Abstract
An image pickup apparatus of which the display start timing and the display quality are selectable. The image pickup apparatus has a switch which selectively switches display data to be displayed on a display device between the first display data output by the first output circuit, and the second display data output by the second output circuit, and display the first display data or the second display data on the display device, wherein the first display data is generated by the image data output by the image pickup device developed, and the second display data is generated by the image data transferred by a transfer circuit developed.
Claims10
An image pickup apparatus comprising:
- an image pickup device which converts a received light into an electrical signal to output image data;
- a first memory which stores the output image data;
- a first development circuit which develops the output image data to generate first display data;
- a second development circuit which develops the output image data to generate second display data which has larger amount of data than that of the first display data;
- a second memory which stores the output image data or the second display data developed by the second development circuit;
- a first transfer circuit which transfers the image data stored in the first memory to the second memory;
- a second transfer circuit which transfers the first display data to a display device;
- and
- a third transfer circuit which transfers the second display data stored in the second memory to the display device,
- wherein the second development circuit and the third transfer circuit are in a power-saving mode while the first display data is displayed on the display device.
A method of controlling an image pickup apparatus comprising:
- converting a received light into an electrical signal to output image data;
- storing, in a first memory, the output image data;
- developing, via a first development circuit, the output image data to generate first display data;
- developing, by a second development circuit, the output image data to generate second display data which has a larger amount of data than that of the first display data;
- storing, in a second memory, the output image data or the second display data developed by the second development circuit;
- wherein the image data stored in the first memory is transferred to the second memory via a first transfer circuit,
- wherein the first display data is transferred to a display device via a second transfer circuit;
- wherein the second display data stored in the second memory is transferred, via a third transfer circuit, to the display device;
- and
- wherein the second development circuit and the third transfer circuit are in a power-saving mode while the first display data is displayed on the display device.
