a u02dc 230 a and then the light sensing cells 231 a u02dc 235 a or some other arrangements for these three segments of light sensing cells obviously alternative arrangement such as illuminating the light sensing cells 221 a u02dc 235 a all at once and shifting the resulting potentials into the capacitor line 22 b in sequence is also possible however this will increase overall leakage of charges from the sensing cells 221 a u02dc 235 a and lead to a greater data distortion whether the cmos light sensor is illuminated once or in a multiple of exposures once a set of charges is produced inside the light sensing cells 221 a u02dc 235 a within the light sensing line 22 a the set of charges are converted into electric potentials and stored inside the capacitor line 22 b thereafter each potential inside the capacitor line is sequentially read to obtain the required image data 0028 fig3 5 are schematic diagrams showing the relationship between the light sensing lines and the capacitor lines in a staggered cmos light sensor according to this invention in fig3 and 4 only one of the three groups including the capacitor line that corresponds to.
