A control information decoding section () decodes sets of control information contained in a stream. Further, a random access information analyzing section () carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section () generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (). Then, the management information thus generated and the stream are recorded onto a storage medium (). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.

A light emitting device provided with a plurality of types of light sources having different light emitting colors and with a light emission control means for allowing light to emit, during a specified period of monitoring a light emitting intensity, from at least one light source out of the plurality of types of light sources at a light emitting intensity different from that available outside the specified period. Accordingly, when a plurality of types of light sources are used, the light emitting intensities of a plurality of types of light sources can be monitored with light sensors of types fewer than the types of light sources to control while points and a brightness characteristics.

A saturation detecting means () detects saturation at every pixel in a digital color image or at every coordinate point in an analog color image. A saturation conversion control means () determines the saturation conversion condition for the pixel or coordinate point based on the detected saturation. A saturation conversion processing means () implements saturation conversion in such a manner that saturation is reduced for the areas with low saturations in the color image, so as to enlarge the difference in saturation relative to the areas with high saturations, thus achieving improved saturation contrast. Further, the distribution of saturations in the input image is automatically extracted, so as to determine the threshold for deciding a saturation suppressed area based on the distribution of saturations. In this way, in order to obtain a color image improved in vividness and presenting feeling of sharpness, the saturation contrast is automatically improved.
