摘要:
L'invention concerne un procédé de calibration d'un système de visée comprenant un viseur et une optique de détection de la position d'un objet dans l'espace, caractérisé en ce qu'il comprend la détermination d'une loi de commande à appliquer au viseur pour viser l'objet en fonction de sa position, ladite position étant déterminée dans un référentiel de l'optique de détection et la loi de commande comprenant deux commandes angulaires et une commande de mise au point du viseur, exprimées en fonction des positions relatives entre l'objet à viser et un point concourant de toutes les lignes de visée du viseur, le procédé comprenant les étapes consistant à : - viser (100), avec le viseur des objets se trouvant à au moins six positions différentes connues dans le référentiel du système de visée et relever les commandes correspondantes, - à partir des positions de l'objet et des commandes correspondantes, déterminer (200, 200') la position du point concourant des lignes de visées et la loi de commande par la minimisation d'une fonction de la dérivée seconde de la loi de commande.
摘要:
An adjusting assembly for a lens of a camera has a hollow housing (1) with a mounting portion (11), at least one driving ring (40) mounted around the lens, at least one turning rod (30) mounted through the mounting portion (11) and engaging with the at least one driving ring (40), and at least one limiting ring (33) embedded in the mounting portion (11) of the housing (1). The mounting portion (11) is integrally formed on the housing (1) and has an enlarged thickness that allows the at least one turning rod (30) to be stably mounted on the housing (1). The at least one turning rod (30) is embedded in the housing (1), such that appearance of the housing (1) is smooth and pleasing.

A method of blurring an image includes acquiring two images of nominally a same scene taken at a different light exposure levels. At least one region of one of the images includes pixels having saturated intensity values. For at least one of the saturated pixels, values are extrapolated from the other image. At least a portion of a third image is blurred and re-scaled including pixels having the extrapolated values.

Disclosed are an electronic device and a method of controlling the same. An electronic device includes: a camera; a sensor module; and a processor, wherein the processor is configured to determine at least one of a movement of the electronic device and a movement of an object in images acquired by the camera, determine, based on the movement of the electronic device or the movement of the object, an output period for light outputted by the sensor module, and determine depth information of the images based on reflected light corresponding to the outputted light received by the camera.
摘要:
An optical device (1) including a fixed focus camera having a predetermined depth of field with an optical axis (55), wherein the optical device (1) comprises a diaphragm (5) positioned in the optical axis (55) of the camera and comprising a light passing aperture (53) for increasing the predetermined depth of field of said camera to provide an increased depth of field, wherein the light passing aperture (53) of the diaphragm (5) is circular shaped and positioned to have its centre point coincide with the optical axis (55) of the camera and wherein the optical device (1) further comprises illumination means for evenly illuminating an object positioned within the increased depth of field of the camera.
摘要:
A camera to which a lens unit is exchangeably attached includes a phase difference detection type focus detection unit, a contrast detection type focus detection unit, and a processor configured to acquire correction information used to correct a shift amount between a focus detecting light flux and an image-pickup light flux from the image pickup lens. The contrast detection type focus detection unit performs scanning in a single direction from a focus position detected by the phase difference detection type focus detection unit, the single direction being set based on the correction information.
摘要:
An autofocus system which can prevent erroneous tracking of an unintended tracking target, is provided. In a recognition and tracking mode which uses an AF frame to automatically track a face of a specific person for which certification data is previously stored, a face of a specific person designated by an operator is detected by face authentication processing from a captured image obtained from a television camera . Thereafter, the face is detected from the captured image by a pattern matching processing in which an image of the face is used as a reference pattern for object tracking processing, and the AF frame is moved to the detected position. The face recognition processing is executed each time when the object tracking processing is executed a predetermined times, thereby preventing erroneous tracking by the object tracking processing.
