A color image pickup apparatus includes a photo-to-electric conversion section subjected to progressive scanning. A first delay circuit defers an output signal of the photo-to-electric conversion section. A first adder combines the output signal of the photo-to-electric conversion section and an output signal of the first delay circuit. A second delay circuit defers the output signal of the first delay circuit. A second adder combines the output signal of the photo-to-electric conversion section and an output signal of the second delay circuit. A third delay circuit defers an output signal of the first adder. A first subtracter implements subtraction between the output signal of the first adder and an output signal of the third delay circuit. A fourth delay circuit defers an output signal of the second adder. A second subtracter implements subtraction between the output signal of the second adder and an output signal of the fourth delay circuit. A first sign change circuit inverts a sign of an output signal of the first subtracter. A first selector periodically and alternately selects one of the output signal of the first subtracter and an output signal of the first sign change circuit. A second sign change circuit inverts a sign of an output signal of the second subtracter. A second selector periodically and alternately selects one of the output signal of the second subtracter and an output signal of the second sign change circuit. Two different color-difference signals are generated in response to an output signal of the first selector and an output signal of the second selector.

An image sensor includes a color filter array including a primary color pixel such as a green filter pixel for sensing a predetermined primary color, a first secondary color pixel such as a yellow filter pixel, and a second secondary color pixel such as a cyan filter pixel. The primary color pixel, the first secondary color pixel, and the second secondary color pixel form different area ratios in the color filter array. For example, the area ratio of the yellow filter pixel to the cyan filter pixel and the green filter pixel is 2:1:1 in the color filter array. In addition, the color filters of the pixels are compensated for crosstalk effect. Such an image sensor has enhanced color reproducibility and sensitivity.

A method and an apparatus for estimating behaviors of a vehicle are provided. At least two GPS antennas are located along a longitudinal axis of a vehicle so that speed vectors at the positions where the GPS antennas are located can be determined based on GPS signals received by the GPS antennas. The speed vectors are known to be estimated with high accuracy based on the GPS signals. The positions of the GPS antennas on the local coordinate system are estimated based on such highly accurate speed vectors, so that the estimated positions may also have high accuracy. Based on a line connecting these highly accurate positions of the GPS antennas, an inclination of the longitudinal axis of the vehicle is estimated. Use of the high-accuracy speed vectors enables high-accuracy estimation on the positions of the GPS antennas and the vehicle direction on the local coordinate system.
