Patent number: 9063011Abstract: A method of signal adjustment in an optical sensing device is provided. The optical sensing device includes a first optical sensor and a first reference optical sensor. The first optical sensor corresponds to a first specified ideal spectral response and generates a first output signal corresponding to light detected thereby. The first reference optical sensor generates a first reference signal corresponding to light detected thereby, and is disposed adjacent to the first optical sensor such that the light detected by the first reference optical sensor is substantially the light detected by the first optical sensor. The method includes the steps of: a) receiving the first output signal and the first reference signal; and b) generating a first adjusted output signal having a spectral response that approximates the first specified ideal spectral response, by adjusting the first output signal according to the first reference signal.Type: GrantFiled: March 29, 2011Date of Patent: June 23, 2015Assignee: Dyna Image CorporationInventors: Meng-Kun Chen, Chun-Hsien Lin, Yi-Tsung Li

Publication number: 20100163713Abstract: An electromagnetic wave sensing device and an operating method for the same are disclosed. The claimed device integrates signal transformation, operation and a sensing range configuration. Particularly, the sensing apparatus at least has two sensing units that respectively sense the ambient light and the electromagnetic wave with a specific range of spectrum. Moreover, a temperature sensor is further introduced to compensate the sensed signals by eliminating the temperature influence. Since the output of the sensing device can have a stable characteristic, the downstream manufacturers don't need to use different hardware or software to adapt different product conditions. The preferred embodiment is to provide one electromagnetic wave sensing device having at least two sensing units for respectively sensing different ranges of electromagnetic waves. After signal transformation, the signals are outputted according to the working mode configured by a control unit.Type: ApplicationFiled: January 7, 2010Publication date: July 1, 2010Applicant: LITE-ON SEMICONDUCTOR CORP.Inventors: CHIA-CHU CHENG, PO-CHENG CHANG, MENG-KUN CHEN, CHIA-CHENG LEI, HSING-YEN WU

Publication number: 20090273048Abstract: An image-sensing chip package module adapted to dual-side soldering includes three substrates, an image-sensing chip and a filter lens. The three substrates are stacked together by pressing (using adhesive as adhesion medium), and the image-sensing chip is electrically connected to the top side of the top substrate and the bottom side of the bottom substrate via conductive bodies that are formed on inner surfaces of through holes passing through the three substrates. Hence, the image-sensing chip package module can use the conductive bodies formed on the bottom side of the bottom substrate (positive face electrical conduction) or the conductive bodies formed on the top side of the top substrate (negative face electrical conduction) to electrically connect with a main PCB. Furthermore, the filter lens is received and hidden in an opening of the top substrate in order to prevent the filter lens from being slid, collided and destroyed.Type: ApplicationFiled: May 5, 2008Publication date: November 5, 2009Inventor: Meng-Kun Chen
