According to one embodiment, a plurality of moving objects is detected from a plurality of frames acquired in time series. The memory may be configured for storing data buffered by the cache. 50 \u212b; a bulk silica to alumina ratio in the range of from 5 to 10; and an alkali metal content of less than 0. Furthermore, the zoom circuit for recording performs a zoom process using spline interpolation or linear interpolation on image data from the YUV conversion circuit so as to create recording image data. The operator operates an input portion 2 on the basis of the contents displayed in the display 7 to correct the generated model transforming data.
