A bookmark is provided to collect main contents when a user comes back home, even though he/she reads a book not in his/her home. A bookmark is used while a user reads a book and comprises a power supply unit(106), a frame(101), a transparent window(107), an image sensor(102), a lighting device(103), a memory(104b), a user input portion, a wire communications part(111), a wireless communications unit(105a), an antenna(105b), a display device and a main controller(104a). The image sensor generates video data according to the amount of light coming through the transparent window from the outside. According to command data from the user input portion, the main controller stores video data from the image sensor in the memory. |
