first embodiment
aratus
[0080]Detailed description will first be made of an image pickup apparatus to which the present invention can be applied. It is to be noted that while the description will be made by taking an example of a video camera capable of color pickup of a still image and / or a moving image as the image pickup apparatus according to the present embodiment, the present invention is not limited to the embodiment.
[0081]FIG. 1 is a block diagram schematically showing the image pickup apparatus 100 according to the first embodiment. The image pickup apparatus 100 includes a lens part 110, a prism part 112, CCD units 114, A / D converter units 116, a linear matrix circuit 118, an image enhancing unit 120, adders 122, knee circuits 124, gamma circuits 126, clipping circuits 128, a Y matrix circuit 130, an MPEG encoder 132, a buffer memory 134, a formatter 136, a disk unit 138, an MPEG decoder 140, and a reproduction displaying unit 142.
[0082]The lens part 110 includes optical parts that form an ...
second embodiment
(Image Pickup Apparatus 300)
[0110]FIG. 3 is a block diagram schematically showing an image pickup apparatus 300 according to the second embodiment. The image pickup apparatus 300 includes an image pickup unit 310, an image pickup rate controlling unit 312, a line reducing unit 314, an encoder 316, an image storing unit 318, and a picked-up image displaying unit 320.
[0111]The image pickup unit 310 includes for example the lens part 110, the prism part 112, and the CCD units 114 described in the first embodiment. The image pickup unit 310 obtains a picture by picking up an image of a subject. The picked-up image is transferred serially in pixel units. In addition, as required, the image pickup unit 310 can include the A / D converter units, the linear matrix circuit, the image enhancing unit, the adders, the knee circuits, the gamma circuits, the clipping circuits, the Y matrix circuit and the like described in the first embodiment.
[0112]The image pickup rate controlling unit 312 ...
third embodiment
[0140]Description will next be made of an image processing system when images of high image quality are obtained in low-speed image pickup.
(Image Pickup Apparatus 500)
[0141]FIG. 8 is a block diagram schematically showing an image pickup apparatus 500 according to a third embodiment. The image pickup apparatus 500 includes an image pickup unit 310, an image pickup rate controlling unit 512, a line adding unit 514, an encoder 316, an image storing unit 318, and a picked-up image displaying unit 320.
[0142]The image pickup unit 310, the encoder 316, the image storing unit 318, and the picked-up image displaying unit 320 have substantially the same functions as the image pickup unit 310, the encoder 316, the image storing unit 318, and the picked-up image displaying unit 320 already described as constituent elements in the second embodiment, and therefore repeated description thereof will be omitted. Description in the following will be made mainly of the image pickup rate controll...
