It is the perspective view which looked down at the digital camera 100 from diagonally forward. 1 is a diagram illustrating an internal structure of a digital camera 100. FIG. It is the perspective view which looked down at the digital camera 100 from diagonally backward.

  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a perspective view of the digital camera 100 as viewed from diagonally forward. The figure shows the state of the digital camera 100 when it is carried as a portable device.

  Note that the front refers to the subject side with respect to the digital camera 100. Further, upper, lower, left, and right described in the following description indicate the positional relationship on the drawing in the state depicted in each drawing. Therefore, the meanings of “up”, “down”, “left”, and “right” are not always in the same direction in other drawings or other forms.

  The digital camera 100 includes a substantially rectangular parallelepiped casing 110 and a cover member including a grip portion 130 and a front cover 140 disposed on the surface of the casing 110. The grip part 130 covers the front surface and the upper surface on the left side of the housing 110 in the drawing. The front cover 140 is disposed on the front surface of the housing 110.

  The grip part 130 has a surface continuous with the housing 110. However, a seam 111 is formed between the housing 110 and the grip part 130. The seam 111 is continuous with the upper surface of the housing 110. Further, the seam 111 makes a round around the digital camera 100 continuously on the back surface and the bottom surface, which is not visible in the drawing. Also, a release button 122 and a push button 124 are disposed on the upper surface of the grip portion 130, and a finger hook portion 132 is disposed on the front surface of the grip portion 130.

  The release button 122 has a two-stage function corresponding to the amount of depression. That is, when the release button 122 is pressed halfway down, the automatic focusing mechanism of the digital camera 100 is activated and the imaging optical system is focused. When the release button 122 is fully pressed down, the digital camera 100 is instructed to start image acquisition.

  As described above, the release button 122 is pressed down by the user when the digital camera 100 is instructed to start focusing and start image acquisition. Therefore, the release button 122 has a size larger than that of the other push buttons 124. Further, the release button 122 is arranged at a position that is easier to press than the other push buttons 124. The push button 124 is assigned, for example, a power switch, switching to a reproduction mode, and the like.

  The finger hook portion 132 protrudes further forward with respect to the front surfaces of the housing 110 and the grip portion 130. The finger hook 132 functions as a finger hook when holding the digital camera 100 to ensure the holding of the housing 110. When the digital camera 100 is gripped using the finger hook 132 as a finger hook, the release button 122 and the push button 124 can be operated with the index finger of the hand holding the digital camera 100.

  It should be noted that activation of the automatic focusing mechanism may be assigned to the half-pressed state of the release button 122 in addition to activation of the automatic focusing mechanism. Further, the user may maintain the half-pressed state for the purpose of maintaining the in-focus state obtained by the automatic focusing mechanism, the exposure conditions obtained by the automatic exposure mechanism, and the like. Further, there may be a function of canceling a part or all of the functions assigned to the half-pressed state of the release button 122.

  In addition, the number of push buttons 124 in the digital camera 100 is not limited, and may be more or less than illustrated. Further, the function of the push button 124 is not limited, and depending on the function of the digital camera 100, start and end of moving image shooting and the like, and on / off of additional functions such as a projector may be assigned.

  FIG. 2 is a perspective view of the digital camera 100 as viewed from diagonally forward. This figure shows the digital camera 100 with the front cover 140 moved to the retracted state and the front lens 152 is not shielded. Elements that are the same as those in FIG. 1 are given the same reference numerals, and redundant descriptions are omitted.

  The front cover 140 is engaged with the front surface of the housing 110 by a pair of guide rails 142 disposed behind the front cover 140. Thereby, the front cover 140 can move up and down in the drawing along the front surface of the housing 110.

  In the state illustrated in FIG. 2, the front cover 140 moves downward along the front surface of the housing 110 as indicated by an arrow A in the drawing. Further, due to the movement of the front cover 140, a front ball 152 and an illumination unit including a flash 162 and an auxiliary light source 164 appear on the upper front surface of the housing 110.

