PIXEL PROCESSING APPARATUS, AND IMAGE SIGNAL PROCESSING APPARATUS AND IMAGE PROCESSING SYSTEM EACH INCLUDING THE SAME

摘要

Provided are a pixel processing apparatus, and an image signal processing apparatus and an image processing system each including the same. The pixel processing apparatus includes a bad pixel processing unit configured to determine whether a target pixel is a bad pixel based on pixel data of an image sensor, output a bad pixel detection signal according to a result of determining whether the target pixel is a bad pixel, compensate for a pixel value of the target pixel based on the pixel data, and output the compensated pixel value; and a noise removal unit configured to remove noise from the pixel value of the target pixel, based on the bad pixel detection signal, the pixel value, the compensated pixel value, and weight information.

1. A pixel processing apparatus comprising:
a bad pixel processing unit configured to determine whether a target pixel is a bad pixel based on pixel data of an image sensor, output a bad pixel detection signal according to a result of determining whether the target pixel is a bad pixel, generate a compensated pixel value by compensating a first pixel value of the target pixel based on the pixel data, and output the compensated pixel value; and a noise removal unit configured to generate a second pixel value by removing noise from the first pixel value, based on the first pixel value, the bad pixel detection signal, the compensated pixel value, and weight information.
