摘要:
In an IC driver using SOI dielectric isolation structure having a lower and an upper arm side drivers, the upper arm side driver operates in a floating state, a carrier injector region is disposed in an semiconductor island where a switching device for the upper-side circuit is formed. The IC driver drives a set of an upper-side and a lower-side output power devices, a first main electrode of the upper-side output power device is connected to a high level power supply, a second main electrode of the upper-side output power device is connected to a first main electrode of the lower-side output power device, a second main electrode of the lower-side output power device is connected to ground potential (GND). The carrier injector region is formed deeper than a couple of main electrode regions of the switching device in the upper arm side driver. Moreover, this injector region is connected to an intermediate potential at connecting terminal of the upper-side and the lower-side output power devices. A current for compensating the displacement current Jd flowing in the parasitic condenser CSUB inherent to the SOI structure is supplied through the carrier injector from this intermediate potential terminal, to diminish the extra load of the internal power supply circuit for supplying the upper arm side driver with a predetermined voltage.

A lateral insulated gate bipolar transistor has an emitter region that is displaced from a main path for passing carriers from a collector region to a base region through a first semiconductor layer. This arrangement suppresses the operation of a parasitic transistor composed of the emitter region, base region, and first semiconductor layer and prevents a latch-up. The width of the gate electrode of covering the first semiconductor layer serving as a drift region of carriers may be widened to form a carrier accumulation layer in the first semiconductor layer adjacent to the gate electrode. The accumulation layer increases the total number of carriers in the drift region, to reduce a saturation voltage between the collector region and the emitter region. As a result, the lateral insulated gate bipolar transistor operates with a low voltage to reduce power consumption.

An information processing apparatus includes a storage unit, a display controller, an input receiver, a job management unit, and a sorting unit. The display controller performs control to display, on a display unit, a job list that is a list of one or more jobs and contains one or more setting items for each job. The input receiver receives selection of a setting item from the list. The job management unit stores, in the storage unit, arrangement orders of setting values of the setting items on the list when selection of the setting item is received. The sorting unit rearranges the jobs such that the setting values of the selected setting item are arranged in a predetermined order while keeping arrangement orders of the setting values of the setting items other than the selected setting item among the jobs in ascending or descending order as stored in the storage unit.

An image pickup apparatus includes an image pickup device including plural imaging planes each having different dark current characteristics, each of the imaging planes having an effective image area and an corresponding optical black (OPB) area. The image pickup apparatus also includes a memory that stores a dark current data table including difference data between dark current values pre-measured at upper and lower areas of the effective image area of each of the imaging planes and dark current values pre-measured at corresponding upper and lower areas of the OPB area. The image pickup apparatus further includes an image processing unit to calculate estimate dark current values for the effective image area based on the dark current data table and actual dark current values measured in the OPB area for each of the imaging planes, and eliminates the dark current components for the effective imaging areas.

An image capturing apparatus capable of removing a noise due to a dark signal from a solid-state imaging device is provided. After storing an image signal (A2) obtained through an ordinary capturing in an image memory, an image signal (B2) captured immediately thereafter with a shutter closed is stored in the image memory. Next, respective image signals (A2) and (B2) are supplied to a preprocessing circuit (6a) via a memory controller (6c). An arithmetic circuit (61), by subtracting the image signal (B2) from the image signal (A2), removes a fixed pattern noise and an offset component. A bright spot detection circuit (62) detects an occurrence position of a bright spot noise from the image signal (B2), and in response to this detection, outputs a timing pulse (T1). A black point compensation circuit (63), on the basis of the timing pulse (T1), detects a pixel having a possibility of occurrence of a black point noise, in an image signal (C1) outputted from the arithmetic circuit (61), and compensates for this pixel using a data of a pixel in the vicinity thereof.

For each pixel read from an imaging device, a horizontal counter value and a vertical counter value corresponding to the pixel are supplied from a signal generator to a distance computation section via an optical-axis-center coordinate setting section and an up-and-down and right-and-left weighting section. In the distance computation section, the distance to the optical-axis center is computed, and correction coefficients for the zoom wide end and for the zoom tele end, which correspond to the distance, are obtained by look-up tables. The two obtained correction coefficients are blended at a mixture ratio determined by a blend ratio setting section. The blended shading correction coefficients are gain adjusted by a gain adjustment section, after which they are supplied to a correction section. As a result, a correction corresponding to the distance to the optical-axis-center position is performed on the signal of each pixel supplied from an imaging section.
