1. A moving-image recording/reproduction apparatus comprising: a first image processing apparatus which is an image processing apparatus configured to divide a region of an image signal into first and second regions when the image signal of each frame in a high-resolution moving image is input and generate first moving-image data by performing moving-image processing on the image signal of the first region; and a second image processing apparatus which is an image processing apparatus configured to generate second moving-image data by performing the moving-image processing on the image signal of the second region, wherein high-resolution moving-image data corresponding to the high-resolution moving-image obtained by combining the first and second moving-image data and low-resolution moving-image data corresponding to a low-resolution moving image having the same angle of view as the high-resolution moving image generated by at least one of the first and second image processing apparatuses are associated and recorded, and wherein either the recorded high- or low-resolution moving-image data is selected according to an image resolution that is capable of being displayed by a connected display device, wherein the moving image based on the low-resolution moving-image data is generated to be displayed on the display device through either the first or the second image processing apparatus, when the moving image based on the low-resolution moving-image data is displayed on the display device, wherein a region of the image signal is divided into the first and second regions at predetermined proportions, and wherein the first image processing apparatus and the second image processing apparatus perform the moving-image processing on the image signal of a corresponding region in parallel.
