| 发明名称 | Image sensor positioning apparatus and method | ||
| 摘要 | A method is provided for positioning an image sensor having a light receiving plane within a camera and a system is provided for identifying the position of an image sensor. The method comprises projecting a first group of substantially parallel light beams representing a first predetermined pattern onto the light receiving plane of the image sensor at an angle of incidence, projecting a second group of substantially parallel light beams representing a second predetermined pattern onto the light receiving plane of the image sensor at an angle of incidence, registering positions on the light receiving plane of the image sensor where the light beams are detected by the image sensor, generating adjustment information based on the registered positions, indicating if the present position of the image sensor is an erroneous position or not, and adjusting the position of the image sensor based on the adjustment information. | ||

| 主权项 | 1. A method for positioning an image sensor including a light receiving plane within a camera, the method comprising: projecting a first group of collimated light beams representing a first predetermined pattern onto the light receiving plane of the image sensor at an angle of incidence α1 for the first group; projecting a second group of collimated light beams representing a second predetermined pattern onto the light receiving plane of the image sensor at an angle of incidence α2 for the second group, wherein at least one of the predetermined patterns includes parallel lines having a length stretching from one edge of the effective surface of the image sensor to an opposite edge of the effective surface of the image sensor; registering positions of the projected light beams on the light receiving plane of the image sensor; generating adjustment information, based on the registered positions, indicating if the present position of the image sensor is an erroneous position or not; and adjusting the position of the image sensor based on the adjustment information. | ||
