An image processing method and an image processing apparatus in which a DCT section transforms image data to a frequency conversion coefficient using a discrete cosine transform coefficient, a quantizing section quantizes the transformed frequency conversion coefficient using a quantization coefficient indicating weighing in quantization, a Huffman encoding section encodes the quantized data, and a CPU detects a code rate for encoded data by a prespecified time interval during execution of proce...

A real-time distortion analysis system (20) utilizes a baseline preparation processor (38) and a remote comparison processor (50) to determine (72, 78) a plurality of color and central moments for baseline and broadcast video streams respectively. The baseline stream is taken from a broadcast signal sent from a broadcast station (26), and the broadcast video stream is taken from a viewer signal sent from a remote receiving station (28, 30, 32) to viewers (34). The remote comparison processor (50...

An image of lower spatial resolution is converted into an image of higher spatial resolution efficiently and highly accurately. For such conversion, pixel data is ex-pressed by vectors in a color space of R, G, B, and not only an R component of low resolution but also R, G, B components are used to predict an R component of higher resolution.

An image processor includes spatial filters which execute parallel processing in units of component data of image data made up of a plurality of component data, and an original image color determination unit selects if input image data from a color image input unit is to be processed as a monochrome or color image. When it is selected that the input image data is to be processed as a monochrome image, the processing operations of the spatial filters for the image data are controlled to be execut...

A full color process image that can be printed with cyan, magenta, yellow, and black inks is produced as a duotone image using only two colors of ink. Color data defining the colors used in the full color image serve as input to a process that maps the colors into a duotone gamut defined by the two colors of ink that will be used to produce the duotone image. A user is able to select 0, 1, or 2 colors of ink for the duotone image, and the software program automatically chooses the remaining ink ...

In a person identification apparatus, a normalized face image is used to identify a person. When the face image of the person is input, a face area extraction section extracts the face area from the face image. A feature point extraction section extracts a plurality of candidates of feature points from the face area using a separation filter. A feature point set selection section selects sets of the candidates from the plurality of candidates of feature points according to face structure informa...

An apparatus for mounting an electronic part includes a reflector located in the rear of an electronic part held by a nozzle on a transferring head, and an image reading device for observing an electronic part held and moved by the transferring head. The image reading device picks up an image from the electronic part. The picked-up image is recognized so as to detect a position of the electronic part with which the motion of the transferring head is controlled. The image reading device includes ...

Image data decompression apparatus and method for receiving data words comprising a first sub-word and a second sub-word, at least some possible values of the first sub-word specifying a run of at least m instances of a predetermined data value, corresponding second sub-words specifying a number of instances of the predetermined data value in a range from at least m instances. The apparatus includes a first decoder for decoding the first sub-words to detect whether a current first sub-word speci...

A visual inspection system (10) and method for inspecting the operation of micromechanical devices. The system has a vision system (16), a vision system controller (18), a system controller (20), an illumination system (12), a digital signal processor and a mounting stage (22). The objects undergoing inspection, either wafers or devices, are mounted under the visions system. A probe card is engaged to the object and power is provided. The vision system (16) records which elements or devices on t...

An image forming apparatus including scanner section for reading an image of documents and an image of a separation sheet, a circuit for recognizing the image of the separation sheet from the image of the documents, a determining circuit for determining a processing for the image of the documents based on the image of the separation sheet, an operation panel for receiving a processing instruction for the image of the documents, and a processing circuit for processing the image of the documents b...
