Datasheet
9. False pixel correction
The imager can have up to 1 defective pixel, 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 2C. The defective pixel result can be replaced by an interpolation of its neighboring pixels.
10. Detailed General Description
10.1. Pixel position The array consists of 192 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 12) and
j
is its column number (from 1 to 16) 6 5 4 3 2 1 0 1 1 1 1 1 1 1 l l l l l l l 9 8 7 6 5 4 3 2 1 l l l l l l l l l o o o o o o o o o o o o o o o o C C C C C C C C C C C C C C C C Row 1 Row 2 Row 3 Row 4 Row 5 Row 6 Row 7 Row 8 Row 9 Row 10 Row 11 Row 12 0 VDD GND SDA SCL Reference tab Figure 3 Pixel in the whole FOV REVISION 2 – FEBRUARY 6, 2019 [DOCSERVER NR] Page 9 of 53
