Abstract:
An image processing apparatus includes an object extracting unit, a selecting unit, and an object storing unit. The object extracting unit extracts an object from a target image through a plurality of processing, and outputs the result of extracting the object. The selecting unit selects at least a part of the result of extracting the object which is obtained through the plurality of processing, in accordance with a user's operation. The object storing means stores the result of extracting the object which is selected by the selecting unit.
Abstract:
On the transmission side, a background picture and objects #1 to #3 are transmitted at a transmission rate R/4 each. On the reception side, a picture composed of the objects #1 to #3 and the background picture is displayed with a particular spatial resolution and a particular temporal resolution. In this case, on the reception side, when the object #1 is dragged at particular time t1, on the transmission side, as shown in FIG. 16 (A), the transmission of the background picture and the objects #2 and #3 is stopped. Only the object #1 is transmitted at the transmission rate R of the transmission path. Thus, a picture of which the spatial resolution of the object #1 dragged is improved is displayed at the sacrifice of the temporal resolution of the picture.
Abstract:
The present invention provides an image processing apparatus and method destined for processing image data sent via a communication system. In the apparatus and method, image data corresponding to designation data supplied from the user are coupled to each other for grouping, features of the image data corresponding to the designation data, and the image data once coupled together as in the above are uncoupled according to the features of the grouped image data, to thereby accurately localize an area the user is interested in. Also, according to the present invention, a time interval between the designation data is computed, and the image data are coupled to each other when the computed time interval is less than a predetermined threshold, while they are not coupled to each other when the computed time interval exceeds the predetermined threshold, thereby detecting when the user's interest shifts to another image area. With this detection of the shift of the user's interest, it is possible to accurately localize an area the user is interested in.
Abstract:
In a sound-source signal separating method, a target sound-source signal in an input audio signal is enhanced, the input audio signal being from a mixture of acoustic signals from a plurality of sound sources picked up by a plurality of sound pickup devices. The pitch of the target sound-source signal in the input audio signal is detected, and the target sound-source signal is separated from the input audio signal based on the detected pitch and the enhanced sound-source signal.
Abstract:
In order to easily generate a control signal when a motion in accordance with an image is applied to a chair for an observer, a motion vector is detected from an image signal input to an image processing apparatus by a feature information detection section. By using the motion vector, a horizontal component, a vertical component, a magnification component, and a rotation component are determined. A feature information processing section generates a control signal to be supplied to a driving section from these determined components.
Abstract:
In an image processing apparatus, an input image is synthesized with a stored image supplied from a storage unit and having been shifted so that the positions of the pixels in the image areas of the input image and of the stored image, associated with a telop, will coincide. The level distribution of the pixel values of the input image is maintained in the telop.
Abstract:
A multi-sensor camera compares status describing data which is described based on a determining rule and sensor data outputted from a microwave sensor with a notification determining table sent from a processing box. If it is determined that an event is notified, the multi-sensor camera sends notifying image data to the processing box, and presents the sent data on a presenting unit. A user inputs, based on a predetermined detecting condition, the determination on the notification need of the event detected based on the sensor data outputted from the sensor. A unit for learning the determining rule adjusts the predetermined condition used for the detection based on the input determination and the feature of the event, and updates the notification determining table so as to notify the event which needs the notification and prevent the notification of unnecessary event.
Abstract:
A luminance signal Ya and a color-difference signal Ua/Va constituting an input image signal is transferred to a frame memory (first memory) in the unit of line synchronously with its horizontal synchronous signal and written therein. A memory TG211 reads out a read-out request RRQ. The cycle of this request RRQ is a time computed based on a single vertical effective period of an output image signal Sc and the number of lines objective for rate conversion of an input image signal Sa. The luminance signal Ya and color-difference signal Ua/Va are transferred in the unit of line from the frame memory to rate conversion units (second memory) through buffers. There occurs no deflection in this transfer cycle and in each transfer cycle, the stable data transmission band can be secured.
Abstract:
The present invention relates to a data conversion apparatus and a learning device in which an image can be converted into a higher-quality image. A class-tap generating circuit (2) and a predictive-tap generating circuit (3) generate, from an SD image, a predictive tap used for determining the HD pixel of a specified block of an HD image. A classification circuit (4) classifies the HD pixel of the specified block based on the class tap. A coefficient RAM (7) obtains a tap coefficient for the class of the HD pixel of the specified block from tap coefficients obtained by learning the relationship between supervisor data and learner data for each class of at least one class by giving a predetermined constraint condition to the supervisor data. A predictive-computation circuit (8) and a decoding circuit (9) determine the HD pixel of the specified block by using the tap coefficient and the predictive tap.
Abstract:
An IC chip allows first communication for performing communication with all of the other IC chips, and second communication for performing communication while restricting communication parties. That is to say, the IC chip performs sending/receiving signals with a new communication arrangement with both the first communication which is a broadcasting arrangement and the second communication which is a communicatory arrangement. This enables the function upgrading electronic equipment to be performed easily, and enables flexible signal processing with a new communication arrangement.
