a projection apparatus includes a plurality of light sources individually emitting light in a plurality of colors , a projection section using light from the light sources to generate images corresponding to respective plural color components of the light source light for each period , to sequentially project the images , a measurement section measuring a brightness of the light sources for each of the plurality of colors , an average brightness calculation section calculating , at each image projection term for the same color component , an average brightness of the brightness measured by the measurement section at the image projection term , and a light source control section adjusting the brightness of the light sources so that an average chromaticity based on the average brightness calculated by the average brightness calculation section and indicating the brightness is equal or approximate to a target chromaticity .
