A data output section (13d) outputs the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region. A display mode setting section (13c) performs setting of the display mode. In accordance with switching of the selected region, a control section (13e) changes a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

An object incorporated in image data is formed with a plurality of polygons. An object table defines each polygon by means of coordinates at an apex in a view coordinate system and the sound generated from the polygon. The sound source processor unit controls sound to be generated from each polygon according to the position and direction of the polygon when the object is viewed from a viewpoint.

A video display control system displays a multicolor animation pattern on a screen of a video display unit. The video display control system is mainly constructed by a video RAM (VRAM) and a video display processor (VDP). The VRAM stores animation pattern data, display position data and at least two color data. The VDP reads these data and makes an animation pattern image displayed in at least two colors at a display position on the screen. The animation pattern image, two colors and display position are determined by the animation pattern data, two color data and display position data. In another video display control system, the VRAM stores at least two sets of animation pattern data, display position data and color data. When displaying two animation patterns, the VDP effects a logical operation on the two color data with respect to the overlapping portion of the two patterns and makes the overlapping portion displayed in a new color corresponding to the operation result. When the animation patterns overlaps, the VDP can also deliver a collision signal in place of the logical operation, thereby enabling a CPU to recognize the position of the overlapping portion.

An electronic circuit with an operation self-control function includes an electronic circuit body. A temperature sensor and a temperature-setting circuit detect the temperature of the electronic circuit body as an operating parameter indicative of an operating condition of the electronic circuit body, and a clock/peripheral circuit control circuit operates to restrict the operation of the electronic circuit body according to the detected temperature, to thereby restrain heat generation of the electronic circuit body.

An image processing apparatus processes image data stored in a memory to thereby display an image on a display screen of a display unit under a control of a central processing unit (CPU). In one aspect of the invention, source data read from a source area of the memory are subjected to a rotation process and a logical operation and then converted to transfer data which will be written in a destination area of the memory by every word. In addition, first and last words within one line on the display screen are masked in accordance with predetermined first and second mask data. In another aspect of the invention, one of a wait mode and a not-wait mode is selected by wait control data outputted from the CPU. In the wait mode, the CPU is subjected to a wait state even in a memory read cycle. In the not-wait mode, the CPU is not subjected to the wait state normally in the memory read cycle. However, the CPU is subjected to the wait state in the not-wait mode while a reading operation of the memory has not been completed.

A video display processor (VDP) produces a video signal by which a black and white image of an increased gradation can be displayed on a video display unit. The VDP reads from a video RAM (VRAM) either color codes each representative of a color of each display element, or amplitude data representative of amplitudes of a video signal to be reproduced. When displaying an image based on the color codes, the color codes are converted by a color palette circuit into color data each composed of three primary color data, and then supplied to a digital color encoder. The digital color encoder multiplies each of the three color data by predetermined coefficients at proper phase timings to output data representative of three chrominance signals. This output data is summed by an adder circuit and then converted into an analog signal to be supplied to the video display unit as the video signal. When displaying an image based on the amplitude data, the color palette circuit converts the amplitude data into gradation data. The digital color encoder multiplies the gradation data by other proper coefficients so that data proportional in value to the gradation data are obtained at the output of the adder circuit. This data is converted into an analog signal to thereby reproduce the video signal.
摘要:
A video display control system comprises a video display processor (VDP) which is capable of accessing to a video RAM (VRAM) at an extremely high-speed. The VRAM used in this system comprises first and second dynamic RAMs each having an address input terminal to which row address data and column address data are supplied, a row address strobe input terminal, a column address strobe input terminal, and a data input/output terminal. The row address data is latched at the leading edge of a row address strobe signal applied to the row address strobe input terminal, while the column address data is latched at the leading edge of a column address strobe signal applied to the column address strobe input terminal. An access to an address of each dynamic RAM is established when both of the row and column address data are latched. The VDP comprises a VRAM interface for controlling an access to the first and second dynamic RAMs which is connected to the RAMs through a common address bus. The VRAM interface first outputs row address data together with a row address strobe signal RAS and then outputs column address data together with two column address strobe signals CAS0 and CAS1 which are rendered active in sequence and supplied to the first and second dynamic RAMs, respectively.

In an image processing apparatus that processes image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, a region selection mode setting section (13b) selectively sets a first region selection mode in which, from a field of view represented by the image data, a selected region is selected which indicates a partial region of the field of view by using an orthogonal coordinate system and a second region selection mode in which, from the field of view represented by the image data, the selected region is selected which indicates the partial region of the field of view by using a polar coordinate system. A distortion correction section (13a) corrects the distortion contained in the image data that corresponds to the selected region selected the first or second region selection mode selected in the region selection mode setting section (13b). A data output section (13d) outputs distortion-corrected data.
摘要:
An image processing apparatus sequentially reads image data corresponding to an area to be displayed from an image memory by use of an access address. This image memory stores the image data corresponding to the display area and other image data for other uses. The access address for the image memory is determined by the image processing apparatus such that the access address is increased from the predetermined start address in response to a scanning of a display screen. When the access address reaches at a predetermined boundary address representative of an address of the last image data corresponding to the display area of the image memory, the access address jumps to a predetermined jump destination address (such as the start address). Hence, the display will be started from the jump destination address, whereby the other image data can be prevented from being used for the display or from being destructed.
