Included are embodiments for determining an intermediate image. At least one embodiment includes receiving data associated with a first motion vector and receiving data associated with a second motion vector, wherein the first motion vector and the second motion vector define a first image and a second image. Some embodiments include determining a single set of potential pixel values for an intermediate image, the single set of pixel values being determined from the first motion vector and the second motion vector and creating the intermediate image from the single set of potential pixel values.

Determining an intermediate image

A method for dynamically adjusting video brightness performs histogram equalization on a video YUV brightness/color signal to generate an equalization brightness curve. The brightness of each pixel is compared with every pixel of the video frame before and after histogram equalization to generate a comparison difference value. The brightness of the pixel is adjusted so that the brightness difference after adjustment won't be larger than three times of the comparison difference value and won't be smaller than a fourth of the comparison difference value. The brightness of each pixel before and after histogram equalization is compared, one by one, to generate a brightness difference value. The brightness difference value is adjusted so that the brightness difference after adjustment won't be larger than a largest brightness value and won't be smaller than a smallest brightness value. The brightness of each video frame can be properly adjusted to accomplish clearer displaying effect.
