Abstract: An image flow analyzing method with low datum storage and low datum computation is applied to a related camera device and a related camera system. The image flow analyzing method includes defining a monitoring region on a video image, detecting an input timing and an output timing of an object passing through the monitoring region, utilizing the input timing and the output timing to compute a first average staying amount and a first average staying period of the object within the monitoring region via a specific time length, and utilizing the first average staying amount and the first average staying period to compute a second average staying amount and a second average staying period of the object within a statistics range defined by several specific time lengths in accordance with an external command.

Abstract: A queue information analyzing method is applied to an image analyzing apparatus. A monitoring image captured by the image analyzing apparatus has a triggering area. The queue information analyzing method includes identifying a first candidate object stayed within the triggering area, forming a sampling range via the first candidate object, determining whether a second candidate object stayed within the sampling range belongs to a queue of the first candidate object, and acquiring an amount and a accumulated time of candidate objects about the queue.

Abstract: An object counting device includes an image capturer and a processor. The image capturer captures an image sequence related to a gate within a field of view. When an object in the image sequence passes through an entry/exit reference corresponding to the gate, the processor determines a moving direction of the object. When the processor determines that the object moves from a first side of the gate towards a second side of the gate, the processor counts the object into a first accumulated number. When the object exits from the field of view, the processor records an exit position of the object. The processor determines whether to count the object into a second accumulated number according to the exit position.

Abstract: An object recognition system includes an image capturing unit, a motion sensing module, a receiver and a processor. The image capturing unit captures an image sequence. The motion sensing module is disposed on a target object and includes a transmitter and a motion sensor. The motion sensor selectively drives the transmitter to transmit a plurality of wireless signals according to a plurality of motion states of the target object. The receiver receives the wireless signals. The processor analyzes the image sequence to obtain at least one first motion state curve corresponding to at least one object, generates a second motion state curve corresponding to the target object according to the wireless signals, and determines whether to recognize the object corresponding to the first motion state curve as the target object according to a correlation between the first motion state curve and the second motion state curve.
