Abstract

An electronic apparatus having an acceleration sensor for detecting acceleration occurring in the electronic apparatus, a housing for housing the acceleration sensor, a jolt detector housed in the housing and detecting whether or not the housing is jolted based on the detection result of the acceleration sensor, a processor for processing relating to content data, and a controller for controlling the processor when a jolt of the housing is detected by the jolt detector.

Claims

1. An electronic apparatus comprising:

an acceleration sensor for detecting acceleration occurring in said electronic apparatus,

a housing for housing said acceleration sensor,

a jolt detecting means housed in said housing and detecting whether or not said housing is jolted based on the detection result of said acceleration sensor,

a processing means for processing relating to content data, and

a control means for controlling said processing means when a jolt of said housing is detected by said jolt detecting means.

2. An electronic apparatus as set forth in claim 1, wherein

a storage medium,

a head for accessing said storage medium, and

a drop detecting means for detecting dropping of said electronic apparatus based on detection results of said acceleration sensor are provided in said housing;

said processing means processes said content data which said head reads from said storage medium; and

said control means moves said head to a predetermined retraction position when said drop detecting means detects dropping of said electronic apparatus.

3. An electronic apparatus as set forth in claim 1, wherein

said acceleration sensor generates a detection signal in accordance with acceleration in a direction substantially perpendicular to a predetermined surface among a plurality of surfaces forming said housing, and

said control means controls said processing means when said jolt detecting means detects a pulse in said detection signal generated by said acceleration sensor.

4. An electronic apparatus as set forth in claim 3, wherein said control means controls said processing means when said jolt detecting means detects continuous change in any of said X-, Y-, and Z-detection signals, then detects the generation of said pulse in said Z-detection signal, then detects continuous change in any of said X-, Y-, and Z-detection signals.

5. An electronic apparatus as set forth in claim 3, wherein said control means controls said processing means when said jolt detecting means does not detect a change in any of said X-, Y-, and Z-detection signals, then, in that state, detects the generation of said pulse in said Z-detection signal, then does not detect a change in any of said X-, Y-, and Z-detection signals.

6. An electronic apparatus as set forth in claim 3, wherein

said acceleration sensor generating a Z-detection signal indicating acceleration in a Z-direction constituting said perpendicular direction and an X-detection signal and Y-detection signal indicating accelerations in mutual perpendicular X- and Y-directions perpendicular to said Z-direction, and

said control means does not control said processing means when said jolt detecting means detects continuous change in any of said X-, Y-, and Z-detection signals, then detects the generation of said pulse in said Z-detection signal, then does not detect a change in any of said X-, Y-, and Z-detection signals.

7. An electronic apparatus as set forth in claim 2, wherein said control means control means performs control for moving said head to a retracted position with priority over control of said processing means when detection of a jolt of said housing by said jolt detecting means and detection of dropping of said electronic apparatus by said drop detecting means compete.

8. An electronic apparatus as set forth in claim 1, wherein

said apparatus further comprises a storage medium storing said content data,

said apparatus further has a memory storing skip list data showing identification data of said content data designated to be skipped in the content data stored on said storage medium, and

said control means adds identification data of said content data being played back to said skip list when said jolt detecting means detects a jolt of said housing while said processing means is playing back the content data.

9. An electronic apparatus as set forth in claim 8, wherein said control means makes said processing means perform processing for playback of content data corresponding to identification data other than identification data shown by said skip list stored in said memory in a predetermined operation mode and adds identification data of said content data being played back to said skip list when a jolt of said housing is detected by said jolt detecting means.

10. An electronic apparatus as set forth in claim 1, wherein

said apparatus further has a memory storing favorite list data showing identification data of favorite content data of a user in content data stored in said storage medium, and

said control means add identification data of said content data being played back to said favorite list data when said processing means is playing back said content data and said swing detecting means detects said rocking in a predetermined rocking direction.

11. An electronic apparatus as set forth in claim 10, wherein

said apparatus further has swing detecting means for detecting rocking of said electronic apparatus and a rocking direction, and

said control means makes said processing means perform processing for playback of said content data corresponding to said identification data shown by said favorite list data stored in said memory with priority and adds identification data of said content data being played back to said favorite list data when said swing detecting means detects said rocking in a predetermined rocking direction while said processing means is playing back content data.

12. An electronic apparatus as set forth in claim 1, wherein

said electronic apparatus further comprises a swing detecting means for detecting rocking of said electronic apparatus and a rocking direction, and

said control means performs processing for moving the cursor on said operation screen or switching said operation screen when said swing detecting means detects said rocking in a predetermined rocking direction during display of an operation screen on a display.

13. An electronic apparatus as set forth in claim 1, wherein

said electronic apparatus further comprises

a memory storing first list data showing identification data of said content data having a first attribute and second list data showing identification data of said content data having a second attribute in content data stored in said storage medium and

a swing detecting means for detecting a speed of rocking by said electronic apparatus, and

said control means makes said processing means perform processing for playing back content data of identification data shown by said first list data when said swing detecting means detects rocking of a speed of a predetermined threshold value or more and makes said processing means perform processing for playing back content data of identification data shown by said second list data when said swing detecting means detects rocking of a speed less than a predetermined threshold value.

14. A data processing method run in electronic apparatus playing back content data, comprising

a first step of using acceleration detected by an acceleration sensor housed in a housing of said electronic apparatus to detect if said housing has been jolted and

a second step of performing predetermined processing relating to said content data when detecting that said housing has been jolted at said first step.
