Abstract: A digital camera is provided that includes an imaging device that takes a picture of a subject's image and generates an image signal, an image signal processor that performs predetermined conversion and compression processes on the image signal and generates digital image information, a storage device that stores the digital image information, a setting device that sets the resolution and compression ratio at which the image signal is processed by the image signal processor, and a control device that sends the resolution and compression ratio set by the setting device to the image signal processor. In the digital camera, the image signal processor changes either the resolution or compression ratio, or both, when the storage device has an insufficient space to store new images.
