An accessory unit is mounted on an electronic camera, and a printer connects to the electronic camera via a SCSI terminal of the accessory unit. An image signal is captured from a CCD in response to the releasing operation, and the image signal is analog-to-digital converted before being transferred to the accessory unit. The accessory unit converts the image signal into RGB data suitable for the printer, and outputs the RGB data to the printer so that the captured image can be simultaneously with the image-capturing. Moreover, during sequential image-capturing, captured image data is sequentially stored in an uncompressed state in a frame memory of the accessory unit. After sequential image-capturing is completed, the image data is transferred to the camera in an order in which it is stored, and compressed. Further, a background image is recorded in a memory card in advance, and an image is composed from the background image and a captured image (or a reproduced image) in the accessory unit. The composite image data is then transferred to the printer.

Electronic camera accessory and image composition system

An image quality correction circuit for use with an imaging apparatus which converts a luminance signal so that an intermediate portion of the signal between preset minimum and maximum values is extended. The invention also relates to a device where color difference signals are corrected in accordance with the same nonlinear characteristic utilized in the correction of the luminance signal.