  However, the front cover 140 does not extend out from the front surface of the housing 110 even when the front lens 152, the flash 162, and the auxiliary light source 164 are exposed by sliding. Therefore, the practical dimensions of the housing 110 are not increased by the sliding of the front cover 140.

  The front lens 152 forms a part of the first optical system built in the housing 110. In the illustrated example, the optical system is a bent optical system in which the optical axis is bent downward within the housing 110. In this bending optical system, an image sensor parallel to the bottom surface of the housing 110 is disposed at the end opposite to the front lens 152, and an image corresponding to the subject luminous flux incident from the front lens 152 can be captured.

  When the forced flash mode is set for the digital camera 100 by the user, the flash 162 is set to the timing for starting image acquisition when the automatic flash mode is set for the digital camera 100 and the automatic exposure mechanism instructs the flash. Together, it emits light to illuminate the subject. The auxiliary light source 164 assists the operation of the automatic focusing mechanism by irradiating auxiliary light toward the subject when the amount of light from the subject is insufficient.

  It should be noted that the front ball 152 is arranged close to the right side with respect to the center of the housing 110 including the grip portion 130. Therefore, the user's right hand is attached to the grip part 130 so that the palm faces the side surface of the grip part 130, and at least a part of the middle finger, ring finger, and little finger of the right hand is hung on the finger holding part 132, and the thumb of the right hand is gripped. The digital camera 100 can be securely held by gripping the entire grip part 130 by turning it to the back of the part 130.

  In addition, the finger hook portion 132 and the front ball 152 are arranged at positions separated from each other on the front surface of the housing 110. Therefore, even when the grip portion 130 is gripped by placing a finger on the finger rest portion 132, the front ball 152 does not get a finger.

  Furthermore, the power on of the digital camera 100 may be linked to the movement of the front cover 140 from the state shown in FIG. 1 to the state shown in FIG. That is, when the front lens 152, the flash 162, and the auxiliary light source 164 are covered by the front cover 140, the power of the digital camera 100 is shut off, and the front cover 140 moves to move the front lens 152, the flash 162, and the auxiliary light source 164. If the camera is exposed, the digital camera 100 may be turned on. Thereby, the user's operation procedure for the digital camera 100 can be reduced, and the number of parts assigned to the power switch can be reduced.

  FIG. 3 is a perspective view of the digital camera 100 as viewed from obliquely behind. This figure shows the digital camera 100 in the state shown in FIG. 1 or 2 as viewed from the back side. Elements common to those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

  The seam 111 is continuous from the upper surface to the back surface of the housing 110. On the rear surface of the housing 110, a liquid crystal display unit 170 is disposed on the left side with respect to the joint 111. The liquid crystal display unit 170 is fixed to the back surface of the housing 110 and displays a menu or the like when various settings are made for the operation of the digital camera 100.

  Further, the liquid crystal display unit may overlap a sheet called a “lenticular sheet” on 170, for example. With this sheet, an image displayed on the liquid crystal display unit 170 can be viewed as a right-eye image for the viewer's right eye and as a left-eye image for the left eye. At this time, the image for the left eye and the image for the right eye that are visually recognized by the viewer are images simultaneously (or at a small time interval), and the image for the left eye and the image for the right eye are images having a predetermined parallax. In some cases, the image displayed on the liquid crystal display unit 170 can be viewed stereoscopically by the above-described display. In the present embodiment, the image displayed in this way is referred to as a stereoscopic image.

  It also functions as a viewfinder that displays subject images. Further, the shooting conditions set manually or automatically, the reproduced image of the shot image, the remaining amount of the recording medium, the remaining amount of the battery, and the like are also displayed. Furthermore, a panel (for example, a pressure-sensitive panel) that can be operated in contact with the surface of the liquid crystal display unit 170 may be provided as a part of the operation unit.

