Patent ID: 8125534

Claim:
An image processing apparatus which performs image processing on images created by image pickup at a first image frame rate which can visually recognize images and, also, performs image processing on images created by image pickup at a second image frame rate higher than the first frame rate, the image processing apparatus comprising: a mode selection unit which selects one of a magnification observation mode for observing an object at the first frame rate by magnifying it and a high-speed photographing mode for photographing a moving object at a high speed at the second frame rate; an image pickup unit which is capable of capturing images at the first and second frame rates and performs image pickup on an object at the first or second frame rate selected by the mode selection unit; a frame-rate conversion unit which performs processing for decreasing the frame rate of image data of an object, the image data of the object created by image pickup at the first or second frame rate corresponding to the mode selected by the mode selection unit being transferred to the frame-rate conversion unit, by the image pickup unit; a first memory into which image data at the second frame rate from the image pickup unit is written during recording operations in the high-speed photographing mode; a moving-image readout unit which reads out image data from the first memory during readout of image data from the first memory in the high-speed photographing mode; an image processing unit which performs processing for adjusting luminance levels on image data subjected to the frame-rate conversion by the frame-rate conversion unit to create display data and, also, performs processing for adjusting luminance levels on image data read out from the first memory by the moving-image readout unit; a changeover unit which connects one of the frame-rate conversion unit and the moving-image readout unit to the image processing unit and, also, connects the moving-image readout unit to the image processing unit only when image data is read out from the first memory by the moving-image readout unit; a display unit which displays display data created by the image processing unit; and a second memory which stores respective images when image data displayed on the display unit is stored and when image data in the first memory is stored in the magnification observation mode.
