摘要:
A digital video signal recording and reproducing apparatus and method wherein a basic block is constituted by a plurality of pixels of video signals. A picture data compressing unit effects data compression of the video signals so that a compression data quantity after data compression becomes a constant with respect to a compression block constituted by a plurality of the basic blocks, and the compressed data o the video signals are recorded on a data recording medium. A compression block setting sets a number of the basic blocks to constitute the compression block in response to different operation modes of the digital video signal recording and reproducing apparatus which are different in at least one of resolution of the video signals, recording time and data compression system, and controls the picture data compressing unit so that the number of the compression blocks of the video signals recorded on one track of the data recording medium after data compression by the picture data compressing unit becomes M in a first operation mode, where M is a positive integer, and the number of the compression blocks becomes a positive integer in each of the other operation modes.

A cartridge includes: a liquid container adapted to contain a liquid; a filler port provided to fill the liquid into the liquid container; a supply port connected with a liquid supply tube provided in the printing device; a connection port provided to communicate with the liquid container; a liquid detection chamber adapted to vary volume according to inflow or non-inflow of the liquid through the connection port; a flow path arranged to connect the liquid detection chamber with the supply port; and a member provided to have the filler port, the supply port, the liquid detection chamber and the connection port arranged on one identical surface. The surface of the member has the supply port and the filler port arranged on one direction side relative to center of the surface, and the connection port arranged on an opposite direction side to the one direction side relative to the center. The liquid detection chamber is located between the connection port and the supply port.

In displaying image data received from a camera module on a display device such as a view finder, image data having a size suited for display from an image size conversion circuit is displayed via line memories included in a signal-for-display generation circuit. Vertical synchronization in an image data storage including these line memories is established by initializing a reading address in accordance with a frame head pixel indication and a reading completion indication of one line in the line memories. It is possible to reduce power consumption of an image display system for displaying an image of a imaging subject.

A video recording method used for a video recording apparatus which enables recording of both moving and still pictures on a recording medium, including: recording moving pictures encoded by a first encoding method, recording first still pictures encoded by a second encoding method which is different from the first encoding method, and recording second still pictures encoded by the first encoding method by which moving pictures are encoded, whereby a video reproducing apparatus enabled for decoding moving pictures encoded by the first encoding method, but which is not enabled for decoding still pictures encoded by the second encoding method, can decode the second still pictures recorded on the recording medium.
摘要:
Hot press forming of a steel material is made possible by coating the surface of the steel material with a plated layer of zinc or a zinc alloy and forming thereon a barrier layer which prevents the vaporization of zinc even when heated to 700-1000° C. Corrosion resistance can also be guaranteed without requiring post treatment, and hot press forming of high tensile steel sheet and stainless steel sheet is made possible. The barrier layer is formed by forming an upper plated layer, by surface oxidation, by contact with an oxidizing agent, by contact with Zn and an oxidizing agent, by anodic electrolysis, by cathodic electrolysis, or by coating with a ZnO sol.

An apparatus by which a user can easily set a parameter for conversion when a compression encoding system of video stream is converted is provided. A particular period in a first video stream is repeatedly reproduced to convert the reproduced portion into a second video stream in real time. At that time, the user checks the image quality after conversion on a preview screen and sets a desired conversion parameter. A local decode image is output to the preview screen. Thus, the circuit configuration is simplified.
