[0051] figure 1 The configuration of an image sensing device of this embodiment is shown. refer to figure 1 , reference numeral 1 designates a lens for forming an optical image of an object on the solid-state image sensing element 3 . Reference numeral 2 designates an aperture / shutter which has a shutter function and also serves as an aperture for controlling the amount of light passing through the lens 1 . Reference numeral 3 designates a solid-state image sensing element for capturing object light formed by the lens 1 and outputting an electrical signal. The solid-state image sensing element 3 has the Figure 20A with 20B The same structure as the solid-state image sensing element 13 shown in FIG. Reference numeral 4 designates a CDS unit for performing correlated double sampling operations to remove clocks and reduce noise in an electrical signal output from the solid-state image sensing element 3 . Reference numeral 5 designates a clamp circuit for switching a sign...

[0078] The following will refer to Figures 5 to 7 A second embodiment is described. Note that the basic configuration and operation of the image sensing device are the same as those referred to above figure 1 It is the same as that described in 2, so its description will be omitted. In addition, the solid-state image sensing element 3 has the same Figure 20A with 20B The same structure as shown in . Also, since the timing diagram is actually the same as the reference image 3 The content described is the same, the only difference is the OB level of the CDS output (see Image 6 ), so the use of image 3 A detailed description of the timing diagram.
[0079] Such as Figure 5 As shown in , in the image sensing device of the second embodiment, the clamp circuit 5 and the timing pulse generator 8 in the configuration of the image sensing device described in the first embodiment include Take the switches that change the clamp time constant within the phase, and these sw...

[0089] The following will refer to Figure 8 with 9 A third embodiment of the present invention is described. Note that the basic configuration and operation of the image sensing device are the same as those referred to above figure 1 It is the same as that described in 2, so its description will be omitted. In addition, the solid-state image sensing element 3 has the same Figure 20A with 20B The same structure as shown in . Also, since the timing diagram is actually the same as the reference image 3 The content described is the same, the only difference is the OB level of the CDS output, so the use of image 3 A detailed description of the timing diagram. Also, the timing diagram is actually the same as Image 6 in the same content, the only difference is the use of Image 6 described NMASK, so its description will be omitted.
[0090] Such as Figure 8 As shown in , in the image sensing device of the third embodiment, the timing pulse generator 8 in the configu...
