摘要： A carrier level balancing circuit in which a color aliasing signal occurring when a cameraman takes a picture of an object of an achromatic (black and white) color can be canceled completely. In a carrier level balancing circuit for a color camera formed of a CCD solid state image pickup device of an all pixel separately read out system, two-channel color signals output from the CCD solid state image pickup device are multiplied with independent balance coefficients at every line by multipliers while the balance coefficients are switched in a dot-sequential fashion. Also, values of these balance coefficients are set by a coefficient setting circuit in response to color temperature information. Thus, the carrier levels can be balanced over a range of color temperatures.

摘要： A dynamic range is widened by effectively using an output range that is originally possessed by a solid-state image-capturing device, and an image having less color hue rotation is obtained.By using the fact that the margin until the amount of saturation electric charge is reached becomes large as a result of the amount of exposure being set to be low in a high sensitivity mode, an RGB signal having a wide dynamic range containing signal components of a subject on the high-luminance side is obtained. First, γ correction close to a power γ is performed and thereafter, the signal is color-space-converted into a luminance signal and color-difference signals. A non-linear compression process is performed on the luminance signal so as to be fit into predetermined gradations, and for the color-difference signals, color rotation is reduced using a power gamma and color-difference matrix clipping is performed.

摘要： A solid-state image pickup apparatus of the type from which signal charge can be read out for two lines at a time, wherein the amount of smear is made equal at locations above and below a point light source on a screen and a correcting circuit for such smear amount can be constructed in a simplified structure. In the solid-state image pickup apparatus, in a first field, a vertical transferring section is driven, immediately after signal charge has been read out from light sensitive sections, to transfer the signal charge by a two stage distance. But in a second field, immediately before reading of signal charge from the light sensitive sections, the vertical transferring section is driven to effect transfer by a one stage distance and then driven, immediately after such reading of signal charge, to effect transfer by another one stage distance, whereafter it is driven to effect transfer by a two stage distance upon each transferring operation.
