Abstract
The disclosure provides a method for dynamically adjusting image clarity and an image processing device using the same method. The method includes: retrieving an image frame and searching for a predetermined object therein; evaluating a first sharpness of the predetermined object; if the first sharpness of the predetermined object is lower than a sharpness threshold, calculating a difference value between the first sharpness and the sharpness threshold; dividing the image frame into blocks and evaluating a risk value and an effect value of increasing a second sharpness of each block; inputting the difference value, the risk value, and the effect value to a classifying model to generate a clarity setting value; and adjusting a clarity of a display on showing the image frame based on the clarity setting value.
