Abstract
A moving image sequence is automatically reframed for a small display. The framing is adjusted in dependence upon foreground and background segment weights derived for pixels in images in the sequence. Reframed images are formed from only those input pixels which fall within a reframing window within the input image area and the position or size of the reframing window is adjusted so as to maximize a weighted total of the sum of the foreground weights of pixels within the window and the sum of the background weights of pixels outside the window.
