    • In order to enable playback of a moving image in a variable manner according to desired weight, a desired threshold value of weight is obtained for a moving image regarding which a distribution of the weight at each point on a time axis has been generated. A time range extraction unit extracts all time ranges as high weight ranges wherein the weight is equal to or higher than the threshold value in the distribution. A representative image generation unit generates representative images that respectively represent the moving image in all the extracted time ranges. A display control unit displays a catalog of the representative images so as to enable playback of the moving image from the time range corresponding to a desired one of the representative images through selection of the desired representative image.

    • A liquid crystal device is constituted by a chiral smectic liquid crystal to form a plurality of pixels. The chiral smectic liquid crystal has a temperature-dependent tilt angle characteristic satisfying the following relationship: Ĥ10−Ĥ1≦4.0 degrees, wherein Ĥ10 denotes a tilt angle at a temperature which is 10° C. lower than an upper limit temperature of chiral smectic C phase and Ĥ1 denotes a tilt angle at a temperature which is 1° C. lower than the upper limit temperature. The liquid crystal is aligned to provide an average molecular axis to be placed in a monostable alignment state under no voltage application, is tilted from the monostable alignment state in one direction when supplied with a voltage of a first polarity at a tilting angle which varies depending on magnitude of the supplied voltage, and is tilted from the monostable alignment state in the other direction when supplied with a voltage of a second polarity opposite to the first polarity at a tilting angle, said tilting angles providing maximum tilting angles formed under application of the voltages of the first and second polarities, respectively, different from each other,and one of said tilting angles continuously changing depending on magnitude of the supplied voltage of the first polarity or the second polarity.
