Patent ID: 7817198

Claim:
An active pixel array of a CMOS image sensor comprising: a pixel sensor array that includes a first pixel sensor configured to detect first and second light signals, of which the wavelengths are different from each other, among all wavelengths of light signals so as to generate current and voltage signals; and a second pixel sensor configured to detect a third light signal with a predetermined wavelength so as to generate a current or voltage signal are alternately arranged; and a color filter array that is formed on the pixel sensor array and in which a filter which transmits all wavelengths of light signals and a filter which transmits the third signal with a predetermined wavelength are alternately arranged; wherein the color filter array is formed by repeatedly arranging a basic unit composed of first and third filters which transmit all the wavelengths of light signals and second and fourth filters which transmit the third light signal; wherein: the first pixel sensor comprises a first photoelectric conversion section, which detects the first and second light signals so as to generate a current signal, and first and second active pixel circuits which convert the generated current signal into a voltage signal to output; the second pixel sensor comprises a second photoelectric conversion section, which detects the third signal so as to generate a current signal, and a third active pixel circuit configured to convert the generated current signal into a voltage signal to output; a third pixel sensor that includes a third photoelectric conversion section configured to detect the first and second light signals so as to generate a current signal, and fourth and fifth active pixel circuits configured to convert the generated current signal into a voltage signal to output; and a fourth pixel sensor that includes a fourth photoelectric conversion section configured to detect the third light signal so as to generate a current signal, and a sixth active pixel circuit configured to convert the generated current signal into a voltage signal to output, and wherein the pixel sensor array is formed by repeatedly arranging a basic unit composed of the first to fourth pixel sensors.
