A sensing baseball game apparatus () has a game machine () connected to a television monitor (). A bat input device () is provided with an acceleration sensor. An acceleration signal is transmitted by an infrared-ray LED () to an infrared-ray receiving part of the game machine () whereby the game machine () determines a moving speed of the bat input device () to calculate a moving parameter of a ball to be batted. Accordingly, a batted ball is moved in the game scene according to the parameter.

A CMOS image sensoroutputs a differential signal (VF&#x2212;VU) between a pixel signal (VF) in a period when a LEDis turned on in an exposure period and a pixel signal (VU) in a period when the LEDis turned off in the exposure period. This does not obtain a difference between a pixel signal in an exposure period and a pixel signal in a non-exposure period. It is possible to increase simplicity in utilization as well as suppressing fixed pattern noise by generating the difference between pixel signals in different exposure spans from each other.

Image sensor and image sensor system

A card game apparatusincludes an image sensor. The image sensor photographs a design (: FIG.) printed on a card. A photographic signal from the image sensor is sampled by a game processor, and is further re-sampled to form a photographic pixel data array. A ROMis provided with a database (A: FIG.) which is assigned a comparison data array and a card ID for each entry. By searching the database based on the photographic pixel data array, the processorobtains one card ID and displays card data of the card identified by the card ID on a television monitor.

An effective bus arbitration unit is described in which it is possible to reduce, as much as possible, the waiting time until a bus master obtain bus ownership and improve the rate of operating the bus while improving the throughput of data transfer. A bus master issues a size signal (for example, signal 'CDSZ') indicative of the size of data to be read or written. A state machinegrants bus ownership to the bus master for the bus cycles corresponding to the size signal in order to enable the bus master to successively read or write data. Arbitration is performed once for every series of bus cycles corresponding to the size requested by the bus master. Since the size signal is issued by the bus master as a size signal indicative of the necessary and sufficient size for data transmission, the state machinecan set an optimal number of bus cycles.

A method of detecting an image of a reflective object includes the steps of capturing an exposure image by an image sensor while an LED is ON; down-sampling an exposure image signal from the image sensor to a first digital signal by comparing the level of the first image signal with a first reference level; capturing a dark image by the image sensor while the LED is OFF; down-sampling a second image signal from the image sensor to a second digital signal by comparing the level of the second image signal with a second reference level; computing an image of difference between the exposure image and the dark image by subtracting the second digital signal from the first digital signal; and specifying the image of the reflective object by locating a bright point remaining in the image of difference.

A sound processor is formed on a single semiconductor device and has a function as a bus master for a common bus to positively and effectively access a resource on a common bus. Outputted is data over N sets (N being a natural number greater than 2) of sound channels through time division multiplexing to M sets (M being a natural number) of independent digital/analog converting means for converting sound-channel digital data into an analog sound signal. This reproduces pulse-code-modulated sound waveform data capable of simultaneously reproducing over a plurality of sets of sound channels represented by a product of M and N.

An information processing apparatus includes man-machine interface, a semiconductor memory and an information processor. The semiconductor memory is configured by an application software contents portion, an application software engine, an operating system, an information processor hardware driver and a man-machine interface driver. Clear definition is given to interfaces between modules including software and hardware.

An information processing apparatus includes a high-speed processor, and the high-speed processor processes a game program restored in a memory cartridge. A power control routine is then executed, and capacitors (C, C) included in a charge pump circuit is repeatedly charged and discharged. If an error occurs in the high-speed processor and then the power control routine is not properly executed, a difference in electric potential (V) between one end of a resistor (R) and a reference electric potential surface or point increases. When the difference in electric potential exceeds a threshold value, a supply of stabilized voltage is stopped by a power on/off control circuit, and an entire system including the high-speed processor is then turned off.

A musical scale recognition apparatus includes an analog/digital converter and a processor, and can determine by the processor how close an input analog audio signal is to a musical scale of a musical tone to be recognized by repeatedly performing a calculation of a cumulative value As to find a coefficient of a Fourier sine series of the audio signal on the basis of a frequency f and digital data D, a cumulative value Ac to find a coefficient of a Fourier cosine series of the audio signal on the basis of the frequency f and the digital data D, and a frequency power spectrum effective value A of the audio signal on the basis of the cumulative value As and the cumulative value Ac, wherein the digital data into which the input analog audio signal is converted by the analog/digital converter is D, the frequency (musical scale) of the musical tone to be recognized is f, and a current time is t. At this time, A is a value which shows how close the input audio signal is to the musical sound to be recognized, and it is shown that the larger the value A becomes, the closer the both sides are.
