摘要： An accurate image interpolation method based on direction detection and device thereof are disclosed. The image interpolation method based on direction detection includes the following steps: step a, detecting an interpolating direction of a pixel to be processed to obtain interpolating direction information of the pixel; step b, utilizing the result of detecting an interpolating direction to interpolate the pixel to be processed. Another step a′ between the step a and step b is also included: utilizing the interpolating direction information of the pixel adjacent to the pixel to be processed for correcting the result of step a; at step b, utilizing the detection result of interpolating direction corrected at the step a′ to interpolate the pixel to be processed.
