Wide band light sensing pixel array |
摘要 |
In a wide band light sensing pixel array (100) comprising pixel groups (105), a ratio of a visible exposure period to a near infrared exposure period is controlled by a control circuit (108) to be essentially equivalent to a ratio of a second nominal sensitivity to a first nominal sensitivity. The visible exposure period is an exposure period of a set of visible light pixels having the first nominal sensitivity. The near infrared exposure period is an exposure period of a near infrared light pixel having the second nominal sensitivity. A subset of the set of visible light pixels and the near infrared light pixel in each pixel group (105) and circuit components associated only with the subset can be turned off during a reduced color mode.
