Under Use Your Image You can upload your own image (for example an screenshot of your desktop), paste an image from clipboard, put a picture url in the textbox below. Also you get the HEX color code value, RGB value and HSV value. Left button plus center button toggles volume modulation on the Y-axis. Use the online image color picker above to select a color and get the HTML Color Code of this pixel. The scrollwheel changes the frequency range and scrollwheel plus left button changes the center point of that range. The left mouse button is a momentary trigger and the right is latching.

Using the software below, the scrollwheel button switches between modes: 1 - pitch based on X-position, 2 - pitch based on camera input, 3 - a mix of the two. Enter a value for the maximum radius of a halftone dot, from 4 to 127 pixels. Choose Pixelate > Color Halftone from the Filter menu. The components in this device can be purchased for less than ten dollars and the code is simple enough for almost anyone to modify, making this a quick and inexpensive sound maker for performance or as a prank. Apply the Color Halftone filter In the Edit workspace, select an image, layer, or area.
By modifying an Arduino library developed by Conor Peterson for reading pixel data from the Agilent sensor to read movement and average darkness I was able to grab the data fast enough for a simple yet responsive standalone gestural synthesizer And the problem isnt just with adding two pixels, it affects antialiasing, blending. So, I decided to make a simplified version of the CCD synth using a mouse instead of the scanner. Even colour spaces are based on the completely arbitrary sRGB compression.
#PHOTOSOUNDER COLOR PIXEL SERIAL#
Recently I became aware that the sensors made by Agilent for optical computer mice do a lot of processing internally, both being able to provide a bitmap image (very slowly) and average darkness along with the change in X and Y using simple serial requests (much faster) rather than having to deal with a high-speed analog to digital conversion like the Scanman / Toshiba sensor. This became overly bulky, hardware-wise, and really didn't work as a standalone controller, so I put it on the back burner. In 2016, after being inspired by a video of the Scanman Line Follower on YouTube, I started work on a synthesizer device using the Toshiba TCD1304 linear CCD to synthesize audio from spectrogram data (or graphical data interpreted as spectrogram data) using Michel Rouzic's ARSS code (the source of his Photosounder application).
