FINGERPRINT SENSING DEVICE AND OPERATION METHOD THEREOF
A fingerprint sensing device and an operation method thereof are provided. The fingerprint sensing device includes a driver integrated chip and a fingerprint sensor. The driver integrated chip is coupled to a host processor. The fingerprint sensor is coupled to the driver integrated chip and the host processor. The fingerprint sensor obtains a fingerprint image during a period when the host processor is in the sleep mode. The driver integrated chip performs a fingerprint verification on the fingerprint image, and the driver integrated chip determines to wake up the host processor according to whether the fingerprint image passes the fingerprint verification.
License plate reading system with enhancements
System and methods are disclosed for capturing license plate (LP) information of a vehicle in relative motion to a camera device. In one example, the camera system detects the LP in multiple frames, then aligns and geometrically rectifies the image of the LP by scaling, warping, rotating, and/or performing other functions on the images. The camera system may optimize capturing of the LP information by executing a temporal noise filter on the aligned, geometrically rectified images to generate a composite image of the LP for optical character recognition. In some examples, the camera device may include an image sensor, such as a high dynamic range (HDR) sensor, modified to set long and short exposures of the HDR sensor to capture frames of a vehicle's LP, but without consolidating the images into a composite image. The camera system may set optimal exposure settings based on detected relative speed of the vehicle.
DIGITAL IMAGE GENERATION THROUGH AN ACTIVE LIGHTING SYSTEM
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an active lighting system. In one aspect, a method includes receiving a first image of the physical document having a first glare signature and a second image of the physical document having a second glare signature that is different from the first glare signature; determining a first glare map of the first image and a second glare map of the second image; comparing the first glare map to the second glare map; and generating the digital image based on the comparison of the first and second glare maps.
Color electronic rolling shutter image sensor for idenitfying items on fast moving conveyor belt
An image capture system has an electronic rolling shutter (ERS) imager in area mode with high illumination to perform image acquisition (i.e. barcode reading) for fast moving items. Shearing distortion may occur but image blur is reduced and the image can be decoded. The ERS imager replaces global shutter imagers at a much lower cost and wider availability. The image capture system separates illumination into multiple bands in space and then synchronize the illumination bands with the exposure of the ERS imager in time. Much less illumination is required for the same image quality.
Image processing system and method
The present disclosure provides an image processing system and method. The system includes an image capturing unit and an image processing unit. The image capturing unit includes a camera, a light source, and a wafer transfer stage. The camera captures an image of a wafer mark. The light source is capable of projecting through a plurality of chemical residues on the wafer mark. The image processing unit includes an image processor and an object matching subsystem. The image processor is configured to perform calculations of the image processing unit to generate an output result. The object matching subsystem includes an object matching unit and a memory unit. The object matching unit includes an artificial intelligence (AI) statistical model for identifying each character of the wafer mark. The memory unit stores a set of probabilities of the object matching unit detecting each character of the wafer mark in each image.
APPARATUS, SYSTEM AND METHOD FOR AUTHENTICATING IDENTIFICATION DOCUMENTS
A document scanner includes an enclosure with a scanning area. A transparent platform in the scanning area allows a user to position a document for authentication. A top camera takes a picture of the top of the document and a bottom camera takes a picture of the bottom under multiple light conditions including UV, IR, and white light. Mirrors reduce the enclosure size and multiple computers within the enclosure share work to process image data and determine document type. Types are searched in order based historically detected types. Barcode data is decoded and image samples are filtered as one of the computers finds a match. Security features are checked for the detected type and fake variants of the detected type are checked. Card information and formatting is validated and face data captured from a face camera and as shown on the document are matched against a database of banned users.

Method of taking a picture without glare
A glare reducing optical recognition system that recognizes alphanumeric text wherein the system includes a first light emitter that emits light in a first direction and a second light emitter that emits light in a second direction different from the first direction. The system includes an image capturing device that captures a first image of alphanumeric text illuminated by the first light emitter emitting light in the first direction, and a second image of the alphanumeric text illuminated by the second light emitter emitting light in the second direction. The system includes an image processor that constructs a glare reduced image by comparing sections of the first image with corresponding sections of the second image and selecting the section with the least luminosity to populate the corresponding section of the glare reduced image. The system may include a character recognition processor, a label producing apparatus, and/or a conveyance system.
Exterior lighting system for motor vehicle
This disclosure relates to an exterior lighting system for a motor vehicle. An example system includes a plurality of lights configured to illuminate an area adjacent the motor vehicle, a plurality of sensors, and a controller configured to selectively activate and deactivate the lights based on signals from the sensors. The example system includes various aspects configured to preserve energy, including reducing the polling rate of sensors corresponding to deactivated lights, increasing light intensity in proportion to the speed of detected motion, and only illuminating those lights that correspond to locations of a recognized user.
DIRECT PART MARKING CODE READING WITH MULTIMODAL OBJECT SENSING
An optical symbol reading system comprises an image sensor operative to capture an image of a target area, a color-sensing system sensitive to certain colors in the visible spectrum, an illumination system operative to produce various types of illumination based on illumination parameters, and a surface-profiling system arranged to measure distance to multiple points of at least one surface in the target area. The illumination system, the image sensor, and the color-sensing system are arranged such that emitted light from the illumination system, in accordance with a selected type of illumination, is directed towards the target area while a portion of the emitted light is reflected from any object of interest present in the target area and received by the image sensor and the color-sensing system. The type of illumination is selected based on output from the color-sensing system and the surface-profiling system.
