Abstract: In the application parallel processing system, on specific one of processors forming a multi-processor, an application is operated independently of other processors and on other processors, a function expansion module is operated in parallel processing under control of the application. As a result, even in such a data processing device internally provided with a processor whose processing capacity is small as a portable terminal, applications can be operated smoothly.

Abstract: The present invention relates to a parallel processing system by an OS for single processor capable of operating an OS for single processor and an existing application on a multiprocessor and achieving parallel processing by a multiprocessor with respect to the application, wherein the multiprocessor are logically divided into two groups, i.e., a first processor side and a second processor side, and units of work that are parallelizable within the application operating on the processors on the first processor side are controlled as new units of work on the processors on the second processor side.

Abstract: In a processor apparatus, at least one general purpose central processing unit loads object codes of requested newly-dispatched tasks to a memory. At least one specific signal processing unit core downloads the object codes of the newly-dispatched tasks from the memory to dynamically schedule generation and extinction of the newly-dispatched tasks and schedules operations of currently-executed tasks in accordance with instructions from the general purpose central processing unit.

Abstract: An edge correction apparatus for a digital video camera includes horizontal and vertical edge signal generators, horizontal and vertical edge signal gain controllers, an adder, a slice processor, and a vertical edge component suppression position detector. The horizontal and vertical edge signal generators respectively generate horizontal and vertical edge correction signals in the horizontal and vertical directions of a sensed image obtained via the image sensing element of a digital video camera. The horizontal and vertical edge signal gain controllers control the gains of the horizontal and vertical edge correction signals. The adder adds the horizontal and vertical edge correction signals whose gains are controlled. The slice processor adds, to the image processing signal of the digital video camera, an edge correction signal obtained by performing slice processing for an edge signal output from the adder.

Abstract: A digital still camera is equipped with, aside from a full frame type CCD, a sub CCD which can photograph a moving image, is small, and has less resolution and driving and process circuits thereof. The digital still camera permits preview image display on an image display device such as an LCD before main imaging. The output signal of the sub CCD is used to singly perform autofocus, white balance, photometry control, or dimmer control. A plurality of sensors corresponding to the respective functions must not be used, and the number of the driving circuits or control circuits can be reduced.
