## Abstract

A writing utensil including a color sensor operable to generate sensor data A processing unit is configured to receive the sensor data from the color sensor and to output the sensor data. A networking device is configured to receive the sensor data from the processing unit and arranged to transmit the sensor data via a network connection.

## Claims

### Claim 1

A writing utensil, comprising:
a color sensor operable to generate sensor data,
a processing unit configured to receive the sensor data from the color sensor and to output the sensor data, and
a networking device configured to receive the sensor data from the processing unit and arranged to transmit the sensor data via a network connection, and
a switch, wherein the writing utensil is operable to:
generate the sensor data initiated by user interaction by activating the switch,
transmit the sensor data via the networking device to a receiver by activating the switch again, and
trigger taking an image by means of the imaging device by activating the switch again.

### Claim 2 (depends on 1)

The writing utensil according to claim 1, wherein the color sensor comprises:
a multispectral sensor, and/or
an ambient light sensor.

### Claim 3 (depends on 1)

The writing utensil according to claim 1, wherein the processing unit is configured to determine a light condition based on a comparison of predefined spectral data to sensor data corresponding to an output of the color sensor.

### Claim 4 (depends on 3)

The writing utensil according to claim 3, wherein the light condition involves:
an ambient light source classification for adjusting a color balance,
a correlated color temperature, CCT,
a color rendering index, CRI,
a type of light source, and/or
an output of a multi-color light source such as a LED.

### Claim 5 (depends on 1)

The writing utensil according to claim 1, wherein:
the writing utensil comprises a handheld housing and
the color sensor is arranged at an end section of the handheld housing.

### Claim 6 (depends on 5)

The writing utensil according to claim 5, wherein
the end section comprises a cavity, and
the color sensor is arranged in the cavity.

### Claim 7 (depends on 5)

The writing utensil according to claim 5, wherein
a push button is connected to the end section, and
the color sensor is arranged in a cavity of the end section or in a cavity of the push button.

### Claim 8

(canceled)

### Claim 9

A light detection system, comprising:
a writing utensil, and
an imaging device comprising a receiver operable to receive sensor data to be transmitted by the networking device, wherein the writing utensil comprises:
