AA-filter-free 24M CMOS image sensor

Imaging element for capturing the delicate details of color and light

Approx. 24.35 effective megapixels. Under design concept to give first priority on resolution, K-3II is an AA (anti-aliasing)-filter-free model. This enables full use of the CMOS sensor’s resolving power for excellent, sharp image quality. This model can faithfully recreate the three-dimensionality and atmosphere of a scene with all of its textures. 

AA filter simulator

An unique function that prevents false colors and moiré only when necessary

The AA filter simulator realized the operation of the optical AA filter that reduces false colors and moiré, by applying microscopic vibration of the CMOS image sensor. You can select from two levels. In addition, you can set the bracket that changes the effects for capturing three successive shots.

*Effects are easily achieved when shooting at shutter speeds slower than 1/1000 sec.

*Cannot be used with some shooting modes, including Pixel Shift Resolution
