9. False pixel correction
The imager can have up to 4 defective pixels, with either no output or out of specification temperature reading.
These pixels are identified in the EEPROM table of the sensor and can be read out through the I

Pixel position
The array consists of 768 IR sensors (also called pixels). Each pixel is identified with its row and column position as
Pix(i,j) where i is its row number (from 1 to 24) and j is its column number (from 1 to 32)
