first embodiment
[0096]
[0097]FIG. 2 is a diagram showing an example of the pixel arrangement regarding the color filters mounted to a light reception section of the image pickup device according to a first embodiment of the present technique. The pixel arrangement shown in FIG. 2 is basically the same as that shown in FIG. 1 except that pixels having different sensitivities are arranged.
[0098]In FIG. 2, the rectangles that are not hatched inside represent long exposure pixels, and rectangles that are hatched inside represent short exposure pixels. Moreover, indicated inside each rectangle are a symbol indicating the type of color filter and a symbol indicating either a long exposure or a short exposure.
[0099]For example, “GL” is assigned to the long exposure pixels out of the G pixels to be described as GL pixels, and “GS” is assigned to the short exposure pixels to be described as GS pixels. Similarly, “RL” is assigned to the long exposure pixels out of the R pixels to be described as RL pixels, an...
second embodiment
[0204]In a second embodiment of the present technique, a circuit structure onto which one A / D converter shared by two pixels in the horizontal direction is mounted will be described. It should be noted that in the descriptions below, descriptions on parts that are in common with the image pickup device according to the first embodiment will partially be omitted.
[0205]
[0206]FIG. 13 is a diagram showing a structural example of a pixel control circuit and pixel wirings in an image pickup device according to the second embodiment of the present technique. The image pickup device includes a vertical scan control circuit (V Scan Circuit) 81, a horizontal transfer circuit (H Transfer Circuit) 82, column switches (SW) 101 provided every two rows, A / D converters (ADC) 83 provided every two rows, memories (MEM) 84 provided every two rows, and the plurality of pixels 20.
[0207]It should be noted that parts that are the same as those of the structural example of the pixel control circuit and pix...
third embodiment
[0229]In a third embodiment of the present technique, a circuit structure in which 4 pixels in the vertical direction share a single FD (Floating Diffusion) will be described. It should be noted that in the following, descriptions on the parts that are common with the image pickup device of the first embodiment will partially be omitted.
[0230]
[0231]FIG. 15 is a diagram showing a structural example of a basic circuit of pixels included in an image pickup device according to the third embodiment of the present technique. FIG. 15 shows a vertical direction 4-pixel sharing pixel circuit in which 4 pixels consecutively arranged in the vertical direction are connected to a single FD 72 via pixel transfer transistors 73-11 to 73-14 and share the circuit structure CMN 131 subsequent to the FD 72.
[0232]The pixels are connected to the pixel transfer control signal lines TRG 21 to 24, the pixel readout selection control signal line SEL 75, the vertical signal line (readout line) VSL 76, and th...
