Abstract
A system may include a display for displaying an image frame that is divided into regions having respective resolutions based on display image data. The device may also include image processing circuitry to generate the display image data based on multi-resolution image data and vignetting data generated by determining a phase offset of the pixel grouping indicative of a relative distance between the pixel grouping and a grid line of a vignetting grid and determining a relative location of the pixel grouping with respect to a set of the grid points based on the phase offset and interpolating between the vignetting values of the set of grid points to generate the vignetting data based on the relative location. The vignetting grid may include multiple grid points having corresponding vignetting values. Additionally, the image processing circuitry may apply the vignetting data to the multi-resolution image data of the pixel grouping.
