When painting using paint, you can not make colors that you think by themselves, and there are many people who have thought that "it was better to remain in line drawing ...". Good news for those who are not good at painting using such paints, Adobe Photoshop and other "Eyedropper tool"Realized in the real world,"A device that recognizes the color of an object and automatically generates its color with paints"Has appeared.

For those who are not good at color painting, it was the reason why they made a device like a dream,Department of Mechanical and Information Engineering, University of TokyoA student of. In the Department of Mechanical and Information Engineering, a third grade students have their own free ideas and exercises for planning, designing, and producing robots, software, etc. on subjects such as mechatronics and intelligent information processingVoluntary projectIt seems to be done, among which Twitter users Takahama (@ grouse324st) Created this device.

I won the first prize in voluntary project of Mechanical and Information Engineering Department! ! !
It is a device that recognizes colors of surrounding objects and automatically generates that color with paints.

Appearance of the device looks like this. Four tanks containing blue, red, yellow, and black paint are carried, and from this it expresses colors with four components of cyan (blue), magenta (red), yellow (yellow), and black (black)CMYKYou can expect to adopt the method. Four tubes are extending from each tank, it seems that it does not come out with the four colors mixed together, it becomes a specified color when mixing out the paint that came out.


In fact, I succeeded in faithfully reproducing the color of notes and books.



In addition, the appearance of actually moving is also released in the movie.

I am surprised that the response is big!
I have some moving movies, so I will post thempic.twitter.com/Adv9B7PyIa

First we read the color from the real world object with a white cylindrical device.


Then, the color read can be used on the PC.


Next, paint comes out from the tube of the device.


When multiple colors mix ......


It faithfully reproduces the color that I read with this kind of feeling.


You can see that the colors printed on paper, the colors displayed on the PC's display, and the colors of the paints all have similar colors.


According to the producer Takahama, the one used for color reading is commercially availableInexpensive color sensorIn the color you readConvert RGB to CMYKIt seems to be doing.
