Image pickup apparatus

Claim 2

An image pickup apparatus comprising: an image pickup device for converting light into an electrical signal; a substrate voltage supply for selectively applying at least first and second substrate voltages to said image pickup device; a drive controller for controlling a first mode of driving said image pickup device with application of the first substrate voltage and for controlling a second mode of driving said image pickup device with application of the second substrate voltage; and a signal processing circuit which suppresses a difference between color reproducibility of a first image, based on an output signal of said image pickup device in said first mode, and color reproducibility of a second image based on the output signal in said second mode, which difference is caused by a difference in sensitivity between said first and second modes.

Claim 3

An image pickup apparatus according to claim 1 , wherein said signal process portion includes a white balance adjustment portion for adjusting the white balance of the signal from said image pickup device, and suppresses the difference between the color reproducibility of the first image and the color reproducibility of the second image by controlling said white balance adjustment portion.

Claim 4

An image pickup apparatus according to claim 2 , wherein said white balance adjustment portion includes a white balance detection portion for detecting a signal which is estimated to be white, from the signal output from said image pickup device and a white balance control portion for adjusting the signal from said image pickup device on the basis of a result of a detection by said white balance detection portion, and suppresses the difference between the color reproducibility of the first image and the color reproducibility of the second image by controlling said white balance detection portion.

Claim 5

An image pickup apparatus according to claim 1 , wherein said signal process portion includes a hue adjustment portion for adjusting the hue of the signal from said image pickup portion and suppresses the difference between the color reproducibility of the first image and the color reproducibility of the second image by controlling said hue adjustment portion.

Claim 6

An image pickup apparatus according to claim 1 , wherein the first mode is a mode for effecting the addition of signals of a plurality of pixels included in said image pickup apparatus to output a thus-added signal from said image pickup device, and the second mode is a mode for effecting the output of the signals from said image pickup device without adding the signals of the plurality of pixels.

Claim 7

An image pickup apparatus according to claim 1 , wherein the first mode is a mode for a moving image picking-up operation.

Claim 8

An image pickup apparatus comprising: an image pickup device provided with plural color filters; a substrate voltage supply for selectively applying at least first and second substrate voltages to said image pickup device; a drive controller which selectively controls a first mode of driving said image pickup device by applying the first substrate voltage and a second mode of driving said image pickup device by applying the second substrate voltage; and a signal processing circuit for processing a signal from said image pickup device; wherein said signal processing circuit includes a white balance adjustment portion, for adjusting the white balance of the signal from said image pickup device, wherein said white balance adjustment portion includes a white balance detection portion for detecting a signal which is estimated to be white, from the signal from said image pickup device, a white balance control portion for adjusting the signal from said image pickup device on the basis of a result of a detection by said white balance detection portion; and wherein said white balance detection portion effects different processings in the first and second modes, respectively.

Claim 9

An image pickup apparatus comprising: an image pickup device provided with plural color filters; a substrate voltage supply for selectively applying at least first and second substrate voltages to said image pickup device; a drive controller which selectively controls a first mode of driving said image pickup device by applying the first substrate voltage and a second mode of driving said image pickup device by applying the second substrate voltage; and a signal processing circuit for processing a signal from said image pickup device; wherein said signal processing circuit includes a white balance adjustment portion, for adjusting the white balance of the signal from said image pickup device, wherein said white balance adjustment portion includes a white balance detection portion for detecting a signal which is estimated to be white, from the signal from said image pickup device, a white balance control portion for adjusting the signal from said image pickup device on the basis of a result of a detection by said white balance detection portion; and wherein said white balance detection portion effects different processings in the first and second modes, respectively.

Claim 10

An image pickup apparatus according to claim 7 , wherein said white balance adjustment portion is arranged so that a white discrimination range of the detection of the signal which is estimated to be white differs between the first mode and the second mode.

Claim 11

An image pickup apparatus according to claim 7 , wherein the first mode is a mode for effecting the addition of signals of a plurality of pixels included in said image pickup apparatus to output a thus-added signal from said image pickup device, and the second mode is a mod for effecting the output of the signals from said image pickup device without adding the signals of the plurality of pixels.

Claim 12

An image pickup apparatus according to claim 7 , wherein the first mode is a mode for a moving image picking-up operation and the second mode is a mode for a still image picking-up operation.
