Image Processing Apparatus and Method, and Program |
摘要 |
An image processing apparatus includes: a difference-value calculation mechanism calculating a difference value between the first accumulated value produced by accumulating luminance values of a plurality of pixels in a first image and the second accumulated value produced by accumulating luminance values of a plurality of pixels in a second image having a difference in time with the first image; a threshold-value creation mechanism for creating a plurality of threshold values on the difference value in accordance with the first accumulated value, corresponding to the luminance change levels in order to grade a luminance change between the first image and the second image by a luminance change level indicating a degree of the luminance change; and a luminance-change-level determination mechanism for determining the luminance change level corresponding to the difference value on the basis of the plurality of threshold values.
