Day and Night Detection Based on One or More of Illuminant Detection, Lux Level Detection, and Tiling
First Claim
1. A method for controlling a camera mode, comprising:
- in a camera including a controller, memory storing instructions for execution by the controller, a sensor array comprising a plurality of sensors, an IR filter, and a lens assembly that is configured to focus light on the sensor array;
operating the camera in a night mode, wherein while in the night mode the IR filter is not interposed between the lens assembly and the sensor array, including;
receiving at the sensor array ambient light that is not filtered by the IR filter;
determining whether the received ambient light is due to a light source other than an IR light source;
detecting a light level of the received ambient light;
based on a determination that the received ambient light is due to a light source other than an IR light source and that the light level of the received ambient light exceeds a first threshold, switching the operation of the camera from the night mode to a day mode; and
based on a determination that the received ambient light that is due to a light source other than an IR light source and that the light level of the received ambient light does not exceed the first threshold, continuing operation of the camera in the night mode.

Abstract
A method for controlling a camera mode is executed at a camera including a controller, a sensor array, an IR filter, and a lens assembly. The camera is operated in a night mode. While in the night mode the IR filter is not interposed between the lens assembly and the sensor array, the camera receives at the sensor array ambient light that is not filtered by the IR filter, determines whether the received ambient light is due to a light source other than an IR light source, and detects a light level of the received ambient light. The camera switches the operation of the camera from the night mode to a day mode when it is determined the received ambient light is due to a light source other than an IR light source and that the light level of the received ambient light exceeds a first threshold.

10. A camera mode control system for a camera, comprising:
-
a controller, memory storing programs for execution by the controller, a sensor array comprising a plurality of sensors, a lens assembly that is configured to focus light on the sensor array, and an IR filter; the one or more programs including instructions for; operating the camera in a night mode, wherein while in the night mode the IR filter is not interposed between the lens assembly and the sensor array, including; receiving at the sensor array ambient light that is not filtered by the IR filter; determining whether the received ambient light is due to a light source other than an IR light source; detecting a light level of the received ambient light; based on a determination that the received ambient light is due to a light source other than an IR light source and that the light level of the received ambient light exceeds a first threshold, switching the operation of the camera from the night mode to a day mode; and based on a determination that the received ambient light that is due to a light source other than an IR light source and that the light level of the received ambient light does not exceed the first threshold, continuing operation of the camera in the night mode. - View Dependent Claims (11, 12, 13, 14)

16. A non-transitory computer readable storage medium storing one or programs for execution by a camera system including a controller, a sensor array comprising a plurality of sensors, a lens assembly that is configured to focus light on the sensor array, and an IR filter that is not interposed between the lens assembly and the sensor array in a night mode, the one or more programs comprising instructions for:
operating the camera in a night mode, wherein while in the night mode the IR filter is not interposed between the lens assembly and the sensor array, including; receiving at the sensor array ambient light that is not filtered by the IR filter; determining whether the received ambient light is due to a light source other than an IR light source; detecting a light level of the received ambient light; based on a determination that the received ambient light is due to a light source other than an IR light source and that the light level of the received ambient light exceeds a first threshold, switching the operation of the camera from the night mode to a day mode; and based on a determination that the received ambient light that is due to a light source other than an IR light source and that the light level of the received ambient light does not exceed the first threshold, continuing operation of the camera in the night mode. - View Dependent Claims (17, 18, 19, 20)
