Abstract
There is provided a method including obtaining an initial spatial coordinate of a pixel of an image to be projected. The method may also include generating a pre-warped spatial coordinate associated with the initial spatial coordinate. The pre-warped spatial coordinate may be calculated as a sum of a value of a warp path function at the initial spatial coordinate and a delta. Moreover, the method may include outputting the pre-warped spatial coordinate.

A method comprising:
- generating a first pre-warped spatial coordinate associated with a first initial spatial coordinate of a set of initial spatial coordinates of a pixel of an image to be projected using a first function, the first function comprising a sum of:
- a value of a first warp path function at the first spatial coordinate, the first warp path function being selected based on a value of a second initial spatial coordinate of the set of initial spatial coordinates;
- and
- a first delta;
- and
- outputting the first pre-warped spatial coordinate.

A method comprising:
- obtaining an initial spatial coordinate of a pixel of an image to be projected, the initial spatial coordinate associated with a first temperature associated with an image projection device to project the pixel;
- obtaining a second temperature associated with the image projection device;
- generating a pre-warped spatial coordinate of the pixel associated with the initial spatial coordinate, the pre-warped spatial coordinate calculated based on a temperature change between the second temperature and the first temperature and a temperature deviation function;
- and
- outputting the pre-warped spatial coordinate.
