An image processing device is provided. The image processing device includes an image signal processor for processing a raw image received from a camera and a memory for storing a previous frame of the raw image and an intermediate image generated by the processing, wherein the image signal processor estimates an initial global motion vector between the previous frame and a current frame, receives focus region information in the raw image, divides the raw image into a foreground (FG) region and a background (BG) region based on the focus region information, generates a final global motion vector by divisionally updating the initial global motion vector based on the FG region and the BG region, performs motion compensation by applying the final global motion vector to the previous frame, and outputs a final image by blending the motion-compensated previous frame with the current frame.

A camera controller controls a camera module, which includes a plastic lens and an actuator controlling a position of the lens in an open-loop mode. The camera controller includes an offset determiner configured to determine a first offset corresponding to a measured temperature of a camera and a second offset corresponding to a measured posture of the camera, a lens moving range determiner configured to determine a moving range of the lens based on the first offset and the second offset, and an autofocus calculator configured to output a position control signal for controlling a position of the lens and seek a focus position of the lens based on the lens moving range.

An autofocus method of a camera, having an actuator controlling the position of a lens in an open-loop mode, includes receiving and analyzing an image captured using the lens and generating a face detection signal indicating whether a face is detected based on the analysis result. The size of the face is calculated when the face is detected, and a start position of the lens is determined based on the size of the face. A focus position of the lens is sought based on the start position of the lens.

A scaler is provided and includes filters each receiving input pixel data and scaling the input pixel data using a scaling factor to generate a scaled pixel value, and a plurality of mixers, less than the plurality of filters. A first mixer performs a first blending operation on a first scaled pixel value and a second scaled pixel value provided by different filters. A second mixer performs a second blending operation on the blended result of the first mixer and a third scaled pixel value provided by anther filter.
