Abstract: A solid-state imaging device in which a plurality of pixels are two-dimensionally arranged, the solid-state imaging device includes: a silicon layer; a plurality of photodiodes which are formed in the silicon layer to correspond to the pixels and generate signal charges by performing photoelectric conversion on incident light; and a plurality of color filters formed above the silicon layer to correspond to the plurality of the pixels, wherein a protrusion is formed in a region on a side of the silicon layer between adjacent ones of the color filters, the protrusion having a refractive index lower than refractive indices of the adjacent ones of the color filters and, each of the color filters is in contact with the adjacent ones of the color filters, above the protrusion.

Abstract: In a power detector, a comparator for detection receives an input signal and a reference voltage, and compares the input signal to the reference voltage around the switching time of active and inactive states of the output of the comparator in accordance with an output of an input switching signal generator. Except for the switching time, an input voltage for non-use of the comparator is inputs to the comparator for detection, and the differential inputs are fixed to the same potential. Therefore, aging reduction in the accuracy of power detection caused by BT degradation is effectively mitigated.

Abstract: An apparatus for recording and reproducing still pictures on and from a disk according to the invention comprises a still picture recording and reproducing means for recording a still picture in a particular position of a still picture recording region according to the last recording position information recorded in a recording position information sector specified by a pointer sector read out from the disk, and a still picture recording position information recording and reproducing means which, while managing a plurality of recording position information sectors so as to prevent the recording frequency of a recording position information sector from exceeding the maximum recording frequency, updates the recording position information about said still picture and the recording frequency of said recording position information sector and records them in the same or different recording position information sector, and which, when the recording position information is recorded in said different recording positio

Abstract: A travel route searching apparatus 1a includes at least a storage unit 11 and a processor 15. The storage unit 11 stores one or more pieces of travel point data including at least one travel point. The processor 15 selects one of the pieces of travel point data from the storage unit 11, and then obtains a start point and an end point that are required for a travel route search. Furthermore, the processor 15 obtains cartographic data of an area required for the travel route search, and then uses the obtained cartographic data to search for a travel route from the obtained start point via the travel point included in the selected travel point data selected to the obtained end point. Thus, it is possible to provide a travel route searching apparatus that requires only a small number of operations for designating travel points.

Abstract: With a time lapse recording/reproducing device for applying time lapse recording/reproducing processing to a video image signal gained through a video surveillance system and the like, a recording control unit (14) performs controlling by giving directions so that a signal obtained by applying picture compression processing to an inputted video signal in a picture compression/expansion circuit (11) provided with a means for intra, frame picture compression/expansion processing is recorded on rigid platters of a hard disk driver (12) as a moving picture and at the same time the foregoing signal is recorded intermittently on an optical disk of an optical disk driver (13), and, when an alarm signal is inputted, the foregoing signal is recorded on the rigid platters for a predetermined period of time as a moving picture and then has the recording operation ended, thus realizing a time lapse recording/reproducing device, whereby recorded moving pictures of the scenes just before and after the time when an alarm si

Abstract: A multiple channel multiplexing apparatus has a data compressor portion for producing compressed data, and a data expander portion for expanding the received compressed data. The data compressor portion has a data compression circuit for data compressing digital audio data and outputting the resulting data blocks, a sub-block divider for dividing the data blocks output from the data compression circuit into sub-blocks, a sub-block ID flag adding circuit for adding a sub-block identification flag identifying the sub-block arrangement, a multiplexer for generating sub-block groups by combining a plural channel group of sub-blocks with the added sub-block identification flags, and multiplexing the sub-block groups to the digital audio interface format.
