Cameras Dead Pixel Test
Camera sensor dead pixels are different from display dead pixels — they appear as fixed bright or dark dots in every photo you take. Most cameras have built-in pixel mapping tools to hide them. Select your device for guidance.

NOT COVEREDSensor dead pixels show up as a bright white, red, green, or blue dot in the same position in every image. They're more common in long exposures and high ISO shots. Unlike screen dead pixels, most cameras can remap these through a built-in calibration process.
