The present invention provides a camera where a focusing position of a taking
lens is adjusted as a first focus adjustment by a CPU, and as a second focus adjustment
lower in accuracy but higher at a speed than the first focus adjustment. An object
image is picked up through the taking lens by an imager, and an output signal of
the imager is converted into image data. A compressibility of the image data obtained
at the imager is set by an image processing section, and the image data is compressed
in accordance with the set compressibility. Then, in accordance with the compressibility
set by the image processing section, the CPU decides which of the first focus adjustment
and the second focus adjustment is used to execute a final focus adjustment operation
of the taking lens.
