Abstract
There is provided a reading apparatus that includes a conveyance roller, a light source, a light transmission member, a line sensor having a plurality of pixels and configured to receive reflected light from a sheet via the light transmission member while the sheet is conveyed by the conveyance roller, and a controller. The controller is configured to perform acquiring an output value of a first pixel, an output value of a second pixel, and an output value of a third pixel, determine a first value based on the output value of the second pixel and a first coefficient, determine a second value based on the output value of the third pixel and a second coefficient, and determine read data based on the output value of the first pixel, the first value, and the second value. The first coefficient is larger than the second coefficient.
