摘要： In an image signal converter (ICp1) converting a component video signal (Scv) of an interlaced scanning format for image display on a display device for an image signal of a progressive scanning format (Scv, p) for image display on the display device, an up-converter (11) converts the component video signal (Scv) of the interlaced scanning format into the one of the progressive scanning format. A scanning format determination part (4, 14, 15) determines based on a luminance signal (Y) included in the component video signal (Scv1, Scv2) whether the component video signal (Scv1, Scv2) is of the interlaced or progressive scanning format. Based on the determination result of the scanning format determination part (15), an output destination selector (3B, 15A) selects an output destination of the component video signal (Scv1, Scv2). When the scanning format determination part (15) determines that the format is the interlaced scanning format, the component video signal (Scv1, Scv2) is supplied to the up-converter (11).

摘要： A digital camera with video input is disclosed. An image sensor is provided to capture an image and convert the captured image into R/G/B image signals the are processed by a video signal processing unit for being converted into pixel data having a first format. A TV decoder converts input analog video signals into pixel data having a second format. A scaling unit performs aspect ratio processing and zoom/pan function to pixel data. A TV interface unit converts pixel data having the second format into pixel data having the first format for being selectively output to the scaling unit directly and output to the scaling unit after transferring to the video signal processing unit for performing edge enhancement. A compressing and storage unit performs compress operation to the pixel data output from the video signal processing unit and the scaling unit. An USB unit converts pixel data after being compressed into serial data for output.

摘要： A method and system for capturing live video signal data using bufferless data compression is disclosed. Live video signal data is vertically scaled. A 4:2:2 to 4:2:0 color format conversion is performed simultaneous with the vertical scaling step. A one-dimensional bufferless discrete cosine transform is performed on the scaled live video signal data to create a plurality of scaled DCT coefficients. Each of the plurality of scaled DCT coefficients are then Huffman coded. Each of the Huffman encoded DCT coefficients may then be sent via a USB interface to a USB bus.

摘要： Deinterlacing a video signal using a motion detector is disclosed. In one embodiment, a divider, a comparator, and an interpolator deinterlace a video signal and reduce combing artifacts. The divider forms a ratio of inter-field activity to intra-field activity in a video frame. The ratio is compared to an empirically determined threshold. If the ratio is greater than the threshold, then there is motion in the frame and the second field is interpolated from the first field. If the ratio is less than the threshold, then there is no motion in the frame and no change is made to the frame.

摘要： The invention provides an image processing apparatus and method as well as a providing medium by which deterioration of the vertical resolution is prevented and conspicuous appearance of line flickering is suppressed. In order to convert an interlaced video signal having 525 scanning lines into another progressive video signal having 525 scanning lines while maintaining the image size, in an odd-numbered field, a line after conversion is offset by 0.5 H (H is the distance between horizontal scanning lines of the inputted video signal). Consequently, pixel data of each line Oi are produced from pixel data of two lines Ii and Ii+1 before conversion. As a result, pixels of a line on the boundary between white pixels and black pixels have a gray color. In an odd-numbered field, no offset is given, and pixel data of each line I1 of the field before conversion are set as they are as pixel data of each line Oi of the field after conversion. The pixels of the line on the boundary between the white and black pixels become white or gray pixels, and consequently, when compared with an alternative case wherein such pixels on the boundary line are white and black pixels, line flickering is prevented from being observed conspicuously on a display screen.

摘要： An invalid frame in 60P images supplied from a 60P camera head is delayed by a single frame by a 1-frame delay circuit. A differential between the delayed invalid frame and the valid frame is computed by a subtracting circuit. Of the differential signal, only a portion over a predetermined value is picked out by a level filter. The picked out signal is attenuated to ½ by a ½ attenuator. By adding that attenuated signal to the valid frame by an adder, the invalid frame is superimposed on that valid frame. As a result, a natural picture is obtained.

摘要： A device for receiving, storing and displaying television images. The device comprises a buffer (2) for storing television images. Television images having a first frame frequency are received at an input (4). Television images having a second frame frequency are supplied at an output (6). The buffer is adapted to store and read television images. A number of X consecutive television images stored in the buffer lie between a television image read at a given instant from the buffer and a television image stored at substantially the same instant. In a first state, X increases with time. In a second state, X decreases with time. The device further comprises a control device (12) for generating a first control signal (14) for bringing the device from the first to the second state, and a second control signal (16) for bringing the device from the second to the first state. This device makes it possible to start to watch television images simultaneously at the instant of their reception, while television images received at a later instant and not yet displayed, for example, a block of commercials, can be watched in an accelerated manner.
