An image processing method for extracting a subject from an image including the subject using a background image includes: generating a background removed image obtained by removing a background region not including the subject in the image from the image; compressing the background removed image; transmitting the background removed image compressed via a network; receiving the background removed image compressed via the network; decoding the background removed image compressed and received; generating a restored image by synthesizing the background removed image decoded and the background image; and comparing the restored image with the background image to extract the subject.

A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule. The predetermined arrangement rule is an arrangement rule employed when respective frame data constituting a video signal having a second frame rate equal to or lower than the standard frame rate are arranged in a duplicating manner in the standard video signal. In the foregoing manner, an time elongation/contraction effect on an image can be speedily and inexpensively obtained.

In an imaging apparatus, unevenness in brightness in screen due to flash is eliminated and video with secured continuity as a moving image can be obtained. In the imaging apparatus (), signals of fields affected by flash among video signals acquired by imaging are treated with adding or adding and averaging to equalize effects of flash which appear unevenly on a screen.

The line buffer stores an input image after a change is made to the stored line position of each horizontal segment. The stored-line position memory unit stores the stored line position of each horizontal segment in the line buffer. The vertical interpolator performs vertical interpolation on each of outputs of the line buffer based on the differences between the vertical interpolation line positions and the stored line positions. Thus, the number of lines needed for vertical interpolation to be stored in the line buffer can be reduced.

Image processing device

A video signal producing system includes an imaging device for obtaining progressive imaging signals having various frame rates, a recording device for recording an output signal of the imaging device and a reproduction device for reproducing a recording signal obtained from the recording device. The imaging device includes a frame rate converting portion for converting the imaging signals to an output having a predetermined frame rate and the reproduction device changes a reproduction speed in response to each of the various frame rates so as to generate an output having a substantial number of frames such that the substantial number of the frames assumes a predetermined value.

An imaging device uses a solid state imaging element, during multi-field accumulation to prevent shading and oscillatory phenomena such as repeated black and white patterns. A signal is supplied from a timing signal generation circuit to switches, and controls the ON/OFF operation. During the H period of the signal, the switch is closed, and the output value of an amplifier is input to a capacitor. During the L period of the signal, the switch is opened, and the average value of the output of the amplifier is maintained in the capacitor. During the H period, the switch is open, while during the L period, the switch is in the ON state. At this time, the level of the capacitor Cand the output of the amplifier are input to an amplifier, and their difference is amplified and supplied to a capacitor Cvia the switch.

A solid-state image sensing device comprising a photoelectric converter portion, a solid-state image sensor, and a controlling means. The photoelectric converter portion has a plurality of photoelectric converters arranged in two dimensions on a semiconductor substrate. The solid-state image sensor vertically transfers charges, transferred from the photoelectric converter portion, at separate times of first transfer and second transfer. Further, the photoelectric converter portion has a vertical transfer portion, in which first and fourth gates are provided for odd-numbered photoelectric converters, and second and third gates are provided for even-numbered photoelectric converters, and a horizontal transfer portion for horizontally transferring charges transferred from the vertical transfer portion. The controlling means supplies the vertical transfer portion with vertical transfer pulses and the horizontal transfer portion with horizontal transfer pulses. The controlling means transfers charges from the photoelectric converter portion to the vertical transfer portion such that the charges of odd-numbered pixels and the charges of even-numbered pixels are each transferred in a lump, respectively.
