Image pickup apparatus
First Claim
1. An image pickup apparatus comprising:
- a taking lens;
an image pickup device;
defect pixel detection means for detecting defect pixels occurring on the image pickup device; and
incident light condition detecting means for detecting the condition of incident light onto said image pickup device, wherein said defect pixel detection means detects defect pixels in a time period during which an image taken by main exposure requiring a recording by said image pickup device cannot be obtained, and wherein said defect pixel detection means detects defect pixels when a condition that light incident on said image pickup device is very small in amount is being detected by said incident light condition detecting means.

Abstract
An image pickup apparatus is constructed as including: a taking lens; CCD image pickup device for converting object light into electrical signals; AD converter for converting image pickup signals into digital signals; a defect detecting section for detecting defect pixels in the digital image pickup signals; a defect correcting section for performing correction processing of the defect pixels detected at the defect detecting section; and a system controlling section for managing the operation of the entire system. The taking lens is attachable/detachable and interchangeable and a function is provided at the system controlling section to detect attachment/detachment of the taking lens. The defect detecting section is caused to perform defect detection when the taking lens has been detached so that the power consumption is reduced and at the same time a missing of image taking chance due to defect detection is prevented.
