1. A camera, comprising a filter and a sensor, wherein
the filter is configured to output target optical signals of different bands in optical signals incident on the filter to a same pixel on the sensor at different times; and
the sensor is configured to: convert the target optical signals incident on the sensor into electrical signals, and output the electrical signals;
wherein the filter comprises a first motor and a plurality of filters, the plurality of filters installed on a first electric wheel of the first motor,
each of the plurality of filters is configured to output a target optical signal in the optical signals incident on the filter, and bands of target optical signals output by different filters in the plurality of filters are different; and the first motor is configured to move, at different times, different filters in the plurality of filters with the first electric wheel of the first motor to target positions at which the optical signals are received; or
wherein the filter comprises a second motor and a linear graded interferometric filter, the linear graded interferometric filter fastened to a second electric wheel of the second motor,
the second motor is configured to move, at different times, different parts of the linear graded interferometric filter with the second electric wheel of the second motor to target positions at which the optical signals are received, and bands of target optical signals output by the different parts of the linear graded interferometric filter fail for passing the linear graded interferometric filter.
