1. A non-transitory computer readable medium, storing an information processing program therein which is to be executed on a computer in which a processing for a stored moving image and a processing for a stored sound to be synchronously played with the moving image are executed, wherein the information processing program causes the computer to execute as a plurality of units including: a moving image editing point setting unit which is configured to set, as a moving image editing point for a moving image, a point of time included in a play-section of the moving image, wherein the point of time set as the moving image editing point by the moving image editing point setting unit is at a time subsequent to storage of the moving image; a still image data extraction unit which is configured to extract a still image data corresponding to an image outputted at the moving image editing point set by the moving image editing point setting unit; a moving image editing point determination unit which is configured to determine whether or not the moving image editing point set by the moving image editing point setting unit is within a voiced sound section, wherein the voiced sound section is a section in which a voice sound is within the sound to be synchronously played with the moving image and which includes a voiced sound start point as a start point of the voiced sound section and a voiced sound end point as an end point of the voiced sound section; a sound acquire unit which is configured to acquire a plurality of sound data, each corresponding to a sound from the voiced sound start point to the voiced sound end point, regarding a plurality of pieces of the voiced sound section, respectively, in the play-section of the moving image, wherein the plurality of voiced sound sections include a first voiced sound section and a second voiced sound section; wherein the first voiced sound section is determined by the moving image editing point determination unit as the moving image editing point is within the first voiced sound section; wherein the second voiced sound section is different from the first voiced sound section, the second voiced sound section is a voiced sound section of which a voiced sound start point is within a period from a voiced sound editing point that is a voiced sound start point of the first voiced sound section until a predetermined elapsed period of time after the voiced sound editing point; and wherein the sound acquire unit is configured to acquire the plurality of sound data, even when the voiced sound end point of each of the voiced sound sections is not within a period from the voiced sound editing point until the predetermined elapsed period of time after the voiced sound editing point; a text extraction unit which is configured to extract a plurality of texts converted from the plurality of sound data, respectively, acquired by the sound acquire unit; and a combined data preparation unit which is configured to prepare a data for generating a text-combined still image in which the plurality of texts extracted by the text extraction unit are combined into a still image based on the still image data extracted by the still image data extraction unit.
