1. An image generation apparatus comprising:
an image data generating section configured to generate data of a display image;
a frame buffer configured to store data of an image generated;
a format control section configured to, in a case where the image data generating section executes alpha compositing of a plurality of images, switch a data format of pixel values to be stored in the frame buffer; and
an output section configured to read the data of the image from the frame buffer, convert the data into a format corresponding to a display, and output resulting data,
wherein the format control section switches the data format by changing:
whether a decimal point of the data to be stored is fixed or floats, and
the number of bits to be assigned to each color.
