    摘要： An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. The image capturing apparatus includes an image sensor for capturing an image of the object by receiving reflected light, distance-measuring light-emitting devices for irradiating the object with spot light, and a control circuit for driving the distance-measuring light-emitting devices, detecting the spot light positions of the distance-measuring light-emitting devices from an image captured by the image sensor, and obtaining the distance to the object. The image sensor provided for capturing an image of the object can be used as a photodetector device for distance measurement. With this, it becomes unnecessary to separately provide a photodetector device for distance measurement, which enables miniaturization of the image capturing apparatus, as well as cost reduction.

    摘要： A printer control apparatus provided with a CPU for converting video data supplied from an external unit to video data tailored to the operation of the printer; a memory holding various types of data during that conversion processing; and a read/write control unit performing the read/write control of the data between the memory, CPU, and the printer, which includes latch units which respectively latch the address and data from the CPU and thereby perform the processing at the minimum bus cycle. Also, the upper bit side of that address is made to include the control data from the CPU, and an autonomous read/write control is carried out. Further, that read/write control is carried out while using the video buffer comprising several standard size pages and by freely using that page.
