Abstract: The invention relates to an optical device for aiming along an optical axis and visually indicating a reading area, comprising at least an illuminating assembling acting on a portion of the reading area along an optical emission path. The illuminating assembly comprises a light beam emitting source, a diaphragm having a preset shape, such diaphragm being effective to select a portion of the light beam generated by said emitting source, and a converging lens placed, on the optical emission path, downstream of the diaphragm and adapted to collimate the shaped light beam coming from the diaphragm and project it onto a portion of the reading area. The device of this invention is at once economical and accurate (i.e. capable of producing sharp images), thereby providing the user with a clear cut indication of the reading area being aimed regardless of the distance of the latter from the device.

Abstract: This invention relates to a process for regulating the exposure time of a light sensor, characterized in that it comprises the following steps: a) setting the exposure time of the sensor to a value selected in a first range of M prefixed values defined between a minimum and a maximum value; b) acquiring an image of an object on the sensor, such image comprising a plurality of luminous pixels; c) analyzing the acquired image in order to detect its level of luminosity; d) comparing the detected level of luminosity with a prefixed higher (lower) global threshold level representative of a condition of overexposure (under-exposure) of the image; e) varying the exposure time of the sensor and iteratively repeating the previous steps until an optimum exposure time equal to the highest (lowest) exposure time is found, amongst the ones set, for which the image presents a level of luminosity which is smaller (greater) than the prefixed higher (lower) global threshold level.
