Abstract: In a data recording and reproducing apparatus which records and reproduces a record medium in which at least two kinds of data having different data types can be recorded, data is read out from the record medium, and a digital watermark is detected from the data read out. The kind of data is determined depending upon whether the digital watermark is detected, and it is determined whether retry processing at the time of reading-out the data and verifying processing at the time of writing should be executed. The retry processing or the verifying processing is executed only for the data which is determined that the retry processing or the verifying processing should be executed. Therefore, in the case of data whose reading-out continuity is more important than reliability, the retry processing is omitted, so that time required for reading-out processing can be shortened.

Abstract: When a user instructs acceleration or deceleration of the CPU processing speed with an “accelerator” button or a “brake” button, a speed control MMI informs power management system software of the corresponding information to change the CPU processing speed. The change is recorded on a speed management database in correspondence with the name of the application program which is currently being executed. Every time acceleration or deceleration of the CPU processing speed is instructed by the user, speed management data is formed on the speed management database. By using the speed management data, the CPU processing speed can be dynamically controlled for each piece of software when it is executed. Further disclosed is a novel power dissipation control system for a microprocessor, adapted to be used in conjunction with the above described MMI.

Abstract: An apparatus for generating a high-quality character pattern defined by edge lines includes a code pattern memory, a projection section, a filling section, and a controller. The code pattern memory is divided into a plurality of areas and stores winding number (WN) code data corresponding to a plurality of characters. The projection section, in response to an input projection start command, projects input size-changed edge lines defining a pattern in the code pattern memory in units of N points (N is a positive integer of 2 or more) continuous in a line direction perpendicular to a filling direction while the WN codes of points corresponding to the plurality of characters stored in the divided areas of the code pattern memory are updated by a WN code determined at each point. The projection section also generates a projection end response when projection of the size-changed edge lines is completed.

Abstract: Translation handles are set on vertices of a conversion source image frame by a mouse. Frame move processing, enlargement/reduction processing, rotation processing, and deforming processing are performed in accordance with the number and positions of the set translation handles. The image within the frame is operated in accordance with the shape of the conversion source image frame, and the operated image is displayed within the conversion destination image frame. In geometric conversion which requires enlargement/reduction and rotation and preserves parallelism of lines, image conversion is performed by one processing including addition instructions and not including multiplication and division calculations.

Abstract: In processing of a minimizer average error method (or an error diffusion method), a threshold value for determining whether a point (pixel) as an object to be processed is a black or white dot is changed in accordance with the pixel position using a threshold value matrix having a two-dimensional repetitive pattern. When a one-dot size in an output apparatus which can only perform binary expression in units of pixels is larger than a logical size, a continuous tone image is converted into a pseudo half tone image in consideration of an increase in size of a dot into other dots (projecting portions).
