An image sensing system includes a camera module and an application processor. The camera module includes: an image sensor including a pixel array, the pixel array including color filters having a first pattern, the image sensor being configured to sense light incident on the pixel array to generate a first pattern image signal having the first pattern; a first converter configured to convert the first pattern image signal into a second pattern image signal having a second pattern different from the first pattern; and a second converter configured to convert the second pattern image signal into a third pattern image signal having a third pattern different from the first pattern and the second pattern. The application processor is configured to perform image processing on the third pattern image signal.

Image sensing system for converting an image signal to have a specific pattern

A camera module test apparatus having improved performance include a coefficient data extractor that accommodates a camera module; and a test apparatus that accommodates the camera module and tests the camera module. The coefficient data extractor includes a coefficient generator that receives an image signal output from the camera module, and generates coefficient data of a ratio of a first color image signal and a second color image signal included in the image signal; and a memory device that stores the generated coefficient data. The test apparatus includes an image generator that receives an image signal from the camera module and coefficient data from the memory device, and generates a converted pattern image signal based on the image signal and the coefficient data; and a calibration data generator that generates calibration data of the converted pattern image signal.

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.
