摘要:
A flip-up flash unit (5) for a camera (1) has a built-in viewfinder opening (37, 39) for viewing a subject to be photographed when the flash unit is swung to an operative position elevated from the body (3) of the camera. The body of the camera, therefore, can be made more compact because the need for a viewfinder opening in the body is eliminated.

A communication system comprises: a camera torch adapted to gather data, such as an image of a face, a fingerprint or a crime scene, and transmit the data to a receiving station, where the data may be stored in a secure memory. Means may also be provided at the receiving station to analyse, assess and compare the data with stored data and communicate the result to a remote operator, which may be the user of the torch camera, so as to provide an information about the person or object being imaged. The system is adapted to handle a range of data including human identification characteristics; such as fingerprints and iris patters.
摘要:
A finder apparatus which is used together with a photographing apparatus presents a marker for positioning (14a) for setting relative positions of the photographing apparatus and an object for calibration so as to be visually recognizable by an operator in a finder (12) configured to present an image of a subject so as to be visually recognizable by the operator, when photographing the object for calibration including at least one of a known shape and a known surface attribute in order to acquire parameters of a photographing optical system of the photographing apparatus.
摘要:
In a device for blending information into the finder beam path (S) of a motion picture camera having imaging optics (10, 11) and a DMD (digital micro-mirror device) chip (7) with a plurality of micro-mirrors arranged in a grid and swivelled by an electronic control, some of the micro-mirrors reflect the finder beam (S) towards the imaging optics (10, 11) while other micro-mirrors are at least temporarily swivelled out of the finder beam (S). Preferably, each of the micro-mirrors swivelled at least temporarily out of the finder beam (S) reflects a section of an information surface (9) towards the imaging optics (10, 11) of the finder.
摘要:
A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates controller parameters and. The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The convergence speed of the controller parameters is determined by a gain matrix that has non-diagonal and diagonal element. The system is configured that the controller parameters are determined without calculating the non-diagonal elements of the gain matrix, or without calculating using the non-diagonal elements of the gain matrix in the determination, decreasing calculation volume
