摘要： Main image data pieces in a recording medium are classified into groups according to recording date and time. A digest image data piece is generated from a main image data piece or pieces in each of the groups. Each of the generated digest image data pieces represents a digest of contents of the corresponding main image data piece or pieces. Contents of the digest image data pieces are sequentially reproduced in response to user's command in an order accorded with the recording dates and times of the main image data pieces corresponding to the digest image data pieces.

摘要翻译： 根据记录日期和时间将记录介质中的主图像数据分成组。 从每个组中的主图像数据片段生成摘要图像数据片段。 每个生成的摘要图像数据片段表示对应的主图像数据片段的内容的摘要。 按照与摘要图像数据片段相对应的主图像数据的记录日期和时间的顺序响应于用户的命令顺序再现摘要图像数据的内容。

摘要： An object of the present invention is to precisely and stably detect a motion in an monitoring image, excluding effects of an illumination change and flicker. The frame division means divides an inputted X-th image frame F (X) into a plurality of blocks B(X)ij. Representative (e.g, average) luminance values BLrep (X)ij of block B (X) ij, a representative luminance value FLrep (X) of F (X), block luminance differences ΔBLrep (X)ij between the frame F (X) and a frame prior to F (X) and a frame luminance difference ΔFLrep (X) between the present frame F (X) and a frame prior to F (X) are calculated. Then, a certain block is determined to include a motion, if | ΔBLrep (X)ij−ΔFLrep (X) | for that certain block is greater than a prescribed threshold. The threshold may be adaptively changed in accordance with the luminance state.
