Assistance device, method for assisting in design, and computer program

1 . A design assistance device comprising:

a processor programmed to:

acquire an initial image and a condition for image generation;

generate a candidate image, being a candidate of an image resulting from changing an impression of the acquired initial image;

repeatedly generate the candidate image until the generated candidate image satisfies the condition; and

cause the candidate image which satisfies the condition to be output;

wherein the condition includes a parameter item and item content regarding an impression parameter defining image impression,

the processor is further programmed to predict an impression of the generated candidate image, regarding the parameter item, and

when the predicted impression retarding the parameter item satisfies the item content regarding the parameter item designated by the condition, the processor determines that the candidate image satisfies the condition;

wherein the parameter item includes at least one or more of: valence for defining a qualitative difference of evoked emotion; arousal for defining a level of physical and cognitive arousal caused by emotion; and aesthetics for defining a level of aesthetic appearance visually sensed.

2 . The design assistance device according to claim 1 , wherein the processor further causes the predicted impression to be output, in addition to the candidate image.

3 . The design assistance device according to claim 1 , wherein

the condition includes a generation number representing a number of times the candidate image is to be generated, and

the processor repeatedly generates the candidate image until the candidate image which satisfies the condition is generated the number of times represented by the generation number.

4 . The design assistance device according to claim 1 , wherein

the condition includes item content representing a similarity level allowed between the initial image and the generated candidate image, and

when the similarity level of the generated candidate image with respect to the initial image satisfies the item content designated by the condition, the processor determines that the candidate image satisfies the condition.

5 . The design assistance device according to claim 1 , wherein the processor further causes the predicted impression to be output, in addition to the candidate image.

6 . The design assistance device according to claim 1 , wherein

in repeatedly generating the candidate image, the processor generates a plurality of candidate images that are different in impression from each other and different in impression from the acquired initial image.

7 . The design assistance device according to claim 1 , wherein

the candidate image is output so as to be displayed in association with the acquired initial image.

8 . The design assistance device according to claim 1 , wherein

the initial image is acquired from a user via designation of the initial image by the user.

9 . The design assistance device according to claim 1 , wherein

the initial image is acquired from an image database via designation of an image decision condition by a user.
