Patent number: 7750951Abstract: An image sensor repeatedly receives a light from an object through a lens and generates images of the object. A differential image generating unit generates a differential image from at least two images. A detector detects a change cycle or an intensity of an external light. An evaluation unit evaluates an influence of the external light and derives an optimal timing in which a minimum influence of the external light is attained. A controller controls a timing of receiving the light of the image sensor, depending upon the optimal timing derived by the evaluation unit, and repeatedly synchronizes a term of two timings with the change cycle of the external light by shifting the term into the change cycle by a unit of predetermined phase difference.Type: GrantFiled: February 11, 2008Date of Patent: July 6, 2010Assignee: Kabushiki Kaisha ToshibaInventors: Shunichi Numazaki, Miwako Doi, Minoru Ishikawa, Akira Morishita, Naoko Umeki

Patent number: 7453511Abstract: An area image sensor outputs the difference between charges received by light-receiving cells arranged in an array pattern. A system controller generates a timing signal for generating a pulse or modulation signal. A control signal generator generates a control signal for separately controlling the light-receiving timings of the light-receiving cells of the area image sensor on the basis of the timing signal from the system controller. A light emitting controller controls a light source to generate light, the intensity of which changes on the basis of the timing signal from the system controller. A reflected light image processor extracts a reflected image of an object from the difference outputted from the area image sensor.Type: GrantFiled: August 21, 2003Date of Patent: November 18, 2008Assignee: Kabushiki Kaisha ToshibaInventors: Shunichi Numazaki, Miwako Doi, Yoshiyuki Matsunaga, Akira Morishita, Naoko Umeki
