A system for presenting information to passengers in a conveyance, has a computer which stores operation diagram information; a storage medium which stores a plurality of advertisement data items to be presented to the passengers; and an information presenting device. The computer obtains an operation time in each operation section on the basis of the operation diagram information and identification data for identifying the conveyance, and selects and arranges some of the advertisement data items to generate presentation data for continuously presenting information to the passengers throughout a time period corresponding to the operation time. The information presenting device reproduces the presentation data corresponding to each operation section to present the information to the passengers in each operation section of the conveyance.

A semiconductor laser controller comprising an optical detecting circuit for detecting the output of a semiconductor laser, a first circuit for controlling the semiconductor laser driving current on the basis of a bottom output of the semiconductor laser detected by the optical detecting circuit, a detecting and holding circuit which detects the peak output at the start of the pulse modulation of the semiconductor laser and holds the peak output, and a second means for the feed-forward control of the modulated pulse amplitude of the semiconductor laser after the start of the pulse modulation, whereby the semiconductor laser controller is capable of restricting the change of the peak output of a semiconductor laser resulting from the variation of the quantization efficiency with temperature and passage of time, and stabilizing the peak output within a short time.

Image feature values Va and Vb are derived from image data, coefficients C and D are determined based on the image feature values Va and Vb, and an approximate expression expressed with the file size Sfj of the JPEG compression file and the quantization data coefficient value Aqt is derived. Next, by designating the file size of a desired predetermined JPEG compression file based on the approximate expression, the quantization data coefficient value Aqt is derived, and a first quantization table as a reference is multiplied by the quantization data coefficient value Aqt, whereby a second quantization table is obtained. Then, using the second quantization table, the image data is actually JPEG-compressed.

An information recording and retrieval system, such as an optical system, for recording and reading signals, such as video signals and audio signals, on a recording medium provides improvement in the control of a moving part, such as an objective lens. In a first embodiment, reading of code signals is detected to disable the control of the moving part by the recorded code signals, recorded as discontinuities in a recording track, and to enable control by information signals, recorded as changes in reflectivity in the track, held by a holding circuit so that only recorded information signals operate the control to avoid control distrubances caused by differences in the recorded code and information signals. In another embodiment peak detecting circuits detect the minimum values of split detection signals for controlling the moving part; use of these minimum values for control avoids the control disturbances from the differences in signal reading during recording and reading modes.

An apparatus has not been configured without accompanying entirely changing and revising the system LSI when the specification of the apparatus or the system LSI configuring the apparatus is changed, and also, development cost has not been able to be reduced and development period has not been able to be shortened. An image information apparatus is realized in which new functions are easy to be added into the image information apparatus without need for development of a new system LSI for each model, by installing into the image information apparatus a ubiquitous image module having configurational elements such as a hardware engine, CPU, and general-purpose bus for realizing functions that have not been provided on the image information apparatus itself, and also including an OS for operating the configurational elements.
摘要:
An image equipment (40) includes an LSI (208) to control itself, and an interface (31) to connect with a ubiquitous image module unit (42) including a ubiquitous image module (12). The ubiquitous image module (12) included in the ubiquitous image module unit (42) connected to the image equipment (40) controls the LSI (208) included in the image equipment (40), so that it becomes possible to realize a new function which the image equipment (40) itself has not had. By this, it becomes unnecessary to develop a new LSI for expanding a function.
