1. A phase-detect system, comprising:

  • a first pixel as a first component of the phase-detect system;

    a first color filter formed over the first pixel;

    a second pixel as a second component of the phase-detect system, the second pixel being adjacent to the first pixel;

    a second color filter formed over the second pixel, the second color filter having a color different from a color of the first color filter; and

    a micro-lens spanning the first pixel and the second pixel, configured to capture a phase difference in spatial frequency information present in an imaged scene, the first pixel and the second pixel being placed adjacent to each other in at least one direction selected from directions including a horizontal direction, a vertical direction, and a diagonal direction, an arrangement of the two pixels being replicated in at least one interval including intervals of regular intervals and irregular intervals across the sensor.
