20120241592 | Sensing pixel structure for generating sensed image with uniform resolution and light sensor - A sensing pixel structure for generating a sensed image with uniform resolution is applied in a light sensor. The sensing pixel structure includes a plurality of first sensing pixels and a plurality of second sensing pixels. The location of the plurality of first sensing pixels corresponds to a center region of a lens. Each of the plurality of first sensing pixels has a first pixel area. The location of the plurality of second sensing pixels corresponds to the peripheral region of the lens. Each of the plurality of second sensing pixels has a second pixel area. The first pixel area is larger than the second pixel area, so that number of the sensing pixels corresponding to the peripheral region of the lens is larger than that corresponding to the center region of the lens. Therefore, the light sensor generates the sensed image with uniform resolution. | 09-27-2012 |
20130100081 | OPTICAL TOUCH DEVICE AND PORTABLE ELECTRONIC DEVICE WITH HEART RATE MEASURING FUNCTION AND METHOD FOR INCREASING ACCURACY OF HEART RATE MEASUREMENT - Method for increasing accuracy of heart rate measuring includes sensing a finger of a user for generating sensed images of the finger, obtaining displacement information of the finger according to the sensed images, then using the motion information to compensate the sensed images of the finger, and finally using brightness variation of the compensated sensed images of the finger to measure heart rate of the user. | 04-25-2013 |
20130120114 | BIOFEEDBACK CONTROL SYSTEM AND METHOD FOR HUMAN-MACHINE INTERFACE - A biofeedback control system and method includes monitoring a physiological condition of a user to generate a sensing signal including a physiological information of the user, extracting a physiological variation information from the physiological information to generate a biofeedback signal, and generating a control signal based on the physiological variation information for controlling scenes, scenarios, background music or audio-visual effects of a program or a game. By this way, the biofeedback control system and method can trace a user's mood to automatically adjust a video output or an audio output of an electronic system where a program is playing or a game is running to enhance amusement. | 05-16-2013 |
20130129164 | IDENTITY RECOGNITION SYSTEM AND METHOD BASED ON HYBRID BIOMETRICS - An identity recognition system and method capture an image of a subject that is projected by light of different wavelengths, extract various biometric informations from the image, analyze and compare for each of the biometric informations to generate a matching score, and determine an identity for the subject according to all of the matching scores. The system and method have higher recognition accuracy, lower false acceptance rate, lower false rejection rate, and higher flexibility. | 05-23-2013 |
20130194236 | OPTICAL INPUT DEVICE AND INPUT DETECTION THEREOF - An optical input device integrates functions of fingerprint recognition, movement detection, and physiological analysis, and has a touch surface for receiving touch input of a finger. When a finger contacts the touch surface, the optical input device captures images from the touch surface, detects movement of the finger to generate a movement signal, extracts a fingerprint feature and a vessel blood changing feature from the images, analyzes and compares the fingerprint feature for identity recognition, and performs calculation according to the vessel blood changing feature to generate a physiological signal. | 08-01-2013 |
20140014824 | NON-LENS PACKAGE STRUCTURE FOR AN OPTICAL DEVICE - A packaged optical device includes a package frame having a compartment and an opening, a sensor chip bonded in the compartment, and a non-lens transparency layer embedded in the package frame at the opening and sealing up the opening. This package structure could prevent the sensor chip from adhesion of suspended particles or other contaminations, and simply the assembly process, thereby improving reliability and reducing cost of the packaged optical device. | 01-16-2014 |
20140098377 | IMAGE RETRIEVING APPARATUS AND OPTICAL DISPLACEMENT ESTIMATING APPARATUS - An image capturing apparatus comprising: a light source, for transmitting incident light to an objective without utilizing any medium besides air, such that the light emits from the objective to generate passing-through light; and a sensor, for capturing an image of the objective according to the passing-through light. | 04-10-2014 |
20140133876 | EXPOSURE ADJUSTING APPARATUS, IMAGE NORMALIZING APPARATUS AND IMAGE NORMALIZING METHOD - An exposure adjusting apparatus, which comprises: an image sensor, for catching an image according to an exposure parameter; a computing apparatus, for computing an exposure amount of the image and for determining whether the exposure amount is in a predetermined exposure range or not; and an exposure updating apparatus. If the exposure amount is in the predetermined exposure range, the exposure updating apparatus does not adjust the exposure amount. If the exposure amount is not in the predetermined exposure range, the exposure updating apparatus generates at least one adjusting amount according to at least one of the predetermined exposure range, the exposure amount and the exposure parameter, and utilizes the adjusting amount to increase or decrease the exposure parameter to generate a new exposure parameter. | 05-15-2014 |
20140160017 | ELECTRONIC APPARATUS CONTROLL METHOD FOR PERFORMING PREDETERMINED ACTION BASED ON OBJECT DISPLACEMENT AND RELATED APPARATUS THEREOF - An electronic apparatus controlling method includes: determining if displacement of an object in a first predetermined time period is smaller than a first predetermined distance to generate a determining result; and controlling the electronic apparatus to perform a first predetermined action if the determining result is no, and controlling the electronic apparatus to perform a deciding step if the determining result is yes. The deciding step is utilized for deciding if a second predetermined action is performed according to a coordinates of the object at the end of the first predetermined time period. | 06-12-2014 |
