摘要： Encoding processes are performed in their respective encoding modes until their respective quantized DCT (discrete cosine transform) coefficients are generated. Based on information about code amounts generated in the encoding modes, an encoding mode that provides a smallest code amount is determined. DCT coefficients corresponding to the determined encoding mode are subjected to variable-length encoding.

摘要： In the image encoding apparatus, the bus traffic monitoring unit monitors the traffic of the memory bus and when the memory bus is congested, the prediction selector is instructed to select the output from the DC prediction unit. Conversely, when the memory bus is not congested, the prediction selector is instructed to select the output from the AC prediction unit. The memory unit stores therein DC coefficients and AC coefficients outputted from the DCT unit so that AC prediction encoding can be performed.

摘要： A VLC mode judgment section performs judgment on whether or not a received group (Last, Run, Level) exists in a VLC table and then performs judgment on which one of a first escape mode, a second escape more and a third escape mode is suitable. According to a judgment result of the VLC mode judgment section, an FLC processing section or a coding mode selection section performs variable-length coding using selected one of the received group (Last, Run, Level), a group generated in the first escape mode, and a group generated by the second escape group or fixed-length coding using a third escape mode.

摘要： A robot includes a body structure on which a robot arm having an end effector is rotatably supported. The body structure has a stationary base unit fixedly installed and a movable unit rotatably supported on the stationary base unit to turn about an axis of rotation. The stationary base unit includes a stationary-side guide part having a stationary-side internal space in which a flexible, elongate member connected to the robot arm or the end effector is extended loosely along the axis of rotation. The stationary-side guide part opens upstream in an elongate member inserting direction. The movable unit includes a movable-side guide part having a movable-side internal space in which the elongate member is extended loosely along the axis of rotation. The movable-side guide part opens downstream in an elongate member inserting direction. The stationary-side and the movable-side internal spaces communicate with each other.

摘要： Compressed image data from a code memory is separated into quantization step values, code table information and variable-length codes. The variable-length codes are each decoded into a run length, a size and an additional bit string and written into a size memory. A size conversion section converts the run length, the size and the additional bit string from the size memory based on a frequency region and a size conversion amount set in a size conversion table. A variable-length code is assigned to each converted run length/size combination, and an additional bit string is attached thereto, thereby producing a variable-length code. The variable-length codes, the quantization step values and the code table information are multiplexed together to produce compressed image data.

摘要： The code amount in first video data is counted. The difference between the counted code amount and a predetermined code amount is summed. A target code amount for second video data to be encoded after the first video data is corrected based on the accumulated sum. An evaluation function for the second video data is selected based on the calculation of the motion vector of the second video data. The process calculates a first value based on a first quantization parameter for the first video data, the selected evaluation function and the counted code amount, and a second value based on a second quantization parameter for the second video data, the selected evaluation function and the corrected target code amount, and determines the second quantization parameter so that a difference between the first value and the second value is less than or equal to a predetermined amount.
