Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, an image pickup apparatus, a control method thereof, and a medium such as a memory medium. The present invention relates to a control method thereof and a medium such as a memory medium used for the control.

[0002]

2. Description of the Related Art There is an image processing apparatus such as an electronic camera for recording and reproducing a still image or a moving image captured by a solid-state image sensor such as a CMOS or a CCD using a memory card having a solid-state memory device as a recording medium.

According to these electronic cameras, captured image data can be recorded on a recording medium such as a flash memory or a hard disk.

When an image is picked up using a solid-state image pickup device such as a CMOS or a CCD, dark image data read out after charge accumulation is performed in the same manner as in actual photographing without exposing the image pickup device, and in a state where the image pickup device is exposed. It is possible to perform dark noise correction processing by performing arithmetic processing using the main photographed image data read after charge accumulation.

When an image is picked up using a solid-state image pickup device such as a CMOS or a CCD, white spots and black data are always output because white data is always output due to minute pixel defects of the image pickup device. It is possible to perform a point flaw correction process by performing an interpolation calculation process on data of a defective pixel using data of an adjacent pixel using position information of a pixel relating to a black spot flaw caused by the above.

By these correction processes, CMOS, CC
With respect to image quality deterioration such as dark current noise generated by an image sensor such as D and pixel defects due to minute scratches inherent to the image sensor, high quality images can be obtained by correcting captured image data.

[0007] Some of these electronic cameras can take a picture by changing taking lenses having different focal lengths and open aperture values according to the purpose.

[0008]

In such a conventional image processing apparatus such as an electronic camera, it is necessary to know in advance the position information of a defective pixel at the time of photographing. However, there is a problem that correction cannot be performed when the number of defective pixels increases in accordance with the above.

On the other hand, in the method of detecting the position of a defective pixel when the shutter switch is pressed, correction can be performed even when the number of defective pixels increases with time, but the shutter release time lag is reduced. However, there is a problem that the time for detecting the position information of the defective pixel becomes longer by the time for detecting the position information of the defective pixel, or the interval between successive photographing becomes longer by the time for detecting the position information of the defective pixel.

When photographing is performed by arbitrarily mounting photographing lenses having different focal lengths and open aperture values, the photographing lens used depends on the exit pupil distance, the aperture value at the time of photographing, and the focal length at the time of photographing. Since the angle of the luminous flux incident on the image sensor is different between the central pixel and the surrounding pixels of the image sensor, vignetting occurs in the light incident on the light detection unit of each pixel of the image sensor,
There has been a problem that luminance shading and color shading may occur in the image signal output of the image sensor.

The present invention has been made in view of the above background, and one aspect thereof is to correct, for example, a newly generated pixel defect and to speed up a photographing operation.

Another object of the present invention is to obtain an image in which the shading of the lens unit is corrected irrespective of, for example, a change in the state of the lens unit.

If 2 is ON (S839), the process proceeds to S861.

The system control circuit 50 determines whether or not there is an image storage buffer area capable of storing captured image data in the memory 30 (S861), and stores new image data in the image storage buffer area of the memory 30. If there is no available area, a predetermined warning is issued by image or sound using the output unit 54 (S862), and the process returns to S802. Here, when there is no area capable of storing new image data in the image storage buffer area of the memory 30,
For example, immediately after performing the maximum number of continuous shootings that can be stored in the image storage buffer area of the memory 30, the first image to be read from the memory 30 and written to the storage medium 200 or 210 is still stored in the storage medium 200 or 210. For example, there is a case where the image is in an unrecorded state, and one empty area cannot be secured in the image storage buffer area of the memory 30 yet.

When the photographed image data is compressed and stored in the image storage buffer area of the memory 30, the amount of compressed image data differs depending on the setting of the compression mode. The area that can be stored is memory 3.
