An apparatus for color-dependent detection of image contents includes a light input coupling apparatus, carrier medium, measuring region, output coupling region, and camera apparatus. The light input coupling apparatus includes a light source to emit light at a first wavelength. The carrier medium receives the light and transmits the light by internal reflection to the measuring region. The measuring region includes a first diffraction structure that outputs light at the first wavelength. The first diffraction structure is formed as a multiplex diffraction structure to input light in a second wavelength range. The output coupling region includes a second diffraction structure formed as a multiplex diffraction structure that outputs light at the first wavelength and the second wavelength range. The camera apparatus captures light output from the carrier medium to the camera apparatus, and provides the light in a form of image data which correlates with the light.

An under-screen fingerprint sensing device and fingerprint sensing method are provided. The under-screen fingerprint sensing device includes a fingerprint sensor and a processor. The processor performs a first FFC on a first color original value, a second color original value, and a third color original value provided by the fingerprint sensor to determine whether a target object is a real finger. When the processor determines that the target object is an unreal finger, the processor performs a second FFC on the first color original value, the second color original value, and the third color original value to determine again whether the target object is the real finger.

An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.

A method and an apparatus for supporting a camera-based environment recognition by a means of transport using road wetness information from a first ultrasonic sensor. The method includes: recording a first signal representing an environment of the means of transport by the first ultrasonic sensor of the means of transport; recording a second signal representing the environment of the means of transport by a camera of the means of transport; obtaining road wetness information on the basis of the first signal; selecting a predefined set of parameters from a plurality of predefined sets of parameters as a function of the road wetness information; and performing an environment recognition on the basis of the second signal in conjunction with the predefined set of parameters.

A fingerprint recognition-based synchronous application starting method and device. By providing a sensing unit below a fingerprint recognition area of a display unit, when a user needs to start an application, the user only needs to synchronously click an icon corresponding to an application to be started in the fingerprint recognition area of the screen; the sensing unit acquires fingerprint information of the user, and then compares the acquired fingerprint information with preset fingerprint information, to start the application or perform unlocking. Compared with an existing approach for a mobile apparatus to start an application by means of fingerprint recognition, the method and device improves the operability of application icons on a screen and enhances user experience, and can also effectively reduce the overall thickness of a mobile apparatus, making the mobile apparatus thinner and lighter to meet the market demands.
