摘要： In a solid state imaging device, signal charges are branched to be output to in the form of one or plural outputs. At a horizontal transfer speed not lower than a predetermined transfer speed, the imaging device transfers signal charges of color attributes classified by a branching section, to plural horizontal transfer paths, where the signal charges are converted into analog voltage signals, which will be output synchronously. At a horizontal transfer speed lower than the predetermined transfer speed, the analog voltage signal converted is output from, e.g. the horizontal transfer path which has been selected. Output amplifiers arranged on the horizontal transfer paths are differentiated in sensitivities in detecting signal charges, depending on color attributes of signal charges supplied, and output the analog voltage signals.

摘要： A CCD image sensor is driven in an interlace scan method, in which readout of signal charge is performed in two divided fields. In the first field, signal charge Qs accumulated in photodiodes of the first horizontal line and noise charge Qn generated in VCCDs on the second horizontal line are transferred. In the second field, the signal charge Qs accumulated in the photodiodes of the second horizontal line and the noise charge Qn generated in the VCCDs on the first horizontal line are transferred. The image signal based on the noise charge Qn obtained in the second field is subtracted from the image signal Qs based on the signal charge obtained in the first field. Then the image signal based on the noise charge Qn obtained in the first field is subtracted from the image signal based on the signal charge Qs obtained in the second field.

摘要： A solid-state image sensor prevents shading while maintaining the wider dynamic range of an image signal without reducing its optical resolution. The image sensor has plural pairs of higher- and lower-sensitivity photodiodes and micro-lenses each of which is provided over particular one of the higher- and lower-sensitivity photodiodes for collecting the light incident on corresponding one of the higher- and lower-sensitivity photodiodes. The micro-lenses provided over the lower-sensitivity photodiodes have the curvature thereof smaller than that of the other micro-lenses, thereby providing for the lower-sensitivity photodiode a significant amount of light even for a change of the exit pupil position or incident angle or the like that causes the position of an image circle to shift.

摘要： Pixel rows of an image sensor are respectively provided with a vertical transfer path. A charge detecting amplifier is disposed at one end of each of the vertical transfer paths. When a through image is outputted and when a moving-image mode is executed, a horizontal scanning circuit sequentially selects the charge detecting amplifiers on the basis of a thinning pattern, which is determined every imaging sensitivity, to output an image signal in which the pixel rows are thinned. As the thinning pattern, there are an odd-row pattern for selecting only the odd pixel rows from among the whole pixel rows, and an even-row pattern for selecting only the even pixel rows therefrom. The thinning pattern is selected in accordance with the imaging sensitivity so as to minimize line-shaped defects caused by the vertical transfer paths.

摘要： Each pixel has a main pixel and a sub pixel. Each pixel has a color filter. The color filters are respectively arranged above a main photosensitive portion of the main pixel and a sub photosensitive portion of the sub pixel. The thickness of the color filters above the main and sub photosensitive portions is different from each other, so that spectral sensitivity characteristics of the main and sub photosensitive portions are respectively different. In a WB gain determiner, the type of illumination light source is judged by comparing image signals taken out from the main and sub pixels. The WB gain determiner determines a gain correction coefficient based on the type of illumination light source. The gain correction in each RGB color is performed according to the gain correction coefficient to adjust the white balance.

摘要： A solid-state image sensor includes photodiodes, which constitute pixels, shifted in position from each other and red (R), green (G) and blue (B) filter segments fitted on the photodiodes in a preselected pattern. R transfer gates, G transfer gates and B transfer gates each are connected to a particular vertical transfer electrode. Particular vertical drive pulses are fed to the electrodes to drive the transfer R, G and B transfer gates. Photodiode read pulses are applied to each of the electrodes at a particular timing on the basis of image signals output from the image sensor. Consequently, a signal charge generated in each photodiode is shifted to a particular vertical transfer path via the R, G or B transfer gate in accordance with color-by-color exposure time.

摘要： A solid-state image sensor prevents shading while maintaining the wide dynamic range of an image signal without reducing its resolution. The image sensor has its photodiode array including arrangement patterns, each of which includes a smaller micro-lens and larger micro-lenses arranged on the top, bottom, right and left sides of the smaller micro-lens in a first virtual plane formed by the array. When the arrangement pattern is viewed in parallel to the virtual plane through a gap between the larger micro-lenses positioned on the bottom and left sides of the smaller micro-lens in the plane, the image of an unhidden part of the smaller micro-lens visible through the gap is, at most, half as much in area as the whole image of the smaller micro-lens projected on a second virtual plane perpendicular to the first virtual plane.
