A copper alloy powder is a copper alloy powder for additive manufacturing. The copper alloy powder contains more than 1.00 mass % and not more than 2.80 mass % of chromium, and a balance of copper. A method for producing an additively-manufactured article includes a first step of preparing a copper alloy powder containing more than 1.00 mass % and not more than 2.80 mass % of chromium and a balance of copper and a second step of producing the additively-manufactured article from the copper alloy powder, and the additively-manufactured article is produced such that forming a powder layer including the copper alloy powder, and solidifying the copper alloy powder at a predetermined position in the powder layer to form a shaped layer are sequentially repeated to stack such shaped layers to thus produce the additively-manufactured article.

In an earliest vertical synchronization period after sending an encoded image data is restarted, a first reference image determination circuit determines to employ a local decoded image generated in a vertical synchronization period immediately preceding a vertical synchronization period in which an error occurs among multiple local decoded images stored in a first DRAM as a reference image. In an earliest vertical synchronization period after a decoding circuit is reset, a second reference image determination circuit determines to employ a decoded image generated in the vertical synchronization period immediately preceding the vertical synchronization period in which the error occurs among multiple decoded images stored in a second DRAM as a reference image.

A compressed data generator compresses, by using a lossless compressor and a lossy compressor, image data in units of first blocks to generate a plurality of types of compressed data. A selector performs selection processing in units of second blocks each including a predetermined number N of first blocks, where N is an integer of 1 or more. The selection processing involves determining whether each of the plurality of types of compressed data satisfies a selection condition and selecting one piece of compressed data that satisfies the selection condition. The selection condition includes a data size condition that a data size of all the first blocks included in the second block is less than or equal to a predetermined value, and a data accuracy condition that information maintaining accuracy is highest among compressed data that satisfy the data size condition.

A moving image coding apparatus performs efficient moving image compression on video with much noise (with a poor S/N ratio), and enables appropriate bit rate control (code amount control). A first orthogonal transform unit performs orthogonal transform of an input moving image. A complexity obtaining unit obtains a complexity of the input moving image based on frequency component data obtained through orthogonal transform by the first orthogonal transform unit. A noise determination unit determines noise in the input moving image based on the frequency component data obtained through orthogonal transform by the first orthogonal transform unit. A code amount adjustment unit generates a code amount adjustment signal based on the complexity obtained by the complexity obtaining unit and the noise determination result obtained by the noise determination unit. A coding unit subjects the input moving image to a coding process including quantization using a quantization parameter value determined based on the code amount adjustment signal generated by the code amount adjustment unit.

The codec processor includes an SRAM that holds a reference image read from an image storage, and a motion search unit that performs motion search on the basis of a reference image held in the SRAM to generate a prediction block for a target block in an input image. The SRAM holds a reference image having a horizontally equivalent number of pixels to a horizontal number of pixels of the input image and a number of pixels vertically larger than or equal to a vertical motion search range.

Moving images are coded with reduced deterioration in the image quality while variations in the amount of code per frame are being reduced. A moving image coding apparatus includes a remaining picture number obtaining unit, an activity calculation unit, an intra MB determination unit, and a coding unit. The remaining picture number obtaining unit detects the temporal position of the current frame image, and determines the reset timing at which an intra refresh process is reset in a manner that the reset timing differs for each macroblock line (MBL). The activity calculation unit calculates an activity value for each macroblock (MB). The intra MB determination unit determines a MB to be set as an intra MB based on the activity value calculated by the activity calculation unit. The coding unit codes the MB set as an intra MB through an intra coding process.
