Abstract:
1. An image sensor, comprising: a line sensor including sensor elements that are arranged in one line and are configured to acquire, in each line cycle, a plurality of R signals, a plurality of G signals and a plurality of B signals, when light sources, each corresponding to one of R, G and B colors, in the each line cycle, sequentially illuminate one after another in a predetermined order and repeat this sequential illumination in the predetermined order; a buffer that includes data saving units, each corresponding to one of the R, G and B colors; a controlling unit configured to generate, from the plurality of R signals, the plurality of G signals and the plurality of B signals acquired by the sensor elements a plurality of R data, a plurality of G data and a plurality of B data in each line cycle, and to add each of the plurality of R data, the plurality of G data and the plurality of B data in each cycle in a corresponding one of the data saving units; and an output unit configured to sequentially output to outside, as RGB line data, the plurality of R data, the plurality of G data and the plurality of B data in each line cycle that have been saved in the data saving units, wherein
