A video and audio data converter capable of insert-edit-processing another video data and audio data in real time while reproducing produced video and audio data and a disk apparatus using the video and audio data converter are configured so that a plurality of video and audio data input and output from a plurality of external apparatuses to video and audio input/output sections are input and output while the video and audio data input and output to one video and audio input/output section is replaced with the video and audio data input and output to another video and audio input/output section in a video and audio data conversion section.
摘要:
A data recording device, using a disc, wherein it is easy to handle respective audio signals independently and which receives digital data got by multiplexing plural audio signals is provided.In a data recording device according to the present invention data blocks are identified in the frame unit from among received digital data and, at least, the first audio block and the second audio block are generated from among the data blocks so that each audio block is recorded from the leading address of the recording segment formed on the disc.
摘要:
An data recording apparatus in accordance with the present invention is configured so as to determine whether a received data block is of the same data to a previously received data block or not on the basis of the data block particular information in the data block transmitted from the outside and stored in a buffer thereby determining the recording-or-not into a disk drive, or so as to determine whether it is to be recorded into the disk drive or not on the basis of the information transmitted from the outside.

A storage apparatus has input means for inputting an input/output execution time prediction request from an external system and determining means for predicting the execution time of the input/output request in response to the input/output execution time prediction request. The storage apparatus predicts the execution time of the input/output request and provides a response to the external system in response to the input/output execution time prediction request input from the external system.

The present invention is a magnetic disk apparatus which is provided with means for dividing a large amount of data such as video data into segments with error correction code added thereto and further dividing the data including the error correction code into recording segments, while being capable of efficiently correcting errors even for a sector size of large unit and processing sectors of variable length.
摘要:
An image encoding method is for obtaining, from a pixel data string containing pixel values of a plurality of pixels in a pixel array where the pixels are arrayed, a pixel data string containing a quantized representative value into which at least one of the pixel values is encoded. Encoding is performed by allocating a specific quantized representative value when a pixel value of a pixel is a specific pixel value, and by allocating a quantized representative value other than the specific quantized representative value when the pixel value is other than the specific pixel value.

The resolution, frame rate, or both can be improved when imaging moving subjects in an imaging apparatus using a CMOS image sensor. The imaging apparatus has an image sensor having a two-dimensional array of pixels. Each of the pixels includes an element operable to produce an electric charge by photoelectrically converting light from an imaged subject and a part operable to accumulate the produced charge and output an accumulated charge or a signal representing the accumulated charge. The imaging apparatus also has an area control unit operable to define a specified area of the image sensor containing a plurality of pixels and an area density control unit operable to specify a density of pixels read from the specified area defined by the area control unit.

Stereoscopic imaging device that can take stereo images with the parallax between the left and right eyes being accurately established is afforded. The stereoscopic imaging device (11) includes: an optical branching device having an incident surface (35), a beam-splitter part (33) that splits light from the incident surface into two directions, an extension part (36), and a reflection part (38) that reflects at least a portion of the light bent by the beam splitter part (33) and bends the reflected light in the y-axis positive direction; a first camera (31) that takes left-eye images; and a second camera (32) that takes right-eye images. The respective optical axes of the optical system of the first camera (31) and of the optical system of the second camera (32) are parallel to the y-axis.
