Abstract
A method is described which better aligns the spatially dependent resolution of a sampled image sensor to the resolution requirements of an image. Most images contain greater frequency extent in the horizontal and vertical directions and therefore can benefit from higher resolution. By rotating the sampling grid of a sampled imaging sensor relative to the sampling area it is possible to better align the spatial components of the sensor which possess the highest resolution with the components of the image with the highest frequency content.
Claims12
A method for better matching the configuration of the spatial resolution pattern of an image sensor, the method comprising:
- determining a desired rotation angle of the spectrum of a two dimensional signal;
- and
- rotating the sampling grid relative to the sampling area by the rotation angle.
A method comprising organizing a sensor to sample data with greater frequency response according to nature.
