An image processing module input/output port in a DMAC includes an input part which receives second address information and an addressing request signal from an image processing module and an output part which outputs a reply signal indicating valid reception of the second address information to the image processing module. The image processing module input/output port can perform signal input/output control processing of returning, in response to the addressing request signal, the reply signal indicating confirmation of valid reception of the second address information to the image processing module when valid reception of the second address information is confirmed. A memory access controller performs memory access processing of accessing a storage area to be accessed in a memory based on the first address information (=the second address information) received via the image processing module input/output port.

A format converter includes a first input buffer for storing input data, an output buffer for storing output data, a converter connected between the first input buffer and the output buffer, and a register that the converter refers to. The register allows plural kinds of conversion patterns to be defined in conformity with a desired data format conversion. The converter generates the output data based on the input data, in accordance with the conversion pattern defined in the register.

Data processor

An image processor includes an encoding unit encoding inputted data. The encoding unit includes a first processing unit splitting the data into a first partial data in a first digit range on an upper side and a second partial data in a second digit range on a lower side, a second processing unit encoding only the first partial data between the first partial data and the second partial data, and a third processing unit performing correction to set a value of the first partial data at '0'.

An image processor includes a quantization unit receiving first data before quantization and outputting second data after quantization, a prediction unit obtaining a difference value between the second data and third data being prediction data and outputting the difference value as fourth data, and an encoding unit encoding the fourth data. The quantization unit includes a first processing unit dividing the first data by a quantization coefficient, so as to obtain fifth data including a fraction as a result of division and a second processing unit rounding up or rounding off the fraction such that a value of the fourth data becomes smaller based on comparison between the third data and the fifth data, so as to obtain the second data.

The present invention provides an imaging unit, a portable terminal device, and a portable terminal system capable of performing a satisfactory key synthesizing process. An imaging unit mainly includes an imaging section, a conversion section, and a key signal generating section. The conversion section converts the format of the imaged image data output from the imaging section from YUV format to RGB format. The key signal generating section generates a key signal based on each pixel data configuring the imaged image data and the reference data for the imaged image data input from the imaging section. The key signal generating section also outputs foreground image data having the generated key signal and the corresponding pixel data of RGB format as minimum configuring unit. An image synthesizing section of a main unit generates synthesized image data by overlapping the foreground image data from the imaging unit and the background image data stored in a RAM based on the key signal contained in the foreground image data.

A rod lens manufacturing method having satisfactory machining accuracy and enabling mass production. In the method, lens assembly sheets, each holding at least a row of rod lenses, are prepared. The lens assembly sheets are then arranged on holding surfaces defined on a jig. The holding surfaces are inclined relative to a reference surface of the jig by a predetermined angle. Each of the lens assembly sheet is clamped so that optical axes of the rod lenses are inclined relative to a direction perpendicular to the reference surface by that predetermined angle. The lens assembly sheets are then ground and polished.
