Abstract: A communication terminal with a camera includes a communicator for processing the sending and receiving of mail messages, a designator for designating any one of the mail messages received by the communicator as a browsing mail message, and a determiner for determining whether there is an image related to the browsing mail message. When a determination result by the determiner is negative, a first validator validates a defined camera setting, and when a determination result by the determiner is affirmative, a second validator validates a camera setting compliant with the related image. A creator creates an image along with the camera setting validated by the first validator or the second validator, and an attacher attaches the image created by the creator to a mail message using a sending source of the browsing mail message as a destination.

Abstract: In a case of recording data into an optical disk (100), a disk apparatus (10) rotates the optical disk (100) by a ZCLV system, and in a case of reading out the data from the optical disk, the disk apparatus rotates the optical disk by a ZCAV system. By rotating the optical disk by the ZCLV system, a DSP (28) performs a read of a modified read carried out before recording, and a read of a verification carried out after the recording, and thereby, no occurrence of a change of a rotating speed of the optical disk among the modified read, the recording, and the verification.

Abstract: A disk apparatus (10) includes an optical pick-up (12) and a DSP (28), and irradiates a laser beam onto a recording surface of a disk recording medium (100) by the optical pick-up. In a case that a time period (access time period) required for a seek is shorter than a time period (changing time period) required for the number of rotations, the DSP does not simultaneously perform a change of the number of rotations and the seek. To the contrary, the DSP delays the seek by |access time period?changing time period|, and performs a recording and a reproduction after the change of the number of rotation is ended.

Abstract: An electronic camera includes a camera unit. In photographing an object continuously in a predetermined cycle by means of the camera unit, a main CPU controls a strobe control circuit to change combinations of transistors T1, T2 and T3 to be turned on/off in synchronization with the cycle of photography. As a result, the magnitudes of currents passing through a plurality of LEDs foming a strobe are changed, and thus the amount of light emitted from the strobe varies in synchronization with the cycle of photography.

Abstract: A disk apparatus includes a DSP (Digital Signal Processor), and the DSP performs a test writing and a test reading on a magneto-optical disk rotated in a ZCLV system to obtain an optimal reproduction laser power value (reference reproduction laser power value) “Pt” at a linear velocity of 30 Mbps in the ZCLV system. Next, by use of a relational expression between a power coefficient and a linear velocity, a linear velocity coefficient “?x” as an optimal reproduction laser power value at a desired linear velocity (zone) “Vx” in a ZCAV system is obtained when the reference reproduction laser power value is multiplied. Then, the optimal reproduction laser power value at the zone in the ZCAV system is obtained by multiplying the reference reproduction laser power value “Pt” by the linear velocity coefficient “?x”.
