Abstract: Some examples may relate to an object-recognition system. The object-recognition system may generate an object identifier when an object having detectable elements in a predetermined spatial pattern is in proximity to a capacitive sensor. The object-recognition system may include a capacitive sensor and a reader to capture channel-capacitance measurements at least partially responsive to the capacitive sensor in proximity of the detectable elements. The object-recognition system may include a recognizer to generate an object identifier at least partially responsive the captured channel-capacitance measurements.

Abstract: A passive-matrix display device has rows (2) of pixels (Pij). A row driver (8) selects sub-groups of the rows (2) to obtain multiple row addressing. Each sub-group has a particular number (p) of the rows (2). In each frame period (Tf) the sub-groups are selected a number of times equal to the particular number (p) at different select instants (ti). The multiple row addressing is based on a scheme defined by a function matrix (FM) which has orthogonal functions (Fi(t)). The columns of the function matrix (FM) represent the orthogonal functions (Fi(t)) at the select instants (ti). The function matrix (FM) is changed such that each one of the columns has at least two non-zero elements (?1,1) and at least one zero element (0).

Abstract: A generic apparatus (14) re-orders video data for various types of displays, such as plasma discharge panels (PDPs), digital micro-mirror devices (DMDs), liquid crystal on silicon (LCOS) devices, and transpose scan cathode ray tube (CRT) displays. In one embodiment, the apparatus (14) includes a first programmable transpose processor (18), a memory (20, 120), and a second programmable transpose processor (22, 122) fabricated as a single IC unit.

Abstract: A table-based driving circuit for displays that switches between a normal operational mode and a read table block mode. The driving circuit comprises an address sequencer and a memory. The memory comprises the full table of individual sequences, such as interlacing or color-sequential sequence. In the read table mode, the next upcoming addresses are read, i.e. are downloaded, from the memory into an address table register in the address sequencer. In the normal operational mode, the address sequencer generates the addresses for the video data to be stored in the memory or to be displayed.

Abstract: In a motion vector estimation method, a block-based motion vector estimation process (BME) that involves comparing a plurality of candidate vectors is carried out to determine block-based motion vectors, at least a most frequently occurring block-based motion vector (MFMV) is determined, a global motion vector estimation process (GME) using at least the most frequently occurring block-based motion vector (MFMV) is carried out to obtain a global motion vector (GMV), and the global motion vector (GMV) is applied as a candidate vector to the block-based motion vector estimation process (BME).

Abstract: This invention relates to a method for improving the perceived resolution of a colour matrix display with at least one pixel, comprising the steps of subdividing an incident colour channel signal (R) to said pixel into a first and second signal component (R1, R2), applying a gain factor (CR) to one of said signal components (R1, R2), and-subsequently recombining said first and second signal components (R1, R2) into an exiting, modified colour channel signal (R?).

Abstract: The invention relates to a video circuit (1) for processing video signals which show images on a display panel with linear light transition, comprising a gamma correction circuit (3), a quantizer (11) and a sub-field generator circuit (8). To save computing time, a random-access memory (7) replaces the quantizer (64).

Abstract: The invention concerns a device and method for converting and supplying a display driving unit with luminance values as well as a portable electronic device and a display unit including the converting device. The device includes an input (33, 35, 37), which receives a first value representing a luminance level with a first word length. It also includes a conversion unit (34, 36 38), that converts the first value into second and third values. These values together represent the luminance level represented by the first value and have a second word length. The second word length is shorter than the first word length. The device also includes a subfield control unit (32), which supplies the second and third values to the display driving unit during a frame period of the display. The time taken up by each converted value is a subfield of the frame. The subfield of the third value is longer than the subfield of the second value.

Abstract: An advanced video compression coding system which employs variable block size transforms to improve the compression efficiency for transmission of video pictures. A picture block segmentation map is transmitted as a one-dimensional series of block-size codes by scanning the segmentation map in accordance with a predetermined scanning pattern and on the basis of block size. A block-size code is skipped when the scanning pattern intersects a block which has already been scanned earlier. The series of block-size codes is then run-length and Huffman-coded before being transmitted.

Abstract: Device for splitting an interlaced television frame into a vertical low-frequency spatial signal and a vertical high-frequency motion auxiliary signal. In a forward play mode the two signals are added together. In a reverse play mode, in which the frames are supplied in the reverse order, the motion auxiliary signal is subtracted from the spatial signal.

Abstract: Device for splitting a digital interlaced television signal into components in which interlaced frames are applied to a vertical low-pass filter (6). To prevent motion artefacts in the spatial signal thus obtained, the interlaced frame is also applied to a vertical high-pass filter (8). This vertical high-pass filter supplies a motion auxiliary signal which may have a small vertical bandwidth. When combining the spatial signal and the motion auxiliary signal, noticeable motion artefacts do not occur in the interlaced frame. The device may be used for deriving a standard television signal from a high-definition television (HDTV) signal and for compatible transmission of HDTV signals.
