Array camera
Disclosed is an array camera. The array camera includes an array camera comprising an image sensor sectioned into at least two channels and at least two lens modules each positioned on a top of one of the channels. Each channel consists of an active sensor area and a dead space. Each lens module has a barrel. Each barrel of the lens modules has an inner sidewall facing the adjacent lens modules and an outer sidewall opposite to the inner surface. Wherein, a projection of the inner sidewall of each barrel along the optical axis is an inner line on the corresponding channel of the image sensor and the inner line is substantially superposed with a part of the outline of the active sensor. The array camera has a small size.
1. An array camera comprising:
an image sensor sectioned into at least two channels, each channel consisting of an active sensor area and a dead space; and
at least two lens modules each positioned on a top of one of the channels, each lens module having a barrel, each barrel of the lens modules having an inner sidewall facing the adjacent lens modules and an outer sidewall opposite to the inner surface, each of the lens modules imaging a view of the scene directly on to a corresponding area of the image sensor;
wherein, a projection of the inner sidewall of each barrel along the optical axis is an inner line on the corresponding channel of the image sensor and the inner line is substantially superposed with a part of the outline of the active sensor.
2. The array camera as described in claim 1 , wherein the lens module is realized as a wafer-level lens module.
3. The array camera as described in claim 1 , wherein the outer sidewall of each lens modules is configured to be a part of a circle.
4. The array camera as described in claim 1 , wherein the inner sidewall of each lens module comprises a first inner sidewall and a second inner sidewall perpendicular to the first inner sidewall.
5. The array camera as described in claim 1 , wherein each lens module has a first distance between the inner sidewall and a center of the corresponding lens module and a second distance between the outer sidewall and a center of the corresponding lens module, the first distance is smaller than the second distance.
