Vegetation change information properly indicating a time series change of a vegetation state can be generated. To this end, a data group including vegetation data of multiple time points respectively associated with ratio information which is a component ratio of ambient light is an object to be processed. This device includes an extraction section that extracts, from the data group, vegetation data for use by using ratio information, and a generation section that generates vegetation change information indicating a time series change of a vegetation state by using the vegetation data extracted by the extraction section. By use of ratio information, vegetation data obtained under similar ambient light conditions can be collected.

Method, product and blocking element of short wavelengths in LED-type light sources consisting of a substrate with a pigment distributed on its surface and, in that said pigment has an optical density such that it allows the selective absorption of short wavelengths between 380 nm and 500 nm in a range between 1 and 99%.

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

A multispectral sensor array can include a combination of ranging sensor channels (e.g., LIDAR sensor channels) and ambient-light sensor channels tuned to detect ambient light having a channel-specific property (e.g., color). The sensor channels can be arranged and spaced to provide multispectral images of a field of view in which the multispectral images from different sensors are inherently aligned with each other to define an array of multispectral image pixels. Various optical elements can be provided to facilitate imaging operations. Light ranging/imaging systems incorporating multispectral sensor arrays can operate in rotating and/or static modes.

A device comprises memory, a display characterized by a display characteristic, and processors coupled to the memory. The processors execute instructions causing the processors to receive data indicative of the display characteristic, data indicative of ambient lighting, and data indicative of content characteristics for a content item; determine a tone mapping curve for the content item based on the data indicative of content characteristics; determine a first, so-called “anchor” point along the tone mapping curve; modify a first portion of the tone mapping curve below the anchor point based on the data indicative of ambient lighting; modify a second portion of the tone mapping curve above the anchor point based on the data indicative of the display characteristic; perform tone mapping for the content item based on the modified toned mapping curve to obtain a tone mapped content item; and cause the display to display the tone mapped content item.

An integrated semiconductor optoelectronic component for sensing ambient light levels includes a silicon photomultiplier configured to deliver an output signal indicative of the intensity of the light that irradiates the component. The silicon photomultiplier has an active surface area for light detection. The component also includes an optical filter covering the active surface area of the silicon photomultiplier. The optical filter is adapted to selectively transmit light onto the active surface area as a function of wavelength. The optical filter is a scotopic filter and has a spectral transmission curve that mimics the spectral response of the human eye under low-light conditions. The component further includes readout electronics for processing the output signal of the silicon photomultiplier.

Methods and apparatus for using an indicator window of a handheld scanner as a trigger are disclosed herein. An example handheld scanner includes: a housing; an image sensor to capture image data through a front-facing opening; an indicia decoder; an indicator window positioned to face generally away from the front-facing opening and toward a user when the handheld scanner is in a handheld position; a light source disposed inside the housing to emit indication light through the window to provide an indication; a light detector disposed inside the housing and positioned to detect a reflection of the indication light received from an object positioned in front of or on the window outside the housing; and a processor configured to control a mode of the handheld scanner and/or a device in communication with the handheld scanner in response to the light detector detecting the reflection of the emitted indication light.

A method of improving performance of an averager is provided. The method includes steps of: (a) multiplying a value of a (n-1)th piece of output data by a value “N” to calculate a temporary value; (b) determining whether or not a difference between an nth piece of input data and the (n-1)th piece of output data is larger than or smaller than a zero value, if yes, compensating the temporary value to obtain a correction value and performing step(c), if no, setting the correction value and performing step(c); (c) dividing the correction value by the value “N” to obtain a first value; (d) subtracting the first value from the correction value and adding up the correction value and the nth piece of input data to obtain a second value; and (e) dividing the second value by the value “N” to calculate an output value of the averager.

One example provides a display device comprising a display panel, a touch sensor, an ambient light sensor, a processor, and storage. The storage comprises instructions executable by the processor to monitor an ambient light signal received from the ambient light sensor, detect, in combination with a call event, a threshold change in the ambient light signal that is indicative of the display device being proximate to a body of a user, and based at least on detecting the threshold change in the ambient light signal, modify an operation of the display device.
