Disclosed is a multimedia searching method, which can achieve a high performance and provide a interoperability by defining a standard histogram that can be mutually searched, and optimizing the histogram for each application. According to the method, the histogram using uniformly quantized bin values is defined as a standard histogram, and a comparative search is performed by converting the standard histogram into an optimized histogram having non-uniformly-quantized bin values optimized for a certain application by non-uniformly combining the uniformly-quantized bin values. Also, according to the method, the histogram obtained by uniformly quantizing a given color space is defined as a standard histogram, and a comparative search is performed by converting the standard histogram into an optimized histogram having bins representing the non-uniformly-quantized color space optimized for a certain application by non-uniformly combining the bins obtained by uniformly quantizing the color space into the N partial regions.
