Abstract: This disclosure provides systems, methods, and devices for image signal processing that support compression of phase detection (PD) data. In a first aspect, a method of image processing includes receiving image data and first phase detection data corresponding to the image data; determining a first channel of the first phase detection data and a second channel of the first phase detection data; and coding the first phase detection data to determine second phase detection data by separately coding the first channel and the second channel. Other aspects and features are also claimed and described.

Abstract: Techniques are described herein for processing image data. For instance, a technique can include obtaining a first image having a first exposure time and a second image having a second exposure time that is greater than the first exposure time. The technique can further include determining at least one of: that a first pixel of the first image has a first pixel value below a first threshold value; or that a second pixel of the second image has a second pixel value above a second threshold value; suppressing at least one of the first pixel or the second pixel based on the determination so as to prevent storing the first pixel or the second pixel; replacing the suppressed first pixel or second pixel based on a another pixel value; and outputting the first image or the second image, the first image or the second image including the another pixel.
