Abstract
For obtaining both still and moving images in satisfactory manner in an image pickup device, in addition to a circuit for generating a moving image, frame recursive filters 18, 19, 20 and an interface circuit 21 are provided for generating a still image. Wide-band color signals R, G, B generated from the signals obtained from the CCD are subjected to a filtering process in the frame recursive filters 18, 19, 20 and the image retained in the filters 18, 19, 20 as a result of the filtering process is released as a still image under the control by the interface circuit 21. Thus the still and moving images can be generated respectively according to the required characteristics, without color blotting or color aberration and without deterioration in the color reproducibility and in the S/N ratio.
Claims4
An image pickup device provided with an image sensor element from which the signals of all the pixels are read in a non-interlaced manner, without being added together, in a field period and adapted to generate a moving image based on the signals from said image sensor element, comprising:
- an A/D converter for converting a non-interlaced output of said image sensor element into a digital image signal;
- interlacing means for converting said non-interlaced output from said A/D converter into different interlaced signals field-by-field;
- filter means for filtering said interlaced signals with a predetermined filtering characteristic controlled by an external device;
- and
- a pixel size conversion circuit for converting a pixel size of an output of said filtering means.
