PROBLEM TO BE SOLVED: To provide an object detector, a learning device, and an object detection system, method, and program capable of detecting an object with a higher accuracy than in the prior art. SOLUTION: The object detector comprises a means for storing learned information having combination obtained by previously selecting a plurality of groups of a feature area having a plurality of pixel areas and quantization learned-feature quantities obtained by quantizing the learned-feature quantities as the feature quantities of the feature areas in a sample image, and information showing whether the sample image is an object or non-object. The object detector also comprises a means 201 for computing the input feature value as the feature value of the area corresponding to each feature area belonging to the combination in the input image, by determining weighted sum where each pixel area in the feature area are weighted differently or the absolute value of the weighted sum, in relation to the combination. The object detector also comprises a means 202 for quantizing the calculated input feature value and outputting the quantized input feature value, and a means 203 for determining whether or not an object is included in the input image using the quantized input feature value obtained about the combination and the learned information.