  On the back surface of the housing 110, the right side of the joint 111 forms the grip portion 130. A plurality of push buttons 124 and a cross key 126 are further arranged on the rear surface of the grip portion 130. A strap hole 134 is disposed on the side surface of the grip portion 130.

  With such an arrangement, the push button 124 and the cross key 126 on the back surface can be operated with the thumb of the hand holding the digital camera 100 with the finger hook 132 as a finger hook. In addition, the grip portion 130 including the finger rest portion 132 can be held in a state where the wrist is passed through the strap coupled to the strap hole 134.

  Therefore, as shown in FIG. 2, if the front lens 152, the flash 162, and the auxiliary light source 164 are exposed, an image can be taken by operating the release button 122 or the like. Further, as shown in FIG. 1, even when the front lens 152 and the like are covered with the front cover 140, the push button 124 and the cross key 126 and the like can be operated to display an image on the liquid crystal display unit 170.

  In addition to the illustrated one, the digital camera 100 includes other operation members such as a dial and a lever, other display members such as a pilot lamp, a warning buzzer, and a speaker, and other input members such as a microphone. And may be disposed on the surface of the grip portion 130. The digital camera 100 may be provided with a connector such as USB or HDMI, a power supply terminal, or the like. Furthermore, the digital camera 100 may be provided with a socket for inserting / removing a recording medium and a hatch for sealing the socket.

  FIG. 4 is a perspective view of the digital camera 100 as viewed from diagonally forward. This figure shows a state where the grip part 130 is further pulled out to the left side as indicated by an arrow B in the figure from the state shown in FIG. Elements common to FIGS. 1 to 3 are denoted by the same reference numerals, and redundant description is omitted.

  As illustrated, the grip portion 130 can be pulled out to the side with respect to the housing 110. That is, the grip portion 130 is engaged with the front surface of the housing 110 by the guide rail 131 disposed therein. Thereby, the grip part 130 can move with respect to the housing | casing 110 to the one of the width direction of the housing | casing 110 (left side in a figure).

  When the grip portion 130 is pulled out, the grip portion 130 still covers the side end portion of the housing 110 and a part of the front surface, the upper surface, the back surface, and the lower surface. However, the front side hidden surface 113, the upper surface side hidden surface 116, and the like of the housing 110 are exposed as much as the grip portion 130 is pulled out.

  Thereby, another front ball 154 arranged on the front surface of the housing 110 is exposed to the outside. In other words, the front ball 154 is arranged close to the left side in the drawing with respect to the center of the housing 110 and forms a part of the second optical system. As shown in FIGS. 1 to 3, when the grip portion 130 is in the stored state, the front ball 154 is covered by the front surface of the grip portion 130. However, when the grip part 130 is pulled out to the same left side as the left side of the digital camera 100 in which the front ball 154 is arranged, the front ball 154 is exposed to the outside.

  Further, in the pulled out grip part 130, the finger hook part 132 is located further to the left than the front ball 154. Therefore, the digital camera 100 can be held without blocking the front ball 154 by gripping the finger hook portion 132.

  Here, the release button 122 and the push button 124 are disposed on the upper surface of the grip portion 130. Therefore, the release button 122 and the push button 124 move to the left in the drawing with respect to the housing 110 together with the grip portion 130 that has been pulled out and moved. Accordingly, even when the grip portion 130 is pulled out, the relative positions of the release button 122 and the push button 124 and the finger hook portion 132 are not changed.

  As a result, even when the grip part 130 is pulled out and extended, the digital camera 100 is held with the finger hook part 132 as a finger hook and the release finger is used with the index finger of the same hand as when the grip part 130 is housed. The button 122 and the push button 124 can be easily operated. Therefore, the user can instruct the digital camera 100 to start image acquisition at the intended timing by fully pressing the release button 122.

