【Sensor IC spectral sensitivity】
This product comprises a color trilinear sensor ICs that
feature Filter-on-Chip technology. The Sensor IC's spectral
sensitivity is described on the left.
【Pixel alignment of Sensor ICs】
The plural Sensor ICs are assembled in a line on a sensor
board in this product. The numbers of 288 pixels x 3 color
Sensor ICs for each length are as follows;
1064 mm size : 87 chips
1247 mm size : 102 chips
1688 mm size : 138chips
Because keeping enough dicing area at the edge of Sensor
ICs is necessary, the resolution between the neighboring
pixels of neighboring Sensor ICs is not 600 dpi, and is
designated to be 300 dpi (84μm) pitch and controlled to be
placed within 1/3 pixels(±15μm) tolerance.
Therefore, the pixel pitch between the neighboring sensor
ICs is arranged in 300dpi pitch, and doesn't output a pixel
data between sensor ICs, which is called "missing pixel".
Additionally, a function of Interpolation that can insert a
pixel data created by neighboring pixels data for each gap
between neighboring Sensor ICs is available on this
product.
