Patent number: 9454257Abstract: An electronic system includes a device having a screen and an optical touch device. The optical touch device monitors the activity of an object on the screen of the device. When the object performs an operation in a first region of the screen, the optical touch device generates first data; and when the object performs an operation outside the first region, the optical touch device generates second data, wherein the first data and the second data are of different data types.Type: GrantFiled: March 1, 2013Date of Patent: September 27, 2016Assignee: PIXART IMAGING INC.Inventors: Chun Yi Lu, Tzung Min Su, Yuan Yu Peng, Yi Hsien Ko

Patent number: 9151599Abstract: The present invention provides an image sensing module including an image sensing device and a calculation device. The image sensing device includes a plurality of pixels for acquiring an operation image containing an object image. The calculation device stores a look-up table regarding a temperature related parameter and a position deviation of the object image at each pixel associated with the temperature related parameter, and selects a deformation error from the look-up table according to the temperature related parameter corresponding to the operation image so as to correct a current position of the object image in the operation image.Type: GrantFiled: April 29, 2011Date of Patent: October 6, 2015Assignee: PIXART IMAGING INC.Inventors: Cheng Nan Tsai, Chun Yi Lu, Hui Hsuan Chen, Hung Ching Lai, Yuan Yu Peng, Tsung Min Su, Chih Hsin Lin, Yu Chia Lin, Teng Wei Hsu, Chuan Ching Lin

Publication number: 20130265283Abstract: An optical operation system includes an image sensing apparatus and a processing circuit. The image sensing apparatus is disposed at an edge of an operation plane and includes a first sensing array and a second sensing array. The first sensing array is configured to capture images at a first height above the operation plane and accordingly generate a first output signal. The second sensing array is configured to capture images at a second height above the operation plane and accordingly generate a second output signal; wherein the first height is greater than the second height. The processing circuit is electrically connected to the image sensing apparatus and configured to receive the first output signal and the second output signal and accordingly generate a first control command and a second control command, respectively.Type: ApplicationFiled: August 15, 2012Publication date: October 10, 2013Applicant: PixArt Imaging Inc.Inventors: CHUN-YI LU, Yuan-Yu Peng, Yu-Chia Lin, Tzung-Min Su

Publication number: 20120120024Abstract: A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system.Type: ApplicationFiled: June 7, 2011Publication date: May 17, 2012Applicant: PixArt Imaging Inc.Inventors: Yu-Chia Lin, Tzung-Min Su, Cheng-Nan Tsai, Chih-Hsin Lin, Teng-Wei Hsu, Yuan-Yu Peng, Chuan-Ching Lin
