Claim One:
1. An image output apparatus, comprising: a first synthesis processor configured to read a plurality of designated input images from an external storage area storing the plurality of input images, generate a first synthetic image for display through a synthesis process of causing one of the plurality of read input images to be superimposed on any other one of the plurality of read input images, and output the first synthetic image; a second synthesis processor configured to generate a second synthetic image for synthesis through a synthesis process of causing the plurality of designated input images to be superimposed on any other one of the plurality of input images included in the first synthetic image and cause the second synthetic image to be stored in the external storage area; and an image selection controller configured to instruct the second synthesis processor to generate the second synthetic image including the plurality of input images selected based on input image information that is input, select whether or not the second synthetic image is used as one of the input images used to generate the first synthetic image based on the input image information, and instruct the first synthesis processor to generate the first synthetic image including the plurality of selected input images, wherein the image selection controller includes an image selector configured to select the plurality of input images to be included in the first synthetic image based on information of the plurality of input images used for generation of the first synthetic image, the information being included in the input image information, and select the input image having a low update frequency satisfying a predetermined condition among the plurality of input images to be included in the first synthetic image based on information of an update frequency corresponding to each of the input images, the information being included in the input image information, and wherein an instruction to generate the second synthetic image by performing the synthesis process on the plurality of input images having the low update frequency selected by the image selector is sent.
