11 / 20 page µPD3719 11 DEFINITIONS OF CHARACTERISTIC ITEMS 1. Saturation voltage: Vsat Output signal voltage at which the response linearity is lost. 2. Saturation exposure: SE Product of intensity of illumination (IX) and storage time (s) when saturation of output voltage occurs. 3. Photo response non-uniformity: PRNU The output signal non-uniformity of all the valid pixels when the photosensitive surface is applied with the light of uniform illumination. This is calculated by the following formula. 4. Average dark signal: ADS Average output signal voltage of all the valid pixels at light shielding. This is calculated by the following formula. 5. Dark signal non-uniformity: DSNU Absolute maximum of the difference between ADS and voltage of the highest or lowest output pixel of all the valid pixels at light shielding. This is calculated by the following formula. ADS (mV) = dj : Dark signal of valid pixel number j 10600 Σ j=1 10600 dj dj : Dark signal of valid pixel number j DSNU (mV) : maximum of dj − ADS j = 1 to 10600 x Register Dark DC level VOUT ∆x ADS DSNU Register Dark DC level VOUT PRNU (%) = x = xj : Output voltage of valid pixel number j ∆x ∆x : maximum of xj − x x 10600 Σ j=1 10600 xj × 100 |