  Further, a notch 136 is partially formed on the front surface of the grip portion 130. Thereby, when the grip part 130 is pulled out to be in the extended state, the front ball 154 appears on the left side in the pulling direction as compared with the part where the notch 136 is not formed.

  In view of the above effects, the position of the grip portion 130 pulled out from the housing 110 is the same as the position of the front ball 154 that appears after the grip portion 130 is pulled out with respect to the center of the housing 110. A direction component is preferably included. However, the movement path until the grip part 130 is completely pulled out may contain any component. That is, as shown in the drawing, the pulled-out grip part 130 may move linearly. Moreover, the movement of the grip part 130 may include components such as rotation and swinging in the process of reaching the extended state.

  Note that a step 115 having a shape complementary to the shape of the notch 136 is disposed on the front surface of the housing 110 in a region where the notch 136 is located when the grip portion 130 is in the retracted state. The region surrounded by the step 115 is raised from the front side hidden surface 113 and forms a surface continuous with the front surface of the housing 110. Thereby, when the grip part 130 will be in the accommodation state, the grip part 130 and the housing | casing 110 will make the surface which continued smoothly.

  Further, the upper surface side hidden surface 116 is provided with a relief 117 spaced from the inner surface of the grip portion 130. The relief 117 extends to the left end of the housing 110 under the grip portion 130. Thereby, the internal structure of the release button 122 and the push button 124 arranged on the upper surface of the grip part 130 can pull out the grip part 130 without interfering with the housing 110 inside the grip part 130.

  Further, even when the grip part 130 is pulled out, the grip part 130 and the housing 110 overlap each other around the entire circumference except the notch 136. Therefore, the length of the coupling part between the grip part 130 and the housing 110 is sufficiently long, and the rigidity of the coupling part can be increased.

  FIG. 5 is a schematic diagram showing the internal structure of the digital camera 100. The figure shows a state in which the state of the members arranged inside the housing 110 is viewed from the front side of the digital camera 100 in the digital camera 100 shown in FIG. Elements common to FIGS. 1 to 4 are given the same reference numerals, and redundant description is omitted.

  A housing 110 of the digital camera 100 includes a battery 112, a main substrate 114, a pair of optical systems 151 and 153, a flash 162, and an auxiliary light source 164. The pair of optical systems 151 and 153 are arranged along both side ends of the housing 110. Accordingly, the front balls 152 and 154 of the optical systems 151 and 153 are arranged symmetrically with respect to the center line C of the housing 110 at the upper right and upper left corners of the housing 110.

  The optical systems 151 and 153 image subject light beams incident from the front balls 152 and 154 on an image sensor (for example, two CMOS sensors), convert the subject image into an electrical signal, and are digitized. Can be recorded above.

  The release button 122 disposed on the upper surface of the grip unit 130 can instruct the timing to start image acquisition via at least one of the pair of optical systems 151 and 153. At this time, a control unit (not shown) records the captured image data after digitization processing corresponding to the electrical signal from at least one image sensor on the recording medium. In addition, the release button 122 can instruct both the pair of optical systems 151 and 153 to start image acquisition at the same timing in a single operation. At this time, a control unit (not shown) records a pair of two photographic image data after digitization processing corresponding to the electric signal from each imaging element in a recording medium in association with each other.

  The pair of image data acquired by the pair of optical systems 151 and 153 by such an operation becomes, for example, a right-eye image and a left-eye image having a predetermined parallax with each other. Therefore, a stereoscopic image can be displayed by combining these pair of images. Specifically, the control unit (not shown) combines the left-eye image and the right-eye image having a predetermined parallax recorded on the recording medium to generate a stereoscopic image, and the combined stereoscopic image is displayed on the liquid crystal. The display unit 170 is controlled to display. Further, a control unit (not shown) may record this stereoscopic image on a recording medium. For example, this stereoscopic image is an image synthesized by a control unit (not shown) so that the column components of the right-eye image and the column components of the left-eye image are alternately arranged.

