Abstract: A photographing apparatus includes a display unit; and a processor that is configured to acquire from a storage unit that stores information that indicates a photographed image composition for photographing a crop, information that indicates a composition determined based on information related to a farm field, the storage unit storing multiple records of the information for the crop; and display on the display unit, the acquired information that indicates the composition.

Abstract: A photographing apparatus includes a photographing unit that photographs an object; and a processor that is configured to acquire dimension information that corresponds to a type of a given crop to be photographed, from a storage unit that stores for each type of crop, dimension information that indicates a dimension to be used as a comparison reference for the crop; create based on a photographing condition at the time of photographing of the given crop by the photographing unit and the acquired dimension information, a graphic image representative of the dimension to be used as the comparison reference for the given crop, on a photographed image taken by the photographing unit; and output the photographed image taken by the photographing unit and the created graphic image in a correlated manner.

Abstract: A mobile device includes a processor; and an imaging unit that records subjects as images. The processor is configured to detect an input operation of selecting an item among a group of items representing any among an object and an event possibly motivating a recording of a subject by a person engaged in farm work, output a record instruction to the imaging unit upon detecting the input operation, correlate the item for which the input operation is detected and an image that is recorded by the imaging unit consequent to the output record instruction, and output a result of correlation.
