- Moiré effect
The moire effect is a disruptive phenomenon that can degrade the quality of images captured by digital cameras. It can also occasionally occur in television broadcasts. This effect arises when a regular pattern of the camera's sensor array or the display pixels interferes with a regular pattern on the display surface (for example, the texture of a fabric). The overlapping of two similar but misaligned regular patterns results in the creation of a set of patterns known as the moire effect, which manifests as colored stripes or circles.
What is the Moire Effect?
The moire effect occurs when we perceive interference between two grids of lines arranged at different angles or sizes. This means that it results from the overlapping of two different patterns of lines or shapes, creating an undesirable visual effect that cannot be removed.
While the moire effect is less noticeable in analog photographs, it is particularly pronounced in digital photography. This is due to the very nature of the digital camera sensor, which is essentially made up of a grid of pixels.
