摘要： Various implementations relate to providing a pictorial summary, also referred to as a comic book or a narrative abstraction. In one particular implementation, a first portion in a video is accessed, and a second portion in the video is accessed. A weight for the first portion is determined, and a weight for the second portion is determined. A first number and a second number are determined. The first number identifies how many pictures from the first portion are to be used in a pictorial summary of the video. The first number is one or more, and is determined based on the weight for the first portion. The second number identifies how many pictures from the second portion are to be used in the pictorial summary of the video. The second number is one or more, and is determined based on the weight for the second portion.