  Note that when one front lens 154 is covered by the grip portion 130, the subject luminous flux does not enter the front lens 154 of the optical system 153. Therefore, a subject image cannot be captured via the optical system 153. Therefore, when the grip portion 130 is in the retracted state and covers the front ball 154, the reflection of the operation by half-pressing and full-pressing the release button 122 may be invalidated for one optical system 153.

  A flash 162 and an auxiliary light source 164 are disposed between the pair of optical systems 151 and 153. A battery 112 is housed between the optical systems 151 and 153 and below the flash 162 and the auxiliary light source 164. Further, a main substrate 114 is arranged in parallel to the paper surface behind the battery 112, the flash 162, and the auxiliary light source 164. With such a layout, the distance between the front balls 152 and 154 can be increased with respect to the width of the housing 110.

  Here, the flash 162 and the auxiliary light source 164 are arranged at the center of the pair of front balls 152 and 154. In addition, as indicated by a symbol D in the drawing, the pair of optical systems 151 and 153 are arranged symmetrically with respect to the center line C of the housing 110. With such a layout, the flash 162 and the auxiliary light source 164 can cause flash light and auxiliary light to act on both the optical systems 151 and 153 under symmetrical conditions.

The front lens 154 is covered by the grip portion 130 in the accommodated state, as shown by the arrow V ₁ in the drawing is disposed closer to the left side in the drawing with respect to the center line C of the housing 110. Therefore, the position of the optical system 153 which includes a front lens 154, as shown by the arrow V ₂ in the figure, located on the left side in the figure with respect to the center line C. The position of the optical system 153 may be the geometric center of the optical system 153 in the front view, or may be the position of the center of gravity of the optical system 153 in the actual machine.

  The extended position of the extended grip portion 130 with respect to the position of the optical system 153 as described above is also on the left side in the drawing with respect to the retracted position as indicated by an arrow B in the drawing. In this way, by including the component in the direction of the optical system 153 with respect to the center line C of the housing 110 in the direction of the extended state with respect to the retracted state of the grip portion 130, the extended grip portion 130 is made more than the optical system 153. Positioning on the outer edge side makes it easy to grip the finger hook portion 132.

  Note that the positional relationship between the retracted state and the extended state of the grip portion 130 only needs to include the same components as the positional relationship of the optical system 153 with respect to the center line C, and the two are not necessarily the same. That is, when the optical system 153 is located to the left of the center line C, the positional relationship between the retracted state and the extended state further includes a horizontal component to the left, and further to the housing 110. And components that extend downward, upward, forward, or rearward.

  The optical systems 151 and 153 are hidden inside the housing 110 and have shapes different from the front balls 152 and 154 that appear outside. However, since the optical systems 151 and 153 are inseparable from the front balls 152 and 154, the arrangement of the front balls 152 and 154 and the arrangement of the optical systems 151 and 153 have the same tendency. Therefore, by including the components in the arrangement direction of the optical systems 151 and 153 in the moving direction of the finger hanging part 132, the finger hanging part 132 can be easily held without causing the front ball 154 to be caught in the extended state.

  Further, in the above example, the grip portion 130 has moved sideways along the surface of the housing 110. However, the movement of the grip part 130 from the stored state to the extended state and the movement from the extended state to the stored state are not limited to linear translation. That is, the movement path of the grip part 130 may be bent. Moreover, the movement of the grip part 130 may include a rotational motion or the like.

  For example, as an example of the digital camera 100 including the pair of optical systems 151 and 153, there is a stereoscopic imaging device that captures a stereoscopic image. In a stereoscopic imaging device, it is required to provide an interval between a pair of front balls 152 and 154 so that a person can feel parallax. On the other hand, the digital camera 100 as a portable device is required to reduce the size of the housing 110. For this reason, the front balls 152 and 154 are forced to be arranged in the vicinity of the peripheral edge portion of the housing 110.

