Abstract: A method of processing image signals comprises determining whether each of multiple units of input pixel data received from an image sensor is bad pixel data generated by a bad pixel of the image sensor or normal pixel data generated by a normal pixel of the image sensor, and performing interpolation to generate image data corresponding to the bad pixel using only normal pixel data and omitting bad pixel data.

Abstract translation: 处理图像信号的方法包括确定从图像传感器接收的输入像素数据的多个单位中的每一个是由图像传感器的不良像素生成的不良像素数据还是由图像传感器的法线像素生成的正常像素数据，以及 执行内插以仅使用普通像素数据生成与坏像素相对应的图像数据，并省略不良像素数据。

Abstract: A piecewise linear processing device applies different amplification rates according to a general environment and a low luminance environment where much noise exists. The piecewise linear processing device includes a knee point storing unit configured to store a user's default setting value and low luminance setting value; a luminance detecting unit configured to detect a noisy environment to output a current luminance information signal and a maximum luminance information signal; an adaptive knee point supply unit configured to receive the default setting value, the low luminance setting value, the current luminance information signal, and the maximum luminance information signal to supply a adjusted adaptive knee point according to a degree of noise; and a piecewise linear processing unit configured to apply a section amplification rate to an input data on the basis of a region corresponding to the adaptive knee point.
