Patent ID: 7068314

Claim:
An image pickup apparatus comprising: an image pickup element having a color coding filter; a preprocessing circuit comprising (i) means for generating signals based on output from each line in the image pickup element and for outputting the same; (ii) spatial phase synchronization means for synchronizing horizontal and vertical spatial phases based on the output from each line in the image pickup element; and (iii) synthesis means for generating a synthesized signal based on a signal whose horizontal and vertical spatial phases are synchronized in the spatial phase synchronization means; a brightness processing circuit which receives the outputted signals from the means for generating signals and performs brightness processing thereon; and a chromatic processing circuit which receives the synthesized signal from the synthesis means and performs color processing thereon, wherein said outputted signals are delay signals sent to said preprocessing circuit containing a plurality of adders which compiles a sum of said delay signals and a ½ multiplier which halves the sum compiled from said plurality of adders, wherein said preprocessing circuit outputs said sum halved by said ½ multiplier to said brightness processing circuit, and wherein said preprocessing circuit sends said delay signals as the synthesized signal from the synthesis means to said chromatic processing circuit.