  As a result, when the front balls 152 and 154 are arranged in the vicinity of the peripheral portion of the housing 110, fingers of a hand gripping the housing 110 from the side are likely to be caught on the front balls 152 and 154. However, in the digital camera 100, the grip portion 130 including the finger hook portion 132 can be pulled out further to the side than the one front ball 154 disposed on the peripheral portion of the housing 110.

  As described above, the digital camera 100 includes the grip portion 130 that extends to the outside of the housing 110 when compared with the housed state. The grip part 130 that extends and is positioned in the extended state includes a finger hook part 132 that can be hooked and gripped without blocking the optical system 153 including the front ball 154. Accordingly, the digital camera 100 can be reliably held without placing a finger on the front ball 154 disposed on the peripheral edge of the housing 110.

  FIG. 6 is a perspective view of the digital camera 100 as viewed from obliquely rearward. This figure shows a state where the digital camera 100 in the state shown in FIG. 4 is looked down from the back side. Elements that are the same as those in the other drawings are given the same reference numerals, and redundant descriptions are omitted.

  In the state shown in the figure, the grip part 130 is pulled out to the right side in the drawing with respect to the housing 110. In addition, operation units such as a release button 122, a push button 124, and a cross key 126 arranged on the surface of the grip unit 130 are also moved to the right together with the grip unit 130.

  Accordingly, the positional relationship between the positions of the release button 122, the push button 124, the cross key 126, and the side end of the digital camera 100 does not change. Therefore, even when the grip 130 is pulled out, the same operability as that of the digital camera 100 in the state shown in FIG. 3 is maintained.

  Further, when the grip portion 130 is pulled out, the back side hidden surface 119 of the housing 110 is exposed even on the back side of the digital camera 100. A plurality of hidden surface buttons 128 are arranged on the back side hidden surface 119.

  The hidden surface button 128 may be assigned a change operation function that is used only when the grip portion 130 is pulled out and the front ball 154 is exposed. That is, for example, correction for adjusting the size of the predetermined parallax described above, correction of the number of columns when the column components of the right-eye image and the column components of the left-eye image are alternately arranged, etc. The hidden surface button 128 may be assigned to change the unique parameter in the stereoscopic image.

  The correction described above is executed by a control unit (not shown) according to the operation of the hidden surface button 128, and the corrected stereoscopic image is displayed on the liquid crystal display unit 170 by the control unit (not shown) or recorded on a recording medium. Let me record. Further, a hidden surface button 128 may be assigned to an operation of changing a parameter when reproducing a stereoscopic image in association with stereoscopic image capturing. Thereby, when one optical system 153 is covered by the grip part 130, it is possible to prevent an operation that acts on the covered optical system 153 from occurring.

  Further, the operation of the hidden surface button 128 is accompanied by an operation of bringing the grip portion 130 into the extended state. Therefore, an operation having a great influence on an erroneous operation such as deletion of a saved file or initialization of a recording medium may be assigned to the hidden surface button 128.

  The digital camera 100 can cover the front balls 152 and 154, the flash 162, and the auxiliary light source 164 by closing the grip 130 and the front cover 140. Therefore, when carrying, dust etc. can be prevented from adhering to the front balls 152, 154, the flash 162, and the auxiliary light source 164.

  In addition, the digital camera 100 includes a pair of optical systems 151 and 153 that can capture a stereoscopic image, but has an outer dimension close to that of a planar image imaging device when the grip unit 130 is in the retracted state. Further, with respect to the center of the housing 110, the front ball 152 is disposed on one side, and the finger hook 132 is disposed on the other side. Therefore, the digital camera 100 can be reliably held and photographed without blocking the subject luminous flux incident on the front lens 152 with a finger or the like.

  Furthermore, in the digital camera 100, when the grip portion 130 is pulled out to be in the extended state, the finger hook portion 132 extends to the outside of the housing 110. Accordingly, the digital camera 100 can be reliably held by gripping the grip portion 130 without blocking the subject luminous flux incident on the front lens 154.

