There were several methods of conception in seeking a visul idea of the advertising design. However, such conventional methods had a tendency that the degrees of utilization and satisfation are lacking. Also, in a thumbnail sketch phase, there was a great tendency to seek an idea based on pictorial elements only and thus depended chiefly on the existing references. Accordingly, originality was not high. Further, under the background which any common methods of a designer and a copywriter, if they have effective. I would like to propose a visul idea conception method, a condensing & amplification method for maintaining a logical system of advertising intelligence and for facilitating creative visualization through a language-oriented approach. The condensing & amplification method is the method of conception, in which after an appeal point as per advertising intelligence is passed through sentence and phrase and then condensed with word, various variation for the word develop, and by selecting the most creative word of the results, the thumbnail sketch commences based on the results amplified with the phrases and sentences.
