A weighing apparatus, for weighing an object, wherein the object to be weighed includes a first object to be weighed and a second object to be weighed; wherein the first object to be weighed includes a first container and a first commodity contained in the first container, the second object to be weighed includes a second container and a second commodity contained in the second container, the weighing apparatus comprising: a plurality of weighing scales (24-1 to 24-6) which are configured so that an object to be weighed can be placed thereon, and each of which is configured to measure weight of the placed object to be weighed; and a processor that is configured to calculate weight of the object to be weighed on the basis of the weight measured by each of the plurality of weighing scales (24-1 to 24-6); and a memory configured to store container data, which is data indicating the weight of first container and of the second container; the processor is configured to determine correspondence between each of the first object to be weighed and the second object to be weighed and the plurality of weighing scales (24-1 to 24-6), the correspondence indicating on which of the plurality of weighing scales (24-1 to 24-6) each of the first object to be weighed and the second object to be weighed is placed, and calculate weight of the object to be weighed on the basis of the determined correspondence and the weight measured by each of the plurality of weighing scales (24-1 to 24-6); the apparatus further comprising a camera that is configured to take an image including the first object to be weighed and the second object to be weighed which are placed on two or more weighing scales of the plurality of weighing scales (24-1 to 24-6), wherein the processor is configured to determine, on the basis of the taken image, correspondence between each of the first object to be weighed and the second object to be weighed and the plurality of weighing scales (24-1 to 24-6); and the processor is further configured to determine, on the basis of the taken image, the first container and the first commodity and also determines the second container and the second commodity, and calculate net weight of each of the determined first commodity and the determined second commodity based on container data. wherein the object to be weighed includes a first object to be weighed and a second object to be weighed; wherein the first object to be weighed includes a first container and a first commodity contained in the first container, the second object to be weighed includes a second container and a second commodity contained in the second container, a plurality of weighing scales (24-1 to 24-6) which are configured so that an object to be weighed can be placed thereon, and each of which is configured to measure weight of the placed object to be weighed; and a processor that is configured to calculate weight of the object to be weighed on the basis of the weight measured by each of the plurality of weighing scales (24-1 to 24-6); and a memory configured to store container data, which is data indicating the weight of first container and of the second container; the processor is configured to determine correspondence between each of the first object to be weighed and the second object to be weighed and the plurality of weighing scales (24-1 to 24-6), the correspondence indicating on which of the plurality of weighing scales (24-1 to 24-6) each of the first object to be weighed and the second object to be weighed is placed, and calculate weight of the object to be weighed on the basis of the determined correspondence and the weight measured by each of the plurality of weighing scales (24-1 to 24-6); determine correspondence between each of the first object to be weighed and the second object to be weighed and the plurality of weighing scales (24-1 to 24-6), the correspondence indicating on which of the plurality of weighing scales (24-1 to 24-6) each of the first object to be weighed and the second object to be weighed is placed, and calculate weight of the object to be weighed on the basis of the determined correspondence and the weight measured by each of the plurality of weighing scales (24-1 to 24-6); the apparatus further comprising a camera that is configured to take an image including the first object to be weighed and the second object to be weighed which are placed on two or more weighing scales of the plurality of weighing scales (24-1 to 24-6), wherein the processor is configured to determine, on the basis of the taken image, correspondence between each of the first object to be weighed and the second object to be weighed and the plurality of weighing scales (24-1 to 24-6); and the processor is further configured to determine, on the basis of the taken image, the first container and the first commodity and also determines the second container and the second commodity, and calculate net weight of each of the determined first commodity and the determined second commodity based on container data. determine, on the basis of the taken image, the first container and the first commodity and also determines the second container and the second commodity, and calculate net weight of each of the determined first commodity and the determined second commodity based on container data.