  Furthermore, when the release button 122 and the push button 124 are arranged on the grip part 130, the release button 122 and the push button 124 move with respect to the housing 110 together with the grip part 130. Therefore, regardless of the position of the grip part 130, the release button 122 and the push button 124 can be operated by the index finger of the hand holding the grip part 130.

  In addition, since the grip portion 130 as described above is provided, the pair of optical systems 151 and 153 for taking a stereoscopic image can be arranged so as to be separated to the full width of the housing 110. Therefore, it is possible to capture a stereoscopic image that makes it easy to feel the stereoscopic effect due to parallax.

  Further, by providing a notch 136 on the front surface of the grip part 130, when the grip part 130 is moved to the extended state, the front lens 154 of the optical system 153 disposed on the entire periphery of the housing 110 is exposed. be able to. Even in the extended state, a large amount of overlap between the casing 110 and the grip portion 130 can be left, so that the rigidity of the coupling portion between the casing 110 and the grip portion 130 can be increased.

  Furthermore, when the grip part 130 is in the retracted state, the optical system 153 that cannot be used is assigned to the hidden surface button 128 by assigning an operation that reflects the result to the optical system 153 covered by the grip part 130. The operation of the target hidden surface button 128 can be prohibited. Further, when the grip portion 130 is in the extended state and the optical system 153 can be used, the hidden surface button 128 whose operation result is reflected in the optical system 153 is also operable. As described above, in the digital camera 100, since the member to be operated and the member reflecting the operation result appear or are hidden, an erroneous operation can be prevented in advance.

  In the above example, the notch 136 is provided in the grip part 130 so that the overlap between the grip part 130 and the housing 110 remains wide even when the grip part 130 is in the extended state. However, by devising the structure of the guide rail 131 for engaging the grip part 130 and the housing 110, the notch 136 can be omitted and the shape of the grip part 130 can be simplified.

  In the above example, each of the optical systems 151 and 153 has been described as including an image sensor, but the pair of optical systems 151 and 153 may share a single image sensor. In this case, the subject images formed by the pair of optical systems 151 and 153 are individually converted into electrical signals with a slight time difference and recorded, thereby recording images corresponding to the respective optical systems 151 and 153. it can.

  Furthermore, in the above-described example, it has been described that when using a single optical system, the front cover 140 is opened and the optical system 151 including the front ball 152 is used. However, the grip 130 may be slid sideways with the front cover 140 closed to expose the front ball 154 and record an image using the optical system 153. In this case, since the flash 162 is covered with the front cover 140, when the optical system 153 is used alone, the light emission prohibition mode is automatically set.

  Furthermore, a power switch function may be assigned to the grip part 130 and the front cover 140. That is, when both the grip part 130 and the front cover 140 are closed, a function of cutting off the power supply of the digital camera 100 may be provided. In addition, when either the grip unit 130 or the front cover 140 is opened, a function of turning on the power may be set so that imaging using the opened optical systems 151 and 153 can be performed. Furthermore, when both the grip part 130 and the front cover 140 are opened, a function of switching the operation of the digital camera 100 to the stereoscopic image capturing mode may be provided.

  Furthermore, the specifications of the pair of optical systems 151 and 153 may be different from each other. For example, by making the characteristics of the imaging elements included in the optical systems 151 and 153 different, the optical system to be used may be selected according to the imaging conditions. Further, by making one optical system, which is considered to be often used alone, higher performance and simplifying the other optical system, the overall performance of the digital camera 100 is raised and the product cost is increased. Can be suppressed.

  As described above, the digital camera 100 has been described as an example, but the feature of the portable device is that the input / output unit must be disposed on the peripheral portion of the casing for some reason in the portable device that is required to be downsized. Widely applicable when there is. The present invention can also be applied to composite portable devices such as an imaging device and a projector, a telescope and a distance measuring device.
