MULTI-EYE IMAGE PICKUP APPARATUS AND ADJUSTING METHOD
First Claim
1. A multi-eye image pickup apparatus, including a first image pickup assembly having a first image sensor for photoelectric conversion of object light to generate a first image signal with plural color components, and at least one second image pickup assembly having a second image sensor for photoelectric conversion of said object light to generate a second image signal with plural color components, said multi-eye image pickup apparatus comprising:
- a memory for storing color calibration information defined in association with color sensitivity of said first and second image sensors for said plural color components;
a first corrector for adjusting said first image signal for respectively said plural color components, to correct a brightness level and white balance;
a second corrector for adjusting said second image signal for respectively said plural color components, to correct a brightness level and white balance;
a first gain setting unit for determining a first gain according to said first image signal, and for assigning said first corrector therewith; and
a second gain setting unit for determining a second gain according to said first gain and said color calibration information, and for assigning said second corrector therewith, to set equal said brightness level and said white balance between said first and second image signals.

Abstract
A stereoscopic camera includes a master camera for photoelectric conversion of object light to generate a first image signal with three color components G, R and B. A slave camera generates a second image signal. In an adjusting method, a first gain Dmr, Dmg and Dmb of the color components is determined according to the first image signal to correct a brightness level and white balance of the master camera, to adjust the first image signal by use thereof. A second gain Dsr, Dsg and Dsb of the color components is determined according to the first gain and color calibration information predetermined according to color sensitivity of the master and slave cameras in relation to the color components. The second image signal is adjusted by use thereof, for color matching between the first and second image signals to set equal the brightness level and the white balance.
