摘要： A driving method is applied to a solid-state imaging apparatus having photoelectric conversion portions, transfer portion for reading out signal charges, and an excess charge draining portion for draining charges exceeding a saturation charge amount that is set by a reference voltage. One of driving modes is selected from a full pixel mode in which accumulated signal charges are detected individually for each pixel and a pixel mixing mode in which signal charges of a predetermined number of pixels are mixed to be detected. In the full pixel mode, the draining portion is supplied with the reference voltage having the same value during a charge accumulation period and a read transfer period for read transferring charges. In the pixel mixing mode, the draining portion is supplied with the reference voltage having a low level during the charge accumulation period and the reference voltage having a high level during the read transfer period. An appropriate driving for the pixel mixing mode can be performed by avoiding a limitation of a substrate voltage, without deteriorating the spectral characteristics, the sensitivity, nor the linearity.

摘要： A drive unit 120 sets a saturation amount in a read period in which charges generated in pixels are read to vertical CCDs to be lower in a combination mode than in an individual mode (see Vsub in count values 22 to 24 in FIG. 6). As a result, excess charges in the pixels are drained to an n-type substrate 11. The drive unit 120 also sets an accumulation period to be shorter in combination mode than in individual mode (see Vsub in each mode in FIG. 6).

摘要翻译： 驱动单元120将组合模式中的像素中产生的电荷读取到垂直CCD的读取周期中的饱和量设置为比单独模式更低（参见图6中的计数值22至24中的Vsub）。 结果，像素中的过量电荷被排出到n型衬底11.驱动单元120还将组合模式中的累积周期设置为比单独模式更短（参见图6中的每个模式中的Vsub）。

摘要： A solid-state imaging device, and a camera provided with this device, that can output high quality images at high speed are realized by preventing improper OB clamping in a solid-state imaging device that performs pixel mixing in the horizontal direction. Vertical final stages, which are the transfer stages closest to a horizontal transfer component 4, are provided with provided with independent transfer electrodes V3-1, V3-2, V3-3, V6-1, V5-2, and V5-3 that are independent of other columns in a region between the horizontal transfer component and an effective pixel region, and a common transfer electrode that is common to all of the columns in the region between the horizontal transfer component 4 and the OB region. Further, in the vertical final stages, the entire region between the OB region and the horizontal transfer component, or the region minus openings formed for the wiring of V3-1 and V5-1 in the columns closest to the effective pixel region, is covered with a light blocking film.
