A methodology for dynamic (i.e., run-time) uploading and execution of applications and drivers between devices (e.g., between “client” device and one or more (host) devices), in a fully automated manner, is described. The device which is to be hosted (e.g., the “client” device) initially probes its environment to determine which device or devices it is attached to (e.g., the “host” device(s)). Once it has correctly discerned the relevant host or target device(s), the client device includes the capability of immediately sending out (i.e., uploading) a particular driver or application (i.e., object or file of interest) for placement, and ultimately execution, at the host device. Once the particular object or file of interest has been “injected” into the host device and is executing, the client device may simply revert to a “listening mode” in which it waits to be told what to do (i.e., receive commands from the application or driver which is now executing at the host device). This approach is particularly well-suited for devices which serve as “add-on” devices (clients) to other devices (hosts) that are “smarter,” for instance, including more processing capability and/or memory. In this scenario, the client device enters into a dialog with a device with more resources for the purpose of harnessing the resources of the host device for operating the client or add-on device. The client device is, using this approach, able to start running (i.e., driver-directed operation) immediately upon attachment to a host device that can be identified.

Camera with light emitting function
For flash photography, a rise of a flash emission control pulse precedes emission timing by a predetermined period. A start of flash emission of a flash lamp precedes a start of exposure of an image sensor. Since the start of the emission is earlier than the start of the exposure, a period of unstable flash emission can be excluded from an exposure time T of the image sensor. The exclusion prevents a captured image from being affected by the period of unstable flash emission. Accordingly, it becomes possible to ensure high color reproducibility for photography with auxiliary light.

In an embodiment, a sampling signal to each data signal line is generated by using an output signal outputted from each flip-flop, and a precharge signal by which the data signal line to which the sampling signal is to be outputted is precharged is generated by using an output signal outputted from an output terminal of the flip-flop. Further, by providing a NOR circuit, an active period of the precharge signal and an active period of the sampling signal are prevented from overlapping each other. With this, in an embodiment of a display device driving circuit, including a precharge circuit, which causes a precharge power supply to precharge signal supply lines, the number of shift registers and the size of a circuit can be reduced.
Driver circuit for display device and display device
A driver circuit for a display device includes NOR circuits on the input side of switches for controlling precharge of data signal lines and selected pixels connected to the data signal lines. While a video signal is written onto a data signal line, a signal instructing precharge of another data signal line is inputted from a shift register to the NOR circuits. A simultaneous precharge instruction signal is inputted from outside to the NOR circuits. According to this arrangement, precharge is performed in both a period in which a video signal is supplied to a data signal line and a period in which no video signal is supplied to any of the data signal lines. As a result, it is possible to perform precharge even with a precharge power source having relatively low driving capability, and to precharge the signal supply lines of the display device sufficiently.
