20080298779 | MOVING IMAGE COMMUNICATION DEVICE, SEMICONDUCTOR INTEGRATED CIRCUIT AND MOVING IMAGE COMMUNICATION METHOD USED FOR COMMUNICATION OF MOVING IMAGE - A transmitter transmits moving image data generated by an image generator to a communication line. A controller judges whether or not the moving image data can be transmitted based on communication status in the communication line. An image analyzer analyzes the moving image data and calculates an information volume thereof when it is judged by the controller that the transmission of the moving image data is not possible, and a storage memory stores the moving image data therein. A transmit image selector selects the moving image data to be read for transmission from all of the moving image data stored in the storage memory based on the information volume when a result of the judgment by the controller shows that non-transmittable status is changed to transmittable status and transmits the selected moving image data to the transmitter. | 12-04-2008 |
20080309803 | PHASE ADJUSTMENT DEVICE, PHASE ADJUSTMENT METHOD AND DIGITAL CAMERA - An intended-usage judger judges an intended usage of an inputted digital imaging signal. A selector selects one or a plurality of signals to be inspected from a group of signals constituting the digital imaging signal based on a result of the judgment by the intended-usage judger. A phase adjuster adjusts a phase of a pulse used when the digital imaging signal is picked up based on an output state of the signal to be inspected. | 12-18-2008 |
20080313683 | MOVING IMAGE COMMUNICATION DEVICE, MOVING IMAGE COMMUNICATION SYSTEM AND SEMICONDUCTOR INTEGRATED CIRCUIT USED FOR COMMUNICATION OF MOVING IMAGE - A communication processor sets a storage request signal to be effective when it is judged that a packet cannot be transmitted and sets the storage request signal to be ineffective when it is judged that the packet can be transmitted. A data processor makes a buffer memory store encoded data therein when it is confirmed that the storage request signal is effective. The data processor reads the encoded data from the buffer memory and transmits the read encoded data to a packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is stored in the buffer memory. The data processor receives the encoded data from the encoder and transmits the received encoded data to the packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is not stored in the buffer memory. | 12-18-2008 |
20090207253 | AUTOMATIC PHASE ADJUSTING APPARATUS - A digital imaging signal obtained by converting an image data obtained by an imaging element into a digital value for each pixel is inputted to an automatic phase adjusting apparatus, and the automatic phase adjusting apparatus adjusts phases of pulses to be used for imaging based on the inputted digital imaging signal. The automatic phase adjusting apparatus is provided with a brightness level detector for calculating a brightness level of the digital imaging signal for a plurality of pixels in a first pixel region, a variability calculator for calculating a variability value which indicates signal variability of the digital imaging signal for each pixel for a plurality of pixels in a second pixel region, and a timing adjuster for adjusting the phases of the pulses in accordance with calculation results obtained by the brightness level detector and the variability calculator. | 08-20-2009 |
20110141282 | INTERSECTION SITUATION RECOGNITION SYSTEM - An image pickup device that picks up an image of a direction not visible from a vehicle that is about to enter an intersection, and transmits the picked-up image to the vehicle is installed in the vicinity of a blind intersection. In addition, an in-vehicle device that receives the image from the image pickup device, and displays the image on a display device is mounted in the vehicle. The in-vehicle device retrieves an image pickup device identification number of an image pickup device installed at the intersection that the vehicle is about to enter and transmits the retrieved image pickup device identification number to the image pickup device and, only when an image pickup device identification number received from the image pickup device together with an intersection image and the retrieved image pickup device identification number match with each other, the in-vehicle device displays the received intersection image. | 06-16-2011 |
20110181744 | IMAGING APPARATUS AND METHOD FOR CONTROLLING IMAGE COMPRESSION RATIO OF THE SAME - When an input image is received from an imaging element, a detection circuit detects frequency information of the input image, and an electronic shake processing circuit detects shake information (motion amount) of the input image. A CPU receives the frequency information and the shake information via an image processing circuit. The CPU increases a compression ratio of the input image when high frequency components are dominant, and decreases the compression ratio when low frequency components are dominant. The CPU also increases the compression ratio when the input image is moving, and decreases the compression ratio when the input image is not moving. A compression/decompression circuit compresses the image based on the compression ratio thus set. | 07-28-2011 |
20110267452 | IMAGE COMPRESSING APPARATUS, IMAGE COMPRESSING METHOD AND VEHICLE-MOUNTED IMAGE RECORDING APPARATUS - A road shape recognition device checks a position of a currently travelling vehicle detected by a position detection device with map information so that a road shape at each travelling spot of the currently travelling vehicle is recognized. An image division device divides a display screen of surrounding image data of the currently travelling vehicle into a plurality of divided regions depending on the road shape and sets a data compression rate suitable for the road shape in each of the plurality of divided regions. An image compression device compresses the surrounding image data in each of the plurality of divided regions into codes based on the data compression rate set for each of the divided regions. | 11-03-2011 |
20110298942 | VIDEO IMAGE PICKUP DEVICE - An image processor detects an on-screen motion of a photographic subject in video image data generated by an image sensor provided in a camera body and outputs a photographic subject motion information. A sensor detects a motion of the camera body and outputs the detected motion as a camera body motion information. A scene decision encoding controller decides an image pickup condition of the video image data based on the photographic subject motion information and the camera body motion information, and performs an encoding amount regulation control suitable for the decided image pickup condition to an image compression processor. | 12-08-2011 |
20120321208 | IMAGE ENCODER AND CAMERA SYSTEM - A compression controller is capable of executing prediction mode selection for selecting any one of forward prediction, backward prediction, or bidirectional prediction as a prediction mode used for encoding based on spatial frequencies of an image to be encoded. The compression controller determines whether or not to execute the prediction mode selection based on image mobility information indicating an amount of motion in the image to be encoded. | 12-20-2012 |
