An example of a game apparatus includes a CPU. The CPU activates two outward cameras to allow a user to image, for example, a flower. The CPU filters data for search included in a database. The CPU obtains color information, shape information and a size of the imaged flower. A shape category is obtained, and with the shape category, data for search included in a database for search is further filtered. Then, by comparing the color information, the shape information, and the size of the imaged flower with the data for search to be used, a score of a degree of approximation of the color information and scores of the degree of matching of the shape information and size, etc. are obtained. Then, images of flowers as candidates are presented in the descending order of the score (similarity level).
