Semiconductor device and electronic device

A semiconductor device comprising:

• an image processing portion comprising a first functional circuit and a second functional circuit and electrically connected to a source driver;
• a first scan chain electrically connected to the first functional circuit;
• a second scan chain electrically connected to the second functional circuit;
• a controller electrically connected to the first scan chain and the second scan chain;
• a first selector between the first scan chain and the controller;
• a second selector between the second scan chain and the controller;
• an input terminal;
• a first transistor between the first scan chain and the controller;
• and
• a second transistor between the second scan chain and the controller,
• wherein a channel formation region of each of the first transistor and the second transistor comprises an oxide semiconductor, and
• wherein the controller is configured to supply control data to the first selector and the second selector where data supplied from the input terminal does not pass through the first scan chain and pass the second scan chain,
• wherein the data that passes through the second scan chain supplies to the second functional circuit where a parameter stored in the second functional circuit is rewritten, and
• wherein the second functional circuit is configured to correct image data using the parameter and supply the corrected image data to the source driver.
