Filter mounting methods and apparatus and related camera apparatus
First Claim
1. An apparatus for use in a camera device, the apparatus comprising:
- a filter mount (1106) including sidewalls (1309, 1309′
, 1306, 1306′
) forming a filter well (1110) for mounting a filter (1114), said sidewalls including outer support walls (1309, 1309′
) extending from a surface (1103) of a mounting board (1102) to a top (1106′
) of said filter well (1110), inner sidewalls (1306, 1306′
) of said filter mount (1106) extending inward from the outer support walls (1309, 1309′
) to form a support ledge (1111) for supporting the filter (1114) in the filter well (1110); and
the filter (1114) positioned in said filter well (1110), said filter (1114), filter mount (1106) and mounting board (1102) forming a cavity (1357) in which a sensor (1307) is mounted to said mounting board (1102), and wherein at least one corner (1126) of said filter mount (1106) is open for ventilation of the cavity (1357).

Abstract
Methods and apparatus, for mounting and using a filter over an image sensor are described as well as camera modules and apparatus incorporating the filter mount. Also described is a sensor and filter assembly which can be formed by combining the sensor, filter, filter mount, and a mounting board which can be shipped and integrated into a camera module and/or camera. A filter is placed in a filter well of a filter mount. By using a well to support the filter over a sensor, the top of the filter can be level or below the top of sidewalls of the filter mount. Use of a well to mount the filter reduces the risk of stray or unintentionally reflected light reaching the sensor and degrading captured images while protecting the filter from downward pressure or sideways contact.
