    Abstract: An image processing device comprises an image sensor including unit groups comprising a reference group and a conversion group each including pixels and color filters, and is configured to generate image data using the pixels, and an image signal processor which is configured to calculate a hash of the image data, and to select a filter corresponding to the hash to perform filtering, wherein the image signal processor includes a pixel index converter which is configured to convert indexes of the pixels based on a positional relationship between the pixels, a pixel property converter which is configured to convert the properties of the pixels and to convert the hash before conversion, and a filter coefficient converter which is configured to convert filter coefficients of the pixels based on the respective converted pixel index and the respective converted pixel property.

    Abstract: An image processing device includes a first wide dynamic range (WDR) image generation block, a control signal generator, and a second WDR image generation block. The first WDR image generation block processes a long-exposure image signal to generate a first image signal, processes a short-exposure image signal using a second weight value to generates a second image signal, and to synthesize the first image signal and the second image signal to generate a first WDR image signal. The control signal generator calculates a difference between the second weight value and a reference weight value and generates control signals according to a result of the calculation. The second WDR image generation block adjusts a noise level of the first WDR image signal using the control signals and generates a second WDR image signal according to a result of the adjustment.
