摘要 |
For improving picture quality in auto-focus control, image processing device 10 adjusts output picture imaged by image pick-up element 4 and displayed by a display section, comprises storage section 13 for storing predetermined de-focus threshold value of variation amount of intensity value of output picture; first adder section 12 for calculating intensity value time difference variation amount between intensity value of output picture being input and intensity value of the predetermined-time previous output picture before the output picture is input; and variation amount comparison section 14 for comparing intensity value time difference variation amount and de-focus threshold value, wherein when variation amount comparison section determines that intensity value time difference variation amount is less than de-focus threshold value to be a comparison object, intensity value of output picture after being adjusted is calculated by subtracting intensity value time difference variation amount from intensity value of output picture being input.
