Claim:
1. A content processing device comprising: a first input unit into which a first content being a moving image including a plurality of consecutive frames is input; a second input unit into which a second content being a moving image including a plurality of consecutive frames, and being different from the first content in frame rate is input; a first adjuster to adjust a frame size by enlarging or reducing the first content, and to output a first adjustment result being a result of adjustment; a second adjuster to adjust a frame size by enlarging or reducing the second content, and to output a second adjustment result being a result of adjustment; a first converter to perform first conversion processing of converting frame rates of the first adjustment result and the second adjustment result so that the frame rates become equal to each other, and to output respective results of the first conversion processing as a first conversion result and a second conversion result; a synthesizer to perform a screen synthesis for displaying the first conversion result and the second conversion result side by side on a same screen, and to output a synthesis result being a result of the screen synthesis; a second converter to perform second conversion processing of converting a frame rate of the synthesis result to a frame rate higher than the frame rate before being converted; a storage unit to temporarily store frames required for the first conversion processing and the second conversion processing during the first conversion processing and the second conversion processing; and a controller to calculate a ratio of storage capacities of the storage unit to be assigned to the first conversion processing and the second conversion processing in accordance with attributes related to motion amounts of moving images of the first adjustment result and the second adjustment result, and to perform control of assigning the storage capacities corresponding to the ratio to the first conversion processing and the second conversion processing, wherein the first converter and the second converter respectively perform the first conversion processing and the second conversion processing using the respective storage capacities assigned by the controller, wherein the attributes are frame sizes and the frame rates of the first adjustment result and the second adjustment result, wherein the first converter performs processing of converting the second adjustment result as the first conversion processing so that the frame rate of the second adjustment result becomes equal to the frame rate of the 5 first adjustment result, and wherein the controller (i) calculates a first ratio being a ratio of the frame size of the second adjustment result to a larger frame size of the frame sizes of the first adjustment result and the second adjustment result, and a second ratio being a ratio of a reciprocal of the frame rate of the second adjustment result to a reciprocal of the frame rate of the synthesis result, and (ii) calculates a third ratio obtained by multiplying the first ratio and the second ratio as the ratio.
