摘要： This invention provides an integrated time-of-flight sensor that delivers distance information to a processor associated with the camera assembly and vison system. The distance is processed with the above-described feedback control, to auto-focus the camera assembly's variable lens during runtime operation based on the particular size/shape object(s) within the field of view. The shortest measured distance is used to set the focus distance of the lens. To correct for calibration or drift errors, a further image-based focus optimization can occur around the measured distance and/or based on the measured temperature. The distance information generated by the time-of-flight sensor can be employed to perform other functions. Other functions include self-triggering of image acquisition, object size dimensioning, detection and analysis of object defects and/or gap detection between objects in the field of view and software-controlled range detection to prevent unintentional reading of (e.g.) IDs on objects outside a defined range (presentation mode).

摘要： A processor measures a first distance to an object in a distance measurement target region on the basis of an irradiation timing when a light irradiator performs surface irradiation on the distance measurement target region with light and a light receiving timing when a light receiver receives reflected light of the light from distance measurement target region. In a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation by the light irradiator, the processor measures the first distance on the basis of a relationship between the plurality of signals.

摘要： Aspects of the present disclosure are directed to a method for focusing a camera. In one embodiment, the method includes: dividing the field of view of the camera in to at least two segments: assigning, in each case, at least one operating element or at least one position of an operating element to the at least two segments; recognizing and tracking at least one object in at least two segments; automatically assigning the recognized at least two objects to the respective operating element or position of the operating element depending on which segment the objects are assigned to; and focusing the camera on the object assigned to the operating element or the position of the operating element in response to the operating element being actuated or the operating element being brought into the corresponding position.

摘要： The invention relates to an autofocusing method for an imaging device (for semiconductor lithography) comprising an imaging optical unit, an object to be measured and an autofocusing device having a reflective illumination, comprising the following method steps:



a) defining at least three basis measurement points M(xj, yj) on a surface of the object,
b) determining the deviation Az(M)j of a nominal position of the surface of the object from the focal plane of the autofocusing device at the defined basis measurement points M(xj, yj),
c) storing the deviations Az(M)j from at least three basis measurement points M(xj, yj),
d) using the stored deviation Az(M)j for determining a deviation Az(P)k at an arbitrary point P(xk, Yk) of the surface, and
e) using the deviation Az(P)k for focusing onto the point P(xk, Yk).

摘要： Hand-held devices combine smartphones and electronic binoculars. In “in-phone” embodiments, binocular functionality is integrated directly into the housing or body of a smartphone modified in accordance with the invention, whereas, in “in-case” embodiments, the binoculars are integrated into a case to receive a smartphone which may be of conventional design. In either case, components within the phone may be used for image manipulation, image storage, and/or sending and receiving/streaming stereoscopic/3D motion imagery. The objective lenses for the binoculars are preferably supported on or in one of the longer side edges of the phone or case, whereas the display magnifying eyepieces are preferably associated with the opposing longer side edge of the phone or case. As such, in use, a user holds the phone or case in a generally horizontal plane during use as binoculars.
